Still nothing like an old "R" model...they definitely didn't ride as well as the newer models today, but they got the job done. BTW, whoever is driving, good job banging gears. Have a blessed week, Jeff
i remember dad tellin me about those. What he taught me to do with those old wagons, was to back under, but not hit the pin hook up your air lines, and hold the trailer brake till you hit the pin.
@dustypete38 the old 12 speeds were awesome, 5 lever shifts and a selector that had low, direct, neutral and reverse. Some had an extra stick for low,low and some had a lever on the dash for it. We used them to pump of tankers, like you said put the selector in neutral and the lever in 4th and throw in the pto....tank trailer empty in no time. I used to love shifting backwards when parking at the truckstop...always got people looking.
the blue button is actually the emergency spring brake release valve. back in the day when only trucks had spring brakes there was a seperate tank on the truck solely for the purpose that, if the driver ran out of air he could temporarily release them to get off the road and move to a safer location.
@mightyjoe2999 its the tractor park button, can only be used when the parking and the trailer supple buttons are in otherwise it doenst do anything. I drive a '96 CL 700 tri axle lowboy tractor for work with a E7 and it has a tractor park button still, some older macks where goofy and had that button so you could keep the rest of the air going in order to run PTOs and other accessories.
I remember pulling a tanker from 73 and that's how I hooked up to it. Those old trailers are hell. Local rock company still has pups that don't have spring brakes and they're pain but there's no sense getting rid of them if they still serve their purpose. Its like the old truck in this video. It still has its purpose no sense in getting rid of it if it still gets the job done.
Macks are terrific and dependable tractors. The only thing I never liked about them is their steering radius. Any Freightliner, Volvo, KW, etc. can steer rings around them.
ken hatfield Mack still makes their own manuals, the Maxitorque, but only in 9,10,13&18 now. They also offer Eaton Fuller's; as well as the M-DRIVE auto
@ledfoot73 haha hell yea man, we still have an 86 RD that is set up that way, its a good transmission once you get used to it. Also we had a lot of older DM with the 2 stick 7 speeds that were also good for 5 speeds in reverse, always a nice feature in a dump or water truck. It really does get people looking when you're grabbing gears in reverse!
Should also note that truck is about as weird as can be, it must have the neutral override switch engaged, shift lever in 4th, PTO engaged and hoist control set to lift in order to run the wet kit for the Trail Eze lowboy trailer! Tough trucks and they last forever but haggard
macks had an air switch that was usually up on top of the dash (in earlier models) until it was relocated onto the front of the dash to control the interaxle lock
ya mean hydraulic brakes, like in a car? yeah, air brake systems are quite a bit different. and you're right, these 12-speeds aren't the most common transmission on the road, even in Mack's, which is the manufacturer they were built by.
I meant locks the brakes. I have driven 2 trucks with the 3 button set up and the blue button on both would just set the brakes on one rear axle while the red did both. I have no idea why though?
You've got to be kidding me? It's the bat signal. haha. Actually they took it out of most trucks after about 1977 or 1978. The old trailers didn't have spring brakes for parking. That blue valve charged the trailer air to set the trailer brakes when you parked it. Still needed a chock block as the air leaked away over time but that's what the blue valve was used for back in the day.
Where I live in Puerto Rico mack trucks old R models are just too common and every single cement company in Puerto Rico have mack R model mixers runing every day
it's the spring brake. the parking brakes, in case all the air in the system drains or leaks out. look up how air brakes in these trucks work, it may help ya better understand it.
Yea that's what that blue valve is for. I wouldn't know it but my dad's been driving since the 70s, and before that his step dad drove that's where he learned it. This question doesn't get asked much anymore as most drivers have never seen a truck with a blue valve. Mack put them in up until the late 80's I believe. Pete and KW got rid of them by 82. I still would like to find a 70s pete with the blue valve to put new drivers in just so they could ask and give a history lesson. Take care
Never dealt with that. Although it does sound stupid. I have an air leak so my trailer is always popped in the morning not matter what. But that is stupid I've always charged the trailer before releasing the tractor. I ain't got time to push in the tractor then the trailer and sit there and wait for bags to air up. Then again my trailer doesn't have an auto dump so it wouldn't make much difference.
To me, nothing better than the sound of classic trucks still working!
First truck I ever drove was a 12 speed Mack. 15 years old driving it around the farm. Best memories ever.
nothing like 5 reverse gears! i love the old 12 spd macks w/ 2spd rears, they can climb trees
Great sounding truck. Nice to see an old classic still at work.
Still nothing like an old "R" model...they definitely didn't ride as well as the newer models today, but they got the job done. BTW, whoever is driving, good job banging gears.
Have a blessed week,
Jeff
Great to see an old mack still workin'
Jen
@snowmanrt440
I'm a fan of the classic Mack engines! I just love that classic Mack growl!
Me too
I think they shift like a super 10. You split every gear.
Yeah
That's correct!
i remember dad tellin me about those. What he taught me to do with those old wagons, was to back under, but not hit the pin hook up your air lines, and hold the trailer brake till you hit the pin.
thats a real work truck. If you can spend 10 hrs. a day driving an old R model mack thats when you know you can drive.
@dustypete38 the old 12 speeds were awesome, 5 lever shifts and a selector that had low, direct, neutral and reverse. Some had an extra stick for low,low and some had a lever on the dash for it.

I love MACK truck's i grew up in a 1968 RL700L logging truck in central cali.
LMFAO is that the hi side of the gearbox whining? great old truck sounds like a many i used to run up in CA. Turbo hiss sounds righteous as well

Good ol' 12 speed my favorite!
nothing like a good old mack
@overtime2005 nah matee the macks had a 12 speed lest you forget that mack makes their own transmissions
ken hatfield Mack still makes their own manuals, the Maxitorque, but only in 9,10,13&18 now. They also offer Eaton Fuller's; as well as the M-DRIVE auto

love these old macks ! i got a few videos up on my channel of mine
Should also note that truck is about as weird as can be, it must have the neutral override switch engaged, shift lever in 4th, PTO engaged and hoist control set to lift in order to run the wet kit for the Trail Eze lowboy trailer! Tough trucks and they last forever but haggard
"Where we goin daddy?" "Just followin' the Bulldog"
thats a cool truck
@hammyman2014 blue button is tractor only parking brakes, yellow is tractor and trailer and red is trailer. Older trucks had this setup.
All a 12 speed is a 6 speed only split between the gears!! You still get the 5 reverse gears with a high/low for forward gears!!!
The sound of the engine
macks had an air switch that was usually up on top of the dash (in earlier models) until it was relocated onto the front of the dash to control the interaxle lock
nice job!
My first truck was a 95 rd688s it had the 10 speed no dynatard brake was the best and worst transmission I ever drove
I apologize for complaining but if that dash fan wasn't running it would have sounded even better.
ya mean hydraulic brakes, like in a car? yeah, air brake systems are quite a bit different. and you're right, these 12-speeds aren't the most common transmission on the road, even in Mack's, which is the manufacturer they were built by.
oh, ya means modern systems. yeah, that blue knob is integrated into the yellow, basically. eliminates the need for that extra knob.
Классное видео! Спасибо!
Bin Ich froh das es hier den Actros, TGX oder Daf gibt...
0.46 just jam it into first gear lol. all you have to do is feather it in and out of gear. no jerking the shifter.
@kurtdog119 Look at the hood. It is not a Superliner it is an R model
esse caminhoneiro tem o dom

pete379exhd2010 Mack still used them in the 90s. Had a 94 Mack with a blue button
whats the blue button for is that a 2nd emergency brake ?
Where I live in Puerto Rico mack trucks old R models are just too common and every single cement company in Puerto Rico have mack R model mixers runing every day
I like everything about Mack but their transmissions
What year is ur Mack?
it's the spring brake. the parking brakes, in case all the air in the system drains or leaks out. look up how air brakes in these trucks work, it may help ya better understand it.
@overtime2005 its definitely a 12 speed mack, drove one myself.
where was this vid taken?
Is that a 350 maxidyne?
Yea that's what that blue valve is for. I wouldn't know it but my dad's been driving since the 70s, and before that his step dad drove that's where he learned it.

pete379exhd2010 I owned a 94 CH613 with a blue valve.
learnt to drive Stick Shift in one of these
BULL DOGG MACK!!!
La mejor caja de transmisión 2080 mack fuerza desplace velocidad y mucha ventaja en reversa
Shamary Taylor Hansell tienes razon y la MACK T-318 LR de 18 velocidades. con una relacion de 28 a 1 en reversa es muy comoda
@snowmanrt440
Mack Super Liner, right?
this is R600?
Never dealt with that. Although it does sound stupid. I have an air leak so my trailer is always popped in the morning not matter what. But that is stupid I've always charged the trailer before releasing the tractor. I ain't got time to push in the tractor then the trailer and sit there and wait for bags to air up. Then again my trailer doesn't have an auto dump so it wouldn't make much difference.
the gear knob needs to be turned 90° to the right, I was wondering why you where holding the shifter that way...
It locks just one of the rears instead of both
ok got ya see i knew around 77 they came out with spring break/parking chambers but i have never seen a valve with blue nob always red and yellow
Blue is tractor parking brakes only.
@hammyman2014 lowers the deck for unloading
what is the blue valve for?
Tractor brakes.
i was drive with daf and in this daf have 16 gears, This is , 8 , but gears can split , multiply 2 , is 16 :P
I drove them and they were 10 spds
better quit grinding them puppys
no i mean plain old airbrakes
well im used to normal trucks not these kinds and not many people use 12 speeds
it's an r-model
i think he have only 6 gears, one gear is splitting , like, 1,1.5, 2,2.5, 3 .....
Esa es una 1070 en ese Mack r 600
No clutch?? How??
san parae time the gears, you need no clutch. It's very common.
You can try it on a car with manual box and synchromesh. It is easy to get it working.
not if your float shifting
You're not going to get all your gears super clean any honest trucker will tell you that. At the very least an old bulldog like that.

No bueno
:)
shifting a truck with the range selector and no clutch is an excellent way to blow out the ring gear.
Yeshua Akbar Bullshit. That's the way it's always been done.
STFU idiot
shut up
13 speed not 12 sir. ;D
Noup is a 12 speed
wrong
