That’s what these new age steering wheel holders need to take their road test on! An old Mack or a Brockway with twin clubs ,no air ride seat,and Armstrong steering!,,,, God Bless America!
It would be nice to know how but 18 gears on one stick is the most anyone would reasonably have to deal with. It should be required that they at least know how to drive manual but a lot of companies are caving and buying automatic so a lot of people getting their CDL took notice and made the “problem” worse by ensuring that they aren’t even allowed to drive a 7 speed much less deal with shifting two transmissions at the same time. These twin sticks also have a lot of pointless gear ratios like for 5+4 you shift 1+1, 2+1, 1+2, 1+3, 1+4, 2+2, 2+3, 2+4, 3+2, 3+3, 3+4, 4+2, 4+3, 5+3, 5+4 where the first number is the main box and the second in the auxiliary or “brownie” and in 6+4 it’s 1+1, 1+2, 1+3, 1+4, 2+2, 2+3, 2+4, 3+2, 3+3, 3+4, 4+2, 4+3, 5+3, 6+3, 6+4. You have 20 ratios on 5+4 but you only use 14 of them and 24 on 6+4 but only use 15 of them. Give me an 18 speed any day. More used ratios hauling 155,000 pounds, fewer sticks to deal with, and you don’t have to worry about the auxiliary getting stuck or a double neutral situation. For 5+4 the 14 ratios actually used are 13.8:1, 7.94:1, 6.52:1, 5.45:1, 4.55:1, 3.74:1, 3.13:1, 2.61:1, 2.1:1, 1.76:1, 1.47:1, 1.2:1, 1:1, 0.84:1, 0.7:1. There is a lot of overlap with these. 6+4 in order if you actually shifted all 24 is 11.9:1 in 1+1, 9.29:1 in 1+2, 7.49:1 in 1+3, 6.49:1 in 2+1, 6.07:1 in 1+4, 5.06:1 in 2+2, 4.08:1 in 2+3, 3.56:1 in 3+1, 3.3:1 in 2+4, 2.78:1 in 3+2, 2.24:1 in 3+3, 1.97:1 in 4+1, 1.81 in 3+4, 1.59:1 in 5+1, 1.54:1 in 4+2, 1.34:1 in 6+1, 4+3 and 5+2 are both 1.24:1, 6+2 is 1.04:1, 4+4 is 1.004:1, 5+3 is 1:1, 6+3 is 0.84:1, 5+4 is 0.81:1, and 6+4 is 0.68:1. That’s why you skip auxiliary low everything but 1st gear, overdrive on 4, the auxiliary shifts completely on 5, and once in 6 you only have one faster ratio caused by dropping the auxiliary in 4. 11.9:1, 9.29:1, 7.49:1, 6.07:1, 5.06:1, 4.08:1, 3.3:1, 2.78:1, 2.24:1, 1.81:1, 1.54:1, 1.24:1, 1:1, 0.84:1, 0.68:1. 15 used ratios. Compared to 18 speed. Low Low 14.4:1, Low High 12.29:1, 1 Low 8.56:1, 1 High 7.3:1, 2 Low 6.05:1, 2 High 5.16:1, 3 Low 4.38:1, 3 High 3.74:1, 4 Low 3.2:1, 4 High 2.73:1, (go to high range) 5 Low 2.29:1, 5 High 1.95:1, 6 Low 1.62:1, 6 High 1.38:1, 7 Low 1.17:1, 7 High 1:1, 8 Low 0.86:1, 8 High 0.73:1. Shifting all 18 there is no overlap. You don’t have to split low range unless you’re 120,000+, you don’t have to split any of them if you’re 80,000 or less, you don’t need Low unless you’re heavy, you don’t need 1st unless you are loaded, and you can even skip 2nd and maybe* 3rd if you are bobtail. *If you skip 3rd, the same H pattern position as Low but in high range is the same ratio as 4 in Low range. Only 5 gears used if you do this but be careful because it’ll launch pretty hard and you’d be better off taking off in 3rd and shifting only 6 gears splitter high the whole way.
@@dustinfurness2155 You didn't mention the tri plex, where with it, you have 15 gears, and all are usable. In the days those were popular, they were needed. Low horsepower/Torque ment you needed lots of gears just to get a truck moving. Personally I liked the 5+4 as you said it had a lot of unusable gears. However, with both transmissions in low gear, it was easy to move just about any load. Today, we have big horsepower and Torque so there's no need for those kinds of transmissions. I put a lot of miles on trucks with 2 shifters. Today a 10 speed can do as good a job as most 13, or 18 speeds can. For heavy haul I too would prefer either a 13, or 18. It isn't a big job to make a 13 into an 18 either.
@@bertgrau3934 Yea. There were a couple different triplex transmissions and at least one of them you’d have access to all 15 different gear ratios without doing something stupid like shifting the auxiliary to 2 then back to 1 to shift the main to 2 then after that shift the auxiliary to 2 then the main to 3 and the auxiliary to 1 to return to 1 in the main and 3 in the auxiliary. At least one of the triplex transmissions was as simple as from 1 in the main shift all 3 in the auxiliary then shift to 2 in the main and repeat all 3 in the auxiliary then 3 in the main and all 3 in the auxiliary and so on. The 5+4 “20 speed” was more like a 5+4 “18 speed” but with one set of ratios it was 2, 3, and 4 in the auxiliary (Lo, Direct, OverDrive or something to that effect) where another you’d only shift the 3rd and 4th auxiliary in the “20 speed” where the “18 speed” also consisted of at least 2 combinations but for neither of them would you actually use all 18 gears and in both of them the 2 gear positions the instructions told you not to use were within .01 of what they were in 4th gear but in one faster position in the auxiliary or something with 5 Lo Lo being something like in between 3 Lo and 3 Direct so you wouldn’t use that gear either. It wound up being for the “18 speed” use Lo Lo only in 1st gear (you could also use 2 Lo Lo before 1 Lo but that’s just too much work) and then ignore Lo Lo as you use all 3 of the other auxiliary positions in 2nd, 3rd, and 4th gear and then oops gotta skip 2 of those in 5th because they are actually slower than the gear you are shifting out of so you just leave the auxiliary in overdrive as you shift from 4th to 5th. 4+3+3+3+1 auxiliary positions each gear or the “18 speed” was really like a 14 speed with an optional 15th gear at 2 Lo Lo that was slower than 1 Lo while the 20 speed added either 1 or 2 gears depending on whether you use 5 Lo or not. 15/16 speed “20 speed” transmission. If they were to do something like put a splitter on a modern 10 speed that has 34-35% “jumps” and make that splitter a 17-17.5% reduction or increase (depending on whether they went the RTO18 or RTOO13 route) then you’d have a truly usable 20 speed. Then Spicer came up with something that’s basically a super super 10 speed with 4 splits per gear. For their 14, 16, and 18 this was fine with the 18 skipping 2 of them in 5th, the 16 skipping 2 in 4th and 5th each, and the 14 using only the slowest 2 splits in 1st, 2nd, and 3rd and all 4 in 4th and 5th. Not for the 20 though that could have easily been designed as a 4 way splitter all 5 but instead they went the way of 2 for off road and 2 for on highway for every gear with some serious overlap like 5 low on the off road was in between the highway splits for 4th gear. Obviously you wouldn’t shift that way (3 splits 1st, back to 2nd for lo lo, back to first for high, back to 2nd for the middle splits, to third for the lowest split to 2nd for the highest split back to third for the middle splits, etc) as that would be the same problem we run into trying to shift all 4 on the auxiliary in every single main gear in a 6+4 put in the proper sequence from slowest to fastest or like a modern “15 speed” where 3rd on the deep reduction was faster than 1st gear with deep reduction turned off making a modern “15 speed” a 12 speed the way the spicer “20” was actually a 12 speed and the Mack “20” was really only 16 or 17 used gears or the “24 speed 6+4” also itself could only be 15 gears double overdrive skipping auxiliary shifts from 4th gear to 6th gear before dropping the auxiliary in overdrive too or you could switch out the auxiliary and make it more like a 14 speed single overdrive with the direct drive 6 speed but where you only used two positions in the auxiliary for every single gear except 1st where you could use all 4. I looked into a lot of these gear ratios and shift patterns. Twin sticks could be configured to use all of the gear ratios or to have them overlap and cross at weird places. The spicer 20 with 4 position air splitter wasn’t really a 20 speed in the sense that the spicer 14, 16, and 18 speeds were. Then there’s the ZF transmissions that look like they are trying to copy the Eaton Fuller 18 but they did it weird like the 16 didn’t have Low so it was just 4 low, 4 high, split all 8 for 16. The 12 was the same concept but then it was 3 low and 3 high where you could have a 12+2 which is basically a 14 speed but they give you a 2 speed creeper like in the 18 speed that the 16 speed ZF leaves out. Then there’s that weird 13 speed 3 position splitter Eaton that was like shift 1-2-3 in Low, 1-2-3-4-5 in direct, and 1-2-3-4-5 in high before they switched to a 9 speed (5 low, 4 high) where you could only split the 4 gears in high range and why not split all 9 gears and suddenly 18 speed with a pattern like the ZF 16 in terms of which gears you’ll use 90% of the time plus that really slow gear that winds up being roughly 4 low split if you put the splitter in high and the range selector in high at the same time before putting the shifter stick into the Low hole or where a typical 9 speed has 4th gear in low range and high range low hole as basically the same gear ratio such that you skip one or the other leaving you with 9 instead of 10. Mack tells you to skip the last low range gear and Eaton tells you to skip the first high range gear but it seems like all of the manufacturers went the Eaton pattern when they added 13-18 to their lineups.
@@Retired88M I think the gentleman said somewhere in the video that it was a tri plex. I could be wrong. The thing is even if it is a 5 X 4, you would only need the 15 gears he was using.
I never drove an Emeryville, but I did drive a 1966 GMC Crackerbox, 238 horsepower Detroit 5 speed overdrive with a 2 speed drive axle at 2100 RPM speed was 53 MPH.
B Model is beautiful and the best twin stick shifting I've seen in awhile. Imagine climbing a mountain grade with a full load on that's when the fun really comes. But this man is obviously an exceptional driver.
Exactly! I drove a DM607 SX with a 73000GVW for a while. 180 Thermodyne. First OD to second UD and second OD to third UD were shifts that had to be made. I could cheat the rest.
As a kid in '62-'63, my dad worked for a freight line. He loved driving a B61 with a tranny just like this. He would sometimes use both hands to shift both stix. What a great show! Love u dad!!
Best two stick shifting I have seen on YT so far. When I was a kid, I thought "two sticks, two hands". But I learned from the best driver I ever knew...you only need one hand. Keep it smooth, listen to your rpms and she will shift like butter. Just remember to square off your brownie shifts to avoid getting it in a bind.
For me it was always harder when someone was riding with me, let alone getting it on video. Of course there is a reason Mack came out with the 237 hp Maxidyne in 1966. It had a use able torque range from 1200 to 2100 rpm. Truck engines prior to that had a torque range from around 1700 to 2100. When you have twice the torque (use able power) you need half the number of gears to get down the road. I loved driving the Maxidyne. Having driven B models like this for years or 290 Cummins it just seemed so effortless to drive. This is a very pretty truck that's for sure.
I drove a 73 single axle F model Mack sleeper cab that originally had the 237 Maxidyne with the 5 speed Maxitorque . It was great to drive except when it snowed. You had to drive with a feather foot or else you’d break your traction unless your were grossed out then it would just keep digging and pulling. When the engine blew # 5’s rod out the side of the block it was replaced with an older non turbo 673 Thermodyne that you couldn’t lug down like the 237 so their solution was a Roadranger 910 ten speed to keep the RPM’s up. This was a tired piece of iron that was eventually replaced with another rebuilt 237. Now this was a nice setup. Drive it like a 5 speed getting going then split to the high side and motor down the road
That's true. I used to drive a B-61, with a 5 and a 2. It had a by guess and by golly transmission. " By guess that should be 3rd low, by golly I was right."
I had an old 69 ford. The clip that held,the sick in the top of the trans was broke. So you had to drive around with your hand on the,shifter all day. So i asked my wife to scratch my nose. She said NO. So i handed her the gearshifter. It was hilarious.
@@jerrykinnin7941 Back in the early 70s, I drove a KW cabover with a 2 stick 4 x 4. The auxiliary shift handle doubled as the cab jack handle, and just slipped over a square stub that stuck up out of the shift tower island. One day, I had a new driver with me to kind of show him the ropes. He was mesmerized by the whole 2 stick thing, so as we are wheeling down the road, I pulled the stick off the stub and handed it to him and told him he could practice with it.
😂 The first old truck I was tossed into at age 18 was an old autocar with a quad box in it. There was so much play in the sticks that I had to sit at an angle to be able to catch the far side. 😂
I have driven those Mack double shift 5 & 3 trucks. There's not many around anymore. My last one was 43 years ago. I knew a guy who bent his sticks just right and could shift both at once with his finger tips and no clutch. It is a lost art.
Can anyone write out the shift pattern for me. I Love the way those old two shifter shift. Do you only use clutch to start out. What a great restoration on that MACK. Such a smooth shifter that man is. It's a Dieing art. I did Road farming with a JD farm tractor with a side boom mower( Flay) type. I would only use clutch to start, then the 4 gears in say second range, then use clutch to shift to 3rd, and the 4 speed range button, and so on, till you got to speed. I spent a lot of time on Roads traveling to mow area. You drove the Tractor like a vehicle a lot, so there was shifting Transmission, not like you were in field pulling tiller/ plows, ect, just asking for someone to write down shifting pattern please Very nice video to watch this man drive this old wonderful girl.
Got a job driving a brockway roll off with a 5x4. Was a converted logging truck. Actually very easy truck to shift. Drove by sound of engine and didn't even think where the shift levers were. Drivers make it way more difficult than it really is. If you can't shift it and back it up you shouldn't be driving a truck.
simple to use , easy to understand , tons of gears (without need of 3 sticks) , great reliability and dirty cheap to make/produce compared to modern auto/semi auto/air powered/electicaly powerd etc , with 50+ sensors that practicaly nobody needs . Very good video , perfect gearbox , exellent driver !!!
THANKS for the MEMORY of what it was like in my younger days , driving that old Mac , and reminding me how much I appreciate the Air Ride , Power Assist Steering of today .
I'll take your Cascadia, and then delete the troubles ( if you know what I mean )...... I'm 6'2 and as much as I like classic rigs i couldn't work a B model Mack every day.....too cramped on the inside
It's To Bad They Make Trucks With Cheap Plastic Like The Cheap Cars They Make Today. Cascadia Has Lots Of Room But It Will Never Be A Classic Like That Awesome MACK.
@@hoost3056 Me too but am hammered down to 5-11. And the right foot turned sideways trying to work the fuel on DM's and RD's. Macks weren't bent for big guys. I drove a duplex with a 711 and a quad with a 673. No triplex.Plus everything from a Superliner down till I quit. Mack can still be a 4-letter word.
Absolutely beautiful old Mack! Tri-plex was a good set-up, too - just the right amount of gearing, haven't seen too many single axle cabs like that before.
Skeeter, Back in the 50s and early 60s lots of trucks were single drive axle. In the northeast a few dump trailers had 3 axles. Could max out weight that way. I prefer a twin screw myself. I have driven a truck with a single drive axle and tag axle, really don't like those, easy to get stuck.
Credit to the owner. The wagon looks stunning. I love the colour. As for the gear changing it’s nice to see it been done at lower revs and just rubbing them in. It still amazes me how this gear box ever took off as you wait for the over run to get the gear , then you drop back down anther three. I feel like I am missing a technique to over come this problem.
Now that's one Hell of a gear jammer right there!!!!!! That ole boy could put em all to shame no doubt!!!! You had to be a real man and know what you were doing to drive those old Macks those b-61's were some of the finest pulling tractors ever made!!!
Watched my dad drive them for years on his float. This guy’s pretty good but I haven’t seen him with a load on. lol To me , the Mack B-61 absolutely tops them all! The only one I got to drive professionally (lol, if you could call me that in 87) was a gas job Ford gravel truck with the five and four. My dad had to show me and damn once you got on to it was the coolest thing ever. Great video boys! 👌🏾👍🏽👊🏾
Beautiful truck! I do love the old school dash layout and esp. the switchgear, which is both more attractive and looks more useable that modern plastic 'break me now' switches. Thanks for the post!
Be proud of your Father and Grandpa who manage to shift at this level. As many have told, an art of driving. As a tribute, I practice clutchless shifting on my Accord (in Europe we have many manual transmissions)! :-)
Hello Barnabas. In 1975, I learned to drive truck behind the wheel of a B61 with a duplex. Watching this guy shift that triplex is a pleasure. When I was a trucker, I usually shifted without the clutch (“floated the gears”) and it was great fun. I avoid doing so in my Civic because 1) The gearbox is more delicate and prone to damage if I miss a shift, and 2) It causes extra wear to the synchronizers and shortens the life of the transmission. Happy driving!
@@djgrumpygeezer1194 Hello and thanks for your answer! It's great to exchange views with people who know what they are talking about. So you already drove trucks in 1975 when I was born. It's just amazing to handle a machine at this high level and as I have no truck licence I try to get more sophisticated on motorbikes and cars (like as a substitute). It's quite a useless hobby to practice clutchless shifting and I know that synchros are nor made for it, but I'd like to learn always something more and I do it pretty rarely. I never force it in gear and if it starts grinding I clutch immediately. It's a bit of happiness when I get it :) Double clutching is the other thing I love, especially when the transmission is cold or when driving harder (with heel and tow). Thank you for the advice once again and Happy New Year!
Beautiful truck! I had a Mack duplex but it shifted differently than that, both shifters at the same time. It was a 1974 dump truck 180hp. I became a master with that duplex also
When I was a youngster I was working at a delivery company as a helper in a truck like this. Never did drive it but always admired the driver who could
Man the only young time I got to road one of these Browning SOBs about 40 miles without any experience on even a Roadranger I had to stop and start over four times. The little Macks of that era were beautiful though.
I use to drive a 68 Mack dump truck offset cab. That was a real joy to drive. It had one stick for low & high range, then it had a stick for your highway gears. What a bitch.
Sweet old truck! Nice job feelin' those gears too. I felt safer, driving manual, as I felt we had better control of the rig, especially in winter weather. The sound of that non- castrated diesel is a calming music to my ears!! "Eagle Claw" on the flip.
When pulling a heavy load over the same route everyday learn the gears you can skip. Up and down. The loaded truck wants to keep on rolling and you have to force it to slow down or speed up.
Lots of remarks about the shifting job, but I cannot help but notice that engine. That is one well tuned Bulldog, that engine purrs like a well oiled machine. Sounds great.
I ran a 5 speed dump truck with a 4-splitter behind it years ago(20 spds) & would simply leave the aux. in 3rd & run the 5 & if on highway shift the aux. to 4th loaded or empty but really didn't haul too heavy with it. Worked great and made drinking my coffee that much easier....but not as easy as the automatic "trucks" running around today.
Beautiful absolutely beautiful I had a 1960 b61 with a five and four I had a 1986 with a 5 and 2 still can't shift after all these years I don't know if I can still to stick LOL been driving over 40 years now still love a standard transmission they need to get rid of the automatics maybe then we'd have more truck drivers on the road
This is the proper way to drive a twin stick, none of that both hands off the wheel crap that people think is so cool, this is cool, doing it properly.
what a great old truck i'm old enough to remember when these were new my dad would have loved to have owned one back then he did have a twin sticker in an international AB180 and it was fun watching him changing gears when i was a kid he would stick one hand through the steering wheel on one stick &the other hand on the other stick & change up 18 forward gears &four in reverse & a two speed differential
Started truckin' in the mid-90's with mid-60's 5-speed Macks. Haulin' 40' trailers of produce. No power steering, and that 1st gear was a bitch on a hill. I had to use the trolley brake every time. Not nostalgic for the Bad 'Ol Days - just glad I was man enough to get through it.
That is old school "Road Artistry" at it's BEST....B model Mack, twin-stick, and an ol'time gentleman that had that machine eating outta his hands...simply beautiful, and it's all about the gearing...they got rolling right along without breaking a sweat. Amazing (and comical) contrast when GPS lady says "turn left"....haha
I had the opportunity to drive the B model tandem dumps with 5x3. No air shift; no ac. Just two levers, window cranks, and wing windows. Summer time heat rolls up from the transmission cover & back from the firewall. Don't rush the 'ol girl either. The gears will line up when the rpms are right. Love 'em!
My father used to drive a B model. I went with him on one trip when I was a teenager. He and I unloaded a trailer load of 60 pound bags of potatoes. That will make you sweat.
I wanna see a rookie truck driver or a young truck driver try out an old mack tri plex truck. I know a couple older veteran truckers that use to run old macks and like they said. If you can tackle one of those you can handle any rig. One guy learned truck driving in an old B series mack his grandfather owned, they used to haul logs with . He says this video brings back old memories and he absolutely loves this truck in the video.
I don't miss them. Box seat , Armstrong Steering Wheel , Spring ride . I learned on one. My first trip was across interstate 80 going to JFK airport in beautiful Jamaica NY. 😂
Now there you have proper shifting of a Triplex box. splitting up the gears and boxes. You don't to shift all the way through low mid-range and direct. Just use mid range and direct like this man did. And split up the gears and float em . It's a lost art gear jamming.
I used to drive a 1966 Pete 359, with 5 & 4, over 40 years ago, after watching you, I wounder, how I did that ? 😆😆 GREAT VIDEO, Thanks William Orange county, Ca.
I believe this gentleman has done this a few (hundred thousand?) times. Also, the truck seems to be in amazing mechanical condition. I'm guessing someone's very proud of some transmission work.
@ Vincent Enk, because that was the easiest, and quickest way to shift these Ole Gals. You still had to let the RPM's drop, and let em drop into gear on their own when shifting up through, and then when down shifting, you had to bring the RPM's up to get them to drop into the next gear down. Double Clutching was required until a good driver could master the art of floating gears without using the Clutch at all, and just listen to the Engine RPM's, and let them tell you when to shift.
Lost count how many times I’ve watched. Poetry in motion. I’d pay to go for a ride with this chatterbox! ( kidding!) the shifting and the sound and the beautiful Mack is priceless. Hope he can pass down his art
Got my Class 1 on a 54 red Mack in June of 56 so put a lot of miles in one of those. The R series was introduced just around the time I quit driving steady. They were considered a big advancement at the time.
That’s what these new age steering wheel holders need to take their road test on! An old Mack or a Brockway with twin clubs ,no air ride seat,and Armstrong steering!,,,, God Bless America!
It would be nice to know how but 18 gears on one stick is the most anyone would reasonably have to deal with. It should be required that they at least know how to drive manual but a lot of companies are caving and buying automatic so a lot of people getting their CDL took notice and made the “problem” worse by ensuring that they aren’t even allowed to drive a 7 speed much less deal with shifting two transmissions at the same time. These twin sticks also have a lot of pointless gear ratios like for 5+4 you shift 1+1, 2+1, 1+2, 1+3, 1+4, 2+2, 2+3, 2+4, 3+2, 3+3, 3+4, 4+2, 4+3, 5+3, 5+4 where the first number is the main box and the second in the auxiliary or “brownie” and in 6+4 it’s 1+1, 1+2, 1+3, 1+4, 2+2, 2+3, 2+4, 3+2, 3+3, 3+4, 4+2, 4+3, 5+3, 6+3, 6+4. You have 20 ratios on 5+4 but you only use 14 of them and 24 on 6+4 but only use 15 of them. Give me an 18 speed any day. More used ratios hauling 155,000 pounds, fewer sticks to deal with, and you don’t have to worry about the auxiliary getting stuck or a double neutral situation. For 5+4 the 14 ratios actually used are 13.8:1, 7.94:1, 6.52:1, 5.45:1, 4.55:1, 3.74:1, 3.13:1, 2.61:1, 2.1:1, 1.76:1, 1.47:1, 1.2:1, 1:1, 0.84:1, 0.7:1.
There is a lot of overlap with these. 6+4 in order if you actually shifted all 24 is 11.9:1 in 1+1, 9.29:1 in 1+2, 7.49:1 in 1+3, 6.49:1 in 2+1, 6.07:1 in 1+4, 5.06:1 in 2+2, 4.08:1 in 2+3, 3.56:1 in 3+1, 3.3:1 in 2+4, 2.78:1 in 3+2, 2.24:1 in 3+3, 1.97:1 in 4+1, 1.81 in 3+4, 1.59:1 in 5+1, 1.54:1 in 4+2, 1.34:1 in 6+1, 4+3 and 5+2 are both 1.24:1, 6+2 is 1.04:1, 4+4 is 1.004:1, 5+3 is 1:1, 6+3 is 0.84:1, 5+4 is 0.81:1, and 6+4 is 0.68:1. That’s why you skip auxiliary low everything but 1st gear, overdrive on 4, the auxiliary shifts completely on 5, and once in 6 you only have one faster ratio caused by dropping the auxiliary in 4. 11.9:1, 9.29:1, 7.49:1, 6.07:1, 5.06:1, 4.08:1, 3.3:1, 2.78:1, 2.24:1, 1.81:1, 1.54:1, 1.24:1, 1:1, 0.84:1, 0.68:1. 15 used ratios.
Compared to 18 speed. Low Low 14.4:1, Low High 12.29:1, 1 Low 8.56:1, 1 High 7.3:1, 2 Low 6.05:1, 2 High 5.16:1, 3 Low 4.38:1, 3 High 3.74:1, 4 Low 3.2:1, 4 High 2.73:1, (go to high range) 5 Low 2.29:1, 5 High 1.95:1, 6 Low 1.62:1, 6 High 1.38:1, 7 Low 1.17:1, 7 High 1:1, 8 Low 0.86:1, 8 High 0.73:1. Shifting all 18 there is no overlap. You don’t have to split low range unless you’re 120,000+, you don’t have to split any of them if you’re 80,000 or less, you don’t need Low unless you’re heavy, you don’t need 1st unless you are loaded, and you can even skip 2nd and maybe* 3rd if you are bobtail. *If you skip 3rd, the same H pattern position as Low but in high range is the same ratio as 4 in Low range. Only 5 gears used if you do this but be careful because it’ll launch pretty hard and you’d be better off taking off in 3rd and shifting only 6 gears splitter high the whole way.
@@dustinfurness2155
You didn't mention the tri plex, where with it, you have 15 gears, and all are usable. In the days those were popular, they were needed. Low horsepower/Torque ment you needed lots of gears just to get a truck moving. Personally I liked the 5+4 as you said it had a lot of unusable gears. However, with both transmissions in low gear, it was easy to move just about any load. Today, we have big horsepower and Torque so there's no need for those kinds of transmissions. I put a lot of miles on trucks with 2 shifters. Today a 10 speed can do as good a job as most 13, or 18 speeds can. For heavy haul I too would prefer either a 13, or 18. It isn't a big job to make a 13 into an 18 either.
@@bertgrau3934 Yea. There were a couple different triplex transmissions and at least one of them you’d have access to all 15 different gear ratios without doing something stupid like shifting the auxiliary to 2 then back to 1 to shift the main to 2 then after that shift the auxiliary to 2 then the main to 3 and the auxiliary to 1 to return to 1 in the main and 3 in the auxiliary. At least one of the triplex transmissions was as simple as from 1 in the main shift all 3 in the auxiliary then shift to 2 in the main and repeat all 3 in the auxiliary then 3 in the main and all 3 in the auxiliary and so on. The 5+4 “20 speed” was more like a 5+4 “18 speed” but with one set of ratios it was 2, 3, and 4 in the auxiliary (Lo, Direct, OverDrive or something to that effect) where another you’d only shift the 3rd and 4th auxiliary in the “20 speed” where the “18 speed” also consisted of at least 2 combinations but for neither of them would you actually use all 18 gears and in both of them the 2 gear positions the instructions told you not to use were within .01 of what they were in 4th gear but in one faster position in the auxiliary or something with 5 Lo Lo being something like in between 3 Lo and 3 Direct so you wouldn’t use that gear either. It wound up being for the “18 speed” use Lo Lo only in 1st gear (you could also use 2 Lo Lo before 1 Lo but that’s just too much work) and then ignore Lo Lo as you use all 3 of the other auxiliary positions in 2nd, 3rd, and 4th gear and then oops gotta skip 2 of those in 5th because they are actually slower than the gear you are shifting out of so you just leave the auxiliary in overdrive as you shift from 4th to 5th. 4+3+3+3+1 auxiliary positions each gear or the “18 speed” was really like a 14 speed with an optional 15th gear at 2 Lo Lo that was slower than 1 Lo while the 20 speed added either 1 or 2 gears depending on whether you use 5 Lo or not. 15/16 speed “20 speed” transmission. If they were to do something like put a splitter on a modern 10 speed that has 34-35% “jumps” and make that splitter a 17-17.5% reduction or increase (depending on whether they went the RTO18 or RTOO13 route) then you’d have a truly usable 20 speed. Then Spicer came up with something that’s basically a super super 10 speed with 4 splits per gear. For their 14, 16, and 18 this was fine with the 18 skipping 2 of them in 5th, the 16 skipping 2 in 4th and 5th each, and the 14 using only the slowest 2 splits in 1st, 2nd, and 3rd and all 4 in 4th and 5th. Not for the 20 though that could have easily been designed as a 4 way splitter all 5 but instead they went the way of 2 for off road and 2 for on highway for every gear with some serious overlap like 5 low on the off road was in between the highway splits for 4th gear. Obviously you wouldn’t shift that way (3 splits 1st, back to 2nd for lo lo, back to first for high, back to 2nd for the middle splits, to third for the lowest split to 2nd for the highest split back to third for the middle splits, etc) as that would be the same problem we run into trying to shift all 4 on the auxiliary in every single main gear in a 6+4 put in the proper sequence from slowest to fastest or like a modern “15 speed” where 3rd on the deep reduction was faster than 1st gear with deep reduction turned off making a modern “15 speed” a 12 speed the way the spicer “20” was actually a 12 speed and the Mack “20” was really only 16 or 17 used gears or the “24 speed 6+4” also itself could only be 15 gears double overdrive skipping auxiliary shifts from 4th gear to 6th gear before dropping the auxiliary in overdrive too or you could switch out the auxiliary and make it more like a 14 speed single overdrive with the direct drive 6 speed but where you only used two positions in the auxiliary for every single gear except 1st where you could use all 4.
I looked into a lot of these gear ratios and shift patterns. Twin sticks could be configured to use all of the gear ratios or to have them overlap and cross at weird places. The spicer 20 with 4 position air splitter wasn’t really a 20 speed in the sense that the spicer 14, 16, and 18 speeds were. Then there’s the ZF transmissions that look like they are trying to copy the Eaton Fuller 18 but they did it weird like the 16 didn’t have Low so it was just 4 low, 4 high, split all 8 for 16. The 12 was the same concept but then it was 3 low and 3 high where you could have a 12+2 which is basically a 14 speed but they give you a 2 speed creeper like in the 18 speed that the 16 speed ZF leaves out. Then there’s that weird 13 speed 3 position splitter Eaton that was like shift 1-2-3 in Low, 1-2-3-4-5 in direct, and 1-2-3-4-5 in high before they switched to a 9 speed (5 low, 4 high) where you could only split the 4 gears in high range and why not split all 9 gears and suddenly 18 speed with a pattern like the ZF 16 in terms of which gears you’ll use 90% of the time plus that really slow gear that winds up being roughly 4 low split if you put the splitter in high and the range selector in high at the same time before putting the shifter stick into the Low hole or where a typical 9 speed has 4th gear in low range and high range low hole as basically the same gear ratio such that you skip one or the other leaving you with 9 instead of 10. Mack tells you to skip the last low range gear and Eaton tells you to skip the first high range gear but it seems like all of the manufacturers went the Eaton pattern when they added 13-18 to their lineups.
Looks like this one has the 15 speed tri-plex from the way he was only grabbing 3 gears on the 2nd stick
@@Retired88M
I think the gentleman said somewhere in the video that it was a tri plex. I could be wrong. The thing is even if it is a 5 X 4, you would only need the 15 gears he was using.
The best anti theft system ever. The transmission is basically the security system.
@Empty Head It's actually pretty simple. You get the feeling after some time.
@@randomdude9269 Save for the fact that the kid trying to jack it would most likely never worked a manual, let alone a twinstick.
He’s using the clutch I never did driving one!
Not for someone who grew up in one. 😂
Screw that I drove them would rather have power steering and ac with an 18 speed manual transmission and a 625 hp Cummins engine !
My grandfather tried to teach me on a old 62 Emeryville. Never could get the downshift quite right. Those old guys were the best true truckers
Surprised anyone knew what an Emeryville was. 😂
I never drove an Emeryville, but I did drive a 1966 GMC Crackerbox, 238 horsepower Detroit 5 speed overdrive with a 2 speed drive axle at 2100 RPM speed was 53 MPH.
B Model is beautiful and the best twin stick shifting I've seen in awhile.
Imagine climbing a mountain grade with a full load on that's when the fun really comes.
But this man is obviously an exceptional driver.
Best twin stick shifting I've watched yet. He was smooth even on the downshifts. Like someone said earlier....a lost art
you should check out the "Twin Stick Pappy" video some time.
Lazy, one stick at a time. Ride with a guy that makes a compound shift with both hands at once sometime.
@@FerrickOxhide no need for the 2 hand speed bobtailing,,,,,,,. loaded is a different story all together!! 2 hands are a MUST!!
Exactly! I drove a DM607 SX with a 73000GVW for a while. 180 Thermodyne. First OD to second UD and second OD to third UD were shifts that had to be made. I could cheat the rest.
Most kids don't even know what a manual transmission is let alone how to drive one
I've drove a few and this man makes it look simple, Sir your a credit to all truckers!
It's not bad once you get to kno0w what you're doing.
Love that sound and those older Mack's are beautiful trucks.
I was waiting for the exhaust brake noise but it never happened!
Best shifting video I've seen. Totally relaxed, the others rush it trying to show off or something
As a kid in '62-'63, my dad worked for a freight line. He loved driving a B61 with a tranny just like this. He would sometimes use both hands to shift both stix. What a great show! Love u dad!!
Best two stick shifting I have seen on YT so far. When I was a kid, I thought "two sticks, two hands". But I learned from the best driver I ever knew...you only need one hand. Keep it smooth, listen to your rpms and she will shift like butter. Just remember to square off your brownie shifts to avoid getting it in a bind.
Very beautiful truck,hello from Russia
Its a pleasure to watch this....I used to watch my Dad shifting, no grinding. Just like this man, smooth as silk
Beautiful truck and most shifts without using the clutch. There's a man who knows how to drive old trucks. I rode in those as a kid--thanks.
For me it was always harder when someone was riding with me, let alone getting it on video.
Of course there is a reason Mack came out with the 237 hp Maxidyne in 1966. It had a use able torque range from 1200 to 2100 rpm. Truck engines prior to that had a torque range from around 1700 to 2100. When you have twice the torque (use able power) you need half the number of gears to get down the road. I loved driving the Maxidyne. Having driven B models like this for years or 290 Cummins it just seemed so effortless to drive.
This is a very pretty truck that's for sure.
I drove a 73 single axle F model Mack sleeper cab that originally had the 237 Maxidyne with the 5 speed Maxitorque . It was great to drive except when it snowed. You had to drive with a feather foot or else you’d break your traction unless your were grossed out then it would just keep digging and pulling. When the engine blew # 5’s rod out the side of the block it was replaced with an older non turbo 673 Thermodyne that you couldn’t lug down like the 237 so their solution was a Roadranger 910 ten speed to keep the RPM’s up. This was a tired piece of iron that was eventually replaced with another rebuilt 237. Now this was a nice setup. Drive it like a 5 speed getting going then split to the high side and motor down the road
U
Both shift towers are nice and tight. Most of the two stickers I drove back in the day were so worn, you had to chase the sticks all over the cab.
That's true. I used to drive a B-61, with a 5 and a 2. It had a by guess and by golly transmission. " By guess that should be 3rd low, by golly I was right."
I had an old 69 ford. The clip that held,the sick in the top of the trans was broke. So you had to drive around with your hand on the,shifter all day. So i asked my wife to scratch my nose. She said NO. So i handed her the gearshifter. It was hilarious.
@@jerrykinnin7941 Back in the early 70s, I drove a KW cabover with a 2 stick 4 x 4. The auxiliary shift handle doubled as the cab jack handle, and just slipped over a square stub that stuck up out of the shift tower island.
One day, I had a new driver with me to kind of show him the ropes. He was mesmerized by the whole 2 stick thing, so as we are wheeling down the road, I pulled the stick off the stub and handed it to him and told him he could practice with it.
😂 The first old truck I was tossed into at age 18 was an old autocar with a quad box in it. There was so much play in the sticks that I had to sit at an angle to be able to catch the far side. 😂
That's because it's a Mac Triplex marriage transmission
That's no truck..it's a work of art!!!
I have driven those Mack double shift 5 & 3 trucks. There's not many around anymore. My last one was 43 years ago. I knew a guy who bent his sticks just right and could shift both at once with his finger tips and no clutch. It is a lost art.
right on. bend the shafts just right and one hand will do it
My Dad did several million miles on b61s
Always talked about bending the sticks to just the right spot.
Can anyone write out the shift pattern for me. I Love the way those old two shifter shift. Do you only use clutch to start out. What a great restoration on that MACK. Such a smooth shifter that man is. It's a Dieing art. I did Road farming with a JD farm tractor with a side boom mower( Flay) type. I would only use clutch to start, then the 4 gears in say second range, then use clutch to shift to 3rd, and the 4 speed range button, and so on, till you got to speed. I spent a lot of time on Roads traveling to mow area. You drove the Tractor like a vehicle a lot, so there was shifting Transmission, not like you were in field pulling tiller/ plows, ect, just asking for someone to write down shifting pattern please
Very nice video to watch this man drive this old wonderful girl.
Great job shifting. What a beautiful rig. My buddy drove one of those back in the early 70s hauling eggs.
Got a job driving a brockway roll off with a 5x4. Was a converted logging truck. Actually very easy truck to shift. Drove by sound of engine and didn't even think where the shift levers were. Drivers make it way more difficult than it really is. If you can't shift it and back it up you shouldn't be driving a truck.
simple to use , easy to understand , tons of gears (without need of 3 sticks) , great reliability and dirty cheap to make/produce compared to modern auto/semi auto/air powered/electicaly powerd etc , with 50+ sensors that practicaly nobody needs . Very good video , perfect gearbox , exellent driver !!!
that is a sharp Mack and the shifting is top notch!
More amazing than any new truck on the road . A real Jewel .
THANKS for the MEMORY of what it was like in my younger days , driving that old Mac , and reminding me how much I appreciate the Air Ride , Power Assist Steering of today .
I'd give up my 2015 Freightliner Cascadia for that truck in a heartbeat... I miss those ol' trucks...
I don't have one to give up just what I see on youtube but I started to like the older ones but I want an actual working truck
Shouldnt have gotten one in the first place 😅 I am just toying with you
I'll take your Cascadia, and then delete the troubles ( if you know what I mean )...... I'm 6'2 and as much as I like classic rigs i couldn't work a B model Mack every day.....too cramped on the inside
It's To Bad They Make Trucks With Cheap Plastic Like The Cheap Cars They Make Today. Cascadia Has Lots Of Room But It Will Never Be A Classic Like That Awesome MACK.
@@hoost3056 Me too but am hammered down to 5-11. And the right foot turned sideways trying to work the fuel on DM's and RD's. Macks weren't bent for big guys. I drove a duplex with a 711 and a quad with a 673. No triplex.Plus everything from a Superliner down till I quit. Mack can still be a 4-letter word.
Absolutely beautiful old Mack! Tri-plex was a good set-up, too - just the right amount of gearing, haven't seen too many single axle cabs like that before.
almost all tractors over here in DE are 2x4
Skeeter,
Back in the 50s and early 60s lots of trucks were single drive axle. In the northeast a few dump trailers had 3 axles. Could max out weight that way. I prefer a twin screw myself. I have driven a truck with a single drive axle and tag axle, really don't like those, easy to get stuck.
Credit to the owner. The wagon looks stunning. I love the colour. As for the gear changing it’s nice to see it been done at lower revs and just rubbing them in. It still amazes me how this gear box ever took off as you wait for the over run to get the gear , then you drop back down anther three. I feel like I am missing a technique to over come this problem.
Some drivers would shift both sticks at the same time. It would speed things up. It also made missing a gear easier as well.
Now that's one Hell of a gear jammer right there!!!!!! That ole boy could put em all to shame no doubt!!!! You had to be a real man and know what you were doing to drive those old Macks those b-61's were some of the finest pulling tractors ever made!!!
Watched my dad drive them for years on his float. This guy’s pretty good but I haven’t seen him with a load on. lol
To me , the Mack B-61 absolutely tops them all!
The only one I got to drive professionally (lol, if you could call me that in 87) was a gas job Ford gravel truck with the five and four. My dad had to show me and damn once you got on to it was the coolest thing ever.
Great video boys! 👌🏾👍🏽👊🏾
Those shifters are tighter than a bolt action rifle i love it
They must have gone through those boxes to shift that nice, not to mention his talent. That truck is a beauty.
Nice to watch someone who knows what to do and how to do it. First Mack I ever drove was a B- 81 qaud box
The guys that drove these old trucks cross country were tough as nails!!!!!!
Oh how I miss those days of running a B61 back in 1972, a one stack Mack with a window in the back, Jack.
Beautiful truck! I do love the old school dash layout and esp. the switchgear, which is both more attractive and looks more useable that modern plastic 'break me now' switches. Thanks for the post!
I drove a triplex as a sleeper team many years ago. Smoothest shifting I ever experienced.
Be proud of your Father and Grandpa who manage to shift at this level. As many have told, an art of driving. As a tribute, I practice clutchless shifting on my Accord (in Europe we have many manual transmissions)! :-)
Hello Barnabas. In 1975, I learned to drive truck behind the wheel of a B61 with a duplex. Watching this guy shift that triplex is a pleasure. When I was a trucker, I usually shifted without the clutch (“floated the gears”) and it was great fun. I avoid doing so in my Civic because 1) The gearbox is more delicate and prone to damage if I miss a shift, and 2) It causes extra wear to the synchronizers and shortens the life of the transmission.
Happy driving!
@@djgrumpygeezer1194 Hello and thanks for your answer! It's great to exchange views with people who know what they are talking about. So you already drove trucks in 1975 when I was born. It's just amazing to handle a machine at this high level and as I have no truck licence I try to get more sophisticated on motorbikes and cars (like as a substitute). It's quite a useless hobby to practice clutchless shifting and I know that synchros are nor made for it, but I'd like to learn always something more and I do it pretty rarely. I never force it in gear and if it starts grinding I clutch immediately. It's a bit of happiness when I get it :) Double clutching is the other thing I love, especially when the transmission is cold or when driving harder (with heel and tow). Thank you for the advice once again and Happy New Year!
Beautiful truck! I had a Mack duplex but it shifted differently than that, both shifters at the same time. It was a 1974 dump truck 180hp. I became a master with that duplex also
You lucky duck! She sure is a beauty. I've recently seen an old red and black B model with twins running around here still hauling coal buckets in PA.
When I was a youngster I was working at a delivery company as a helper in a truck like this. Never did drive it but always admired the driver who could
Mack's had some of the coolest names for running gear. Thermodyne, triplex, camel back ect.
*Etcetera* *:)* Not ectera x'D
Now that is a unique way to shift. I've never seen that before. He did a heck of a job.
Man the only young time I got to road one of these Browning SOBs about 40 miles without any experience on even a Roadranger I had to stop and start over four times. The little Macks of that era were beautiful though.
I use to drive a 68 Mack dump truck offset cab. That was a real joy to drive. It had one stick for low & high range, then it had a stick for your highway gears. What a bitch.
Love the truck. Another lost art, map reading!!
Sweet old truck! Nice job feelin' those gears too. I felt safer, driving manual, as I felt we had better control of the rig, especially in winter weather. The sound of that non- castrated diesel is a calming music to my ears!! "Eagle Claw" on the flip.
Takes me back to 1967 Winter Haven Florida pulling a load of grapefruit back to the cannery in Eloise in old B-61.
Nothing sounds like a Mack. What a beautiful truck.
Great looking Mack B model. Nice shifting.
Ha Natural reaction at 3:23 with crossing car....I could hear the driver back out of the fuel for just a couple seconds...That thing sounds great!
If I'm not mistaken, I saw it at the truck show in Clifford Ontario a couple of years ago. Beautiful bulldog!
Buy that man a beer
So cool.
This was built back when men were men and only the weak would cry.
When pulling a heavy load over the same route everyday learn the gears you can skip. Up and down. The loaded truck wants to keep on rolling and you have to force it to slow down or speed up.
Lots of remarks about the shifting job, but I cannot help but notice that engine. That is one well tuned Bulldog, that engine purrs like a well oiled machine. Sounds great.
Good call! She started-up pronto and purred the whole time like a top notch machine!
Well that certainly brings back memories of my time in the 60's .
I ran a 5 speed dump truck with a 4-splitter behind it years ago(20 spds) & would simply leave the aux. in 3rd & run the 5 & if on highway shift the aux. to 4th loaded or empty but really didn't haul too heavy with it. Worked great and made drinking my coffee that much easier....but not as easy as the automatic "trucks" running around today.
Beautiful absolutely beautiful I had a 1960 b61 with a five and four I had a 1986 with a 5 and 2 still can't shift after all these years I don't know if I can still to stick LOL been driving over 40 years now still love a standard transmission they need to get rid of the automatics maybe then we'd have more truck drivers on the road
Wish I had an old mack. Best truck ever made
This is the proper way to drive a twin stick, none of that both hands off the wheel crap that people think is so cool, this is cool, doing it properly.
I started in a quad Flintstone, that tri shift was as smooth as I’ve ever seen.
Love the sound of that motor...nice truck!!! Can remember when Maislin Bros. used them.
Love to see gramps and that old truck. I wish i could drive it too
what a great old truck i'm old enough to remember when these were new my dad would have loved to have owned one back then he did have a twin sticker in an international AB180 and it was fun watching him changing gears when i was a kid he would stick one hand through the steering wheel on one stick &the other hand on the other stick & change up 18 forward gears &four in reverse & a two speed differential
i first learned to drive a truck in 1962 on B-61 with Tri-plex. Bringing back memories! Thanks for keeping this old gal on the road.
I think he has done that before ! I can’t imagine driving a rig through the cities and cross country before the freeways were pushed through
i think that’s as cool as it comes for alot of us that do this for a living.
makes me miss driving a manual trans truck even more
I always called that last gear "Gettin Home to Mama".
That ol boy was as smooth as glass wit them sticks
Started truckin' in the mid-90's with mid-60's 5-speed Macks. Haulin' 40' trailers of produce. No power steering, and that 1st gear was a bitch on a hill. I had to use the trolley brake every time. Not nostalgic for the Bad 'Ol Days - just glad I was man enough to get through it.
ahh the ole "lazy shift technique" i miss those days i loved shifting these it was fun and a skillful exp for me
That is old school "Road Artistry" at it's BEST....B model Mack, twin-stick, and an ol'time gentleman that had that machine eating outta his hands...simply beautiful, and it's all about the gearing...they got rolling right along without breaking a sweat. Amazing (and comical) contrast when GPS lady says "turn left"....haha
That is a beautiful rig..and a master at the wheel!
I double agree with every thing Vince B said. He is so right.
I had the opportunity to drive the B model tandem dumps with 5x3. No air shift; no ac. Just two levers, window cranks, and wing windows. Summer time heat rolls up from the transmission cover & back from the firewall.
Don't rush the 'ol girl either. The gears will line up when the rpms are right.
Love 'em!
My father used to drive a B model. I went with him on one trip when I was a teenager. He and I unloaded a trailer load of 60 pound bags of potatoes. That will make you sweat.
That is one beautiful truck, very expertly driven.
I wanna see a rookie truck driver or a young truck driver try out an old mack tri plex truck. I know a couple older veteran truckers that use to run old macks and like they said. If you can tackle one of those you can handle any rig. One guy learned truck driving in an old B series mack his grandfather owned, they used to haul logs with . He says this video brings back old memories and he absolutely loves this truck in the video.
I don't miss them. Box seat , Armstrong Steering Wheel , Spring ride . I learned on one. My first trip was across interstate 80 going to JFK airport in beautiful Jamaica NY. 😂
Now there you have proper shifting of a Triplex box. splitting up the gears and boxes. You don't to shift all the way through low mid-range and direct. Just use mid range and direct like this man did. And split up the gears and float em . It's a lost art gear jamming.
Dear lord that is beautiful...
Some People struggle with one stick shift how about two lol... You Sir did a great job haven't seen something like that.
I used to drive a 1966 Pete 359, with 5 & 4, over 40 years ago, after watching you, I wounder, how I did that ? 😆😆 GREAT VIDEO,
Thanks William Orange county, Ca.
I believe this gentleman has done this a few (hundred thousand?) times.
Also, the truck seems to be in amazing mechanical condition. I'm guessing someone's very proud of some transmission work.

Sweet Shifting!
I always used the two hand approach. One arm through the wheel and shifted both sticks simultaneously.
Why? Not being a smart aleck, would like to know.
@ Vincent Enk, because that was the easiest, and quickest way to shift these Ole Gals. You still had to let the RPM's drop, and let em drop into gear on their own when shifting up through, and then when down shifting, you had to bring the RPM's up to get them to drop into the next gear down. Double Clutching was required until a good driver could master the art of floating gears without using the Clutch at all, and just listen to the Engine RPM's, and let them tell you when to shift.
I learned the same way... left arm through the wheel. But mine was just a duplex... I miss shifting, but I don’t miss that old backbreaker...
Lost count how many times I’ve watched. Poetry in motion. I’d pay to go for a ride with this chatterbox! ( kidding!) the shifting and the sound and the beautiful Mack is priceless. Hope he can pass down his art
Very nice truck. I’ve always like the B series. Perfect shifting I didn’t hear any grinding!!
Well, he grinded a little a few times, but still is very talented!!
That cab interior looks just like it came off the showroom floor.
He's barely using that clutch. Perfectly adjusted shifters. Gorgeous Truck.
Good job with the triplex Lloyd I drove a Rmodle with a triplex learned real quick to not miss a gear or start all over good video
Haha! Same here, I think I was spoiled learning on a new 13 speed. I’m only 20 but I’m restoring our old b model with a 5&3 and I’m just excited.
The guy’s a pro. Pleasure to watch.
That’s what I learned on. Great tractors. Couldn’t kill em.
great video! I love these ol Mack's!! spotless shifting
YOU DON'T HAVE TO DO ANY SPLIT SHIFTING WHEN YOU DON'T HAVE A LOAD ON BUT STILL NICE TO SEE THE OLD BOY STILL HAS HIS SHIT TOGETHER
My dad owned 2 of these .i also drive truck but these ones today are like driving a automatic pick up truck
Got my Class 1 on a 54 red Mack in June of 56 so put a lot of miles in one of those. The R series was introduced just around the time I quit driving steady. They were considered a big advancement at the time.
Wow 😯 nice shifting just like a professional 🤗🤗🤗🙏🙏🙏🙏🙏🌠🌠🌠🌠🌠🌠
