Will it START & DRIVE? V12 Supercharged 2 Stroke Detroit Dump Truck SITTING for YEARS

In this video, I go back to the 12v71 V12 Detroit Diesel 2 Stroke powered Wabco Haulpak Dump Truck. I go through the motions after freeing up the injectors in an earlier video to see if I can get it to start and move after it has been retired from its duties in the quarry more than 20 years ago and left sitting in this paddock in regional Australia.

This big V12 Detroit diesel is fitted with a mechanical roots style blower which can be seen on the top of the Detroit 2 stroke engine. In Australia, many folk would refer to a mechanically driven air blower device like this as a supercharger. In this application, its function however is not so much to force “boost” into the cylinder but to use the air pressure generated to help blow away exhaust gasses.

These 2 stroke GM Diesels or Detroit Diesels can be found fitted to all types of heavy machinery, transport and marine applications over about a five decade period. Despite this, they are becoming less and less common and should be preserved where possible in my opinion, hence attempting to bring Wally Wabco back to life. Thanks very much for watching.

    My dad was a heavy equipment mechanic on a surface coal mine. The man could fix anything. He's been gone a couple years now. But these video make me think of the days I went to work with him when I was a kid. Thank you.
  • Love watching this guy mainly because everything he does on any mechanical part it’s done right, When I was learning to maintain earth moving equipment and weld and fabricate, I was told by all these guys if you are going to do anything then there’s only one way and that’s do it the correct way, Great show as usual 🇮🇪🇮🇪🇮🇪

    Thank you for taking the time to save the truck. It would be a shame to see it turned into scrap.

    Never had a doubt it wouldn't run but it sure has led a hard life. I drove the old Euc R-35 about that size with the V-12's and they were a strong rig. The quarry had an old square hooded 980 loader with that same brake system. They had to re-do it all because it was supposed to use 5 wt. oil instead of brake fluid. And to haul those trucks they'd load them and then remove the front tires and set the front end down on the trailer frame to get the front end down. Keep on getting greasy Bruce and will be waiting for the next one! CHEERS!

    Your doing a great job Bruce! Something sitting that long outside is a real challenge to get going! Thanks for your hard effort 🤙🤙

    Look at this guy go. This fella is working on something from the 70s and just the other day I was told by a local mechanic that they don't work on trucks as old as mine is and it's a 1992. Just don't think these younger mechanics know how to work on anything old and I think that's really sad.

    There's something immensely satisfying about seeing a forgotten workhorse like this being brought back to life in a fastidious and patient fashion! Also its a great tribute to all that were involved, from the people that built it in the factory to the people that operated it for many hours to build a business. Good onya Bruce!
  • @glennfryer1539
    Great video Bruce...at least the old gal moves, looking forward to the next one....regards UK..
  • @albertohart5334
    Awesome to see this, even more awesome seeing SE Qld content, like it’s been raining on and off for about a week here I’m guessing this must have been filmed at least several days ago
  • @connorwhite2745
    Great video, had a funny thought, in Australia we still say mileage though we use kilometres,
  • @Hungry_Hunter
    All that oil and hydraulic hose would have cost a pretty penny too. Really enjoy watching your work. Nice one maybe a tripod is a good idea for Xmas.
  • @roberthevern6169
    Did he say Wabco? If so, the 'haul truck' was made by Westinghouse Air Brake Company. Wabco developed the air braking system for trains in the steam era and continued on into at least to late 60s if not further! They were 50yd haul trucks! As a teen I watched these come into our 'yard' on flatbed rail cars with the dump bed separated and on its side, due to the excess width. Cool to see one 50 years later on another continent!!

    I’m new to the channel Bruce and I’m now binge watching the whole lot. By a country mile, my new favourite channel. I love the way you do things without hugely expensive tools, brand new service trucks and all the latest and greatest. Shows your knowledge and the proper way to do things. Keep it up mate. I love it.

    I'm a simple man. I see a proper job, I upvote. Can't wait for part three. Greetings from the Netherlands
  • @latemcire8387
    Great video! Looking forward to seeing it moving again
  • @grindcorgz
    V12 2 stroke? That's bloody amazing 😂
  • @paninaro-zq9hx
    Legendary dude, old school, I met these guys when i was in my 20's which is 40 years ago now, engineers that could fix anything.

    I'm only here for the dump truck! The A.I. algorithm knows what I like (old and abandoned equipment). It's what most people would deem to be a lost cause *especially due to the massive size*. You've got a winner here with the previous hour long version at 1.5 million views. Would love to see more videos just on this lost and forlorn old dump truck. Love the production values, the clip-on microphone so we can hear it all and the camera-man is top notch.
