I was a truck driver in the mid 80's & early 90's. Many of the old junk yard tractors had that same low air buzzer. They are mechanical generic devices, from the 60's & early 70's.
Totally. That’s the first thing I thought of was air pressure, based on experience with M35 and other military trucks.
I've first seen adventures made from scratch,Mr good pliers, and diesel creek videos and then scrappy industries.
I'm Number 44
Looooooove Macks!
The Bulldog says it all....
Brilliant channel great work collecting the old mack and getting it started
I’m glad Matt at Diesel Creek recommended you. Great channel!
Way to go Sam! I was so happy when you got that Cummings to lite up😁
Great job getting the engine running. Cant wait to see the truck moving again. Love your videos man.
Can’t wait for the next installment!! Great Job Sam!!
Thank you! Will keep you posted!
Well done bro, were all coming from Matts channel over to yours, more interesting .lol
Thanks! You can like both! Lol
Well I'm glad to see that you gained 14000 subscribers in 2 days. Your channel is good as diesel Creek and I enjoy your videos very much.
We are! Penn State
I applaud your self control to not just fog the thing with ether. Bravo sir.
I try to avoid it never seems to end well
Hi Sam, I’m a new subscriber who migrated over from Diesel Creek, a channel I really enjoy. Diesel Creek is where I first became associated with your work. I’m really impressed with your channel. Less YeeHaw and more a man who truly knows what he’s about and with the patience and persistence to accomplish goals. Very nice. Very entertaining.
Love the good ol Mack’s
You and me both
Cummins or CAT... it will run.... Many may really dislike electrical, and I get it. If you want to make your life more enjoyable. Start wiring with Deutsch connector and 21st century relays. I pulled the wiring our of my brothers 79 Z28. Bought a new wiring setup. Mapped my wiring in a spreadsheet...and Deutsch connected everything. If we / he pulls the motor again four connections
Cudos for your perseverance
Thanks! this is going to be a project alright lol
Just came to your channel Scrappy. My old man Bought new Brockway in '59 , Macks cousin . It had a 220 Cummins
Hope you have yourself a high five for persistence,she’s a great lookin fb old school original so definitely tidy her up or give her a full makeover but keep the body original imo.keep up the great content Sam.from sunny (haha it’s freezing and pouring with rain & snow),Liverpool,united kingdom
Just dropping in from Diesel Creek. Subscribed and love the content.
Awesome! Thank you!
Way to diagnose......nice job.
Thanks!
New to the channel, way to keep the old dog alive!
Thanks!
Sam, I have followed Matt at Diesel Creek, for a couple of years, and saw you were helping out, and glad you guys help each other out. Now I have both of you to follow, as like me I like the older machines!😊
SEMA TRUCK, Nice lines on that. The cummins is a nice upgrade.
Just found you by. Matt. Looking forward to watching your channel. Thanks from. Sc
That 5.9 will make it a much better pulling machine!
I hope so! think im gonna try to slide the original Duplex trans back behind it
That is the low air warning buzzer. You can check with your state DOT sometimes they allow you to have a light or buzzer in some states you need both. Those buzzers are pretty rude! You can verify it if you want by using shop air to fill the air tanks and see if that cancels out the buzzer.
I was made in 1953 also, my chassis is breaking down but otherwise does funcion, had some engine trouble this year but working ok now. Enjoyed this video bro. Safe travels. Ken
Your low air buzzer still working though...?
10b hauler right there!
Bud we will be hauling a descrappin!
Wow I've been watching these videossince you started shifting that B model and it's the trip to watch you turn this thing over I'm just it's gettin late here at night but I'm still watching you turned at a model over and over and I know you've already done it that's because it's an older video but I thought I'd say I appreciate it you have a good one
Deutsch connectors take a project up so many levels in durability and serviceability
I love em- i cleaned the firewall up a lot will show in next video
Looks like a typical aircraft wiring connector.
It's an adventure stepping in where someone else left off for sure, good video.
It is no wonder that You and Matt get along. That fuel and battery setup was full on jenky, I like it as I have taught my sons the same. Also liked the music, sounded throw back Led Zeppelin.
Great looking Mack 👍
Sam you got the knowledgeable. And pattince. To go that kind of wiring .
I can't wait till I get it restored😊😊
Nice job Sam. Looking forward to seeing the old girl back together.👍👍👍
Great job great video thanks Sam
Sweet! Ya just gotta love troubleshooting! Thanks for the video.
Matt sent me over to look see,Good content. glad i came. Thanks for sharing.
Hi Sam , I come from Diesel Creek, nice restauration. Greetings from Germany.
You might have some asbestos there around the cab bonnet seal? Check it out...
Great video love the Mack's to thanks 😎👍
Thanks for watching!
well glade to see someone else likes the same lights I use .
Found you from Diesel Creek. New subscriber.. like what I see so far.. thx for the content.
Congratulations It's fun to troubleshoot franken setups
lets go Sam!! great start
Thanks Jay!
Congratulations, sounds really great !
Congrats!
You can't trouble shoot a kludgy harness for. You need to start your work with a known quantity. Start with a new harness totally devoid of cockamamie wiring. 8:58
I am going to have to thank matt for giving me a heads up about you sam.
Love the Mack.
12:40 i was half expecting to find a link to the Semi-Supervillains youtube page because i grew so accustomed to their tracks this sounded exactly like one of theirs, still a great track and glad you chose it Sam.
Lol nope just stock TH-cam music. Thanks for watching!
Well done!
Sounds good!
Years back my neighbor drove one like that attached to a cement mixer/hauler, the hood said Thermodyne on the side, what was did that mean? Interesting videos.
Nice some one with good content
Morning Sam! That's a great idea using the motor & trans from a school bus, not to excited about a auto being in your Mack, but you're going to change that out right? But.....this gives me a great idea, I know they put alot of V8 cats(3208) in many school buses, like to do this swap in my 96 Ford F350 dually pickup...
Just saw you on Diesel Creek and subscribed. I'm sure I'll enjoy your channel.
Frank Bryan green. Awesome truck
That’s going to be a cool truck.
I just found your channel from diesel Creek, looks like an amazing rebuild project. New subscriber out for now.
Subscribing after watching you work and fooling around with Matt you are a (my kinda guy).
Love that dog. Beeeutiful. Over from diesel creek
Thank you!
To. A matt and use the starter fuild..
Great vidja to boot
I'd have pulled the 24 valve and put in a nice mechanical 12 valve. Be a lot easier and less crap to go wrong down the road. Only wiring you need is for the starter and FSS. But the FSS can probably be made mechanical too.
Nothing wrong with the 24v. 12v is a damn great engine but they are definitely overrated. Put a FASS or an AirDog behind the VP and you won't have a problem. They are super easy to diagnose and repair just like a 12v
Way to go
Cut the wires to that buzzer!!!
At first i thought something might grenade in there lol
Just fill the air tanks buzzer will stop
WILL Love the way you tackle jobs, the only thing better would be you and Matt from Diesel Creek tackling impossible jobs together.
That’s going to be sweet when it’s all done. I would definitely leave the old door stenciling on that rig it goes perfectly with those great old lines.
I’m trying to do the same thing with a 53 LJ mack came factory with a 190 Cummins need help with the 5.9 bus 24 valve
Nicebb vb job. Nice truck
Thanks!
The longer, but simpler solution would be swap out the electronic fuel pump; to a p-pump. Gets rid of the computer for the most part as well. Would that possibly be a project further down the line?
Probably not because this is a 53 block. Either way swapping a 24 valve to a p pump is a big job with a lot of changeover. I didn’t buy it the previous owner already had it in there I would probably just swap in a P pumped 12 valve to your point
nice
Great video thanks from down under!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1
😮 Take some air and air your air transfer if it turns off, that was your problem
❤❤❤❤❤
When are you or are you planning on getting back to working on the Mack?
It’s on the list lol I wanna make it drive so I can get it out of the way at this point
@@ScrappyIndustries haha, my grandpap drove an R model Mack. So it reminds me of his truck just different model.
Where’s the ether?
Why didn't you use Cosby sauce to get it started?
Tho you evidently did get it started
Put the shop air in.
Sir I am from legit town and there was a scrappy s in langhorn is that the same as yours company
Have matt bring over a case of ether. 😂🤣🤣🤣
actually a little starting sauce would not hurt anything. May have started a lot quicker.
A lot of these engines had a pre heater in the air intake, starting fluid is a big No No
Every electronic diesel I own has issues of some variety. Every mechanical diesel I own wants to get up and go to work...... I know what I prefer....
I don’t disagree. This guy was in there when I bought it. I think a 12v would be the hot ticket
👍🏻🍻
Yes it's nice to have a hand full throttle crank for 10 seconds wait 30 seconds then half throttle crank for another 10 seconds it should start percolating the old secret to starting 471 a 671 and even a silver 92 Detroit Diesel they was dirt when it was cold that way probably wasn't enough fuel in the cylinders and not enough battery when you do that process the fuel will seal the rings off better and then it'll atomized better because I don't think you have enough compression to ignite thanks great video
Don't you have some. Big jumper cables made of welding cables it you do pull super dog in to jump his little brother.
You have good music,peace
What a great project!, I send you a like and subscribe to your Channel too!
It only has to work once
Those are not deutsch connectors they are mil spec cannon connectors....
Put a couple of 8D batteries on that truck and it should flip it over on it’s top 😂😂😂
I usually like what you post, but this video was very painful to watch
Can’t win ‘em all
Blue tooth drive shaft... 😂😂😂
I hate when people drop automatics and electronics into stuff like this……. Couldve just put a mechanical 12valve in it and used an eaton transmission…. And spent maybe $2000 total…to do it…. Would run with one wire….. and wouldn’t have a ridiculous shift tower sticking out of the floor
Previous owner put them in. I am am going to change the transmission but I don’t mind electronic engine. You can build yours however you like.
25 mins in and no ether . What gives ? 😂
no fuel
It’s automatic 🤦🏼♂️🤢🤮🤮🤮🤮that’s terrible
