Thanks so much for this information. The official work begins this weekend when we roll her into the shop. The "crew" is ready to get that Thermodyne running!

The serial number falls right in the middle of the ones posted in the registry as 59 so I'm assuming mine is a 59. Mine has the same hand brake and fuel gauge as in the quote but a stamped steel brake pedal Quote Link to comment https://www.bigmacktrucks.com/topic/63676-new-here-b60t-project/page/2/#findComment-462082 Share on other sites More sharing options...
Maddog13407 Posted October 8, 2020 Share Posted October 8, 2020 59 or so was the 1st year for the stamped brake pedal give or take. the old cast ones actually use to snap off 1 Quote Link to comment https://www.bigmacktrucks.com/topic/63676-new-here-b60t-project/page/2/#findComment-462090 Share on other sites More sharing options...
SkippyMack Posted October 10, 2020 Author Share Posted October 10, 2020 We are wondering if these trucks are usually 12V and negative ground? Pulling her in the shop this weekend!

SkippyMack Posted October 13, 2020 Author Share Posted October 13, 2020 Got the truck in the shop over the weekend. Tonight we got her up on jack stands, took off the wheels and got to work. Our understanding is that the truck had run within the last handful of years. No reason not to believe the person we bought it from as we have a good working relationship. Someone had done some work in recent years (evidence including fresh fluids, spark plugs, etc..) but it had been outside exposed to the elements when we purchased it. Tonight we confirmed that the air system can hold air with just some minor leaks (still all copper lines) and we managed to get all the brakes working! Oil is clean and good. Coolant in the block and radiator, drained a full 5 gallons. Tranny fluid clean and good. Everything looked promising...but...engine is stuck. Won't budge. 😳😖😳 Ughhh...not what we wanted to find. When the guys turned the crank with a bar on location before I made the purchase, we think they might have just turned the nut (of course couldn't really see by the radiator and shroud at the time. She's not budging. We've put Marvel Mystery Oil down the cylinders tonight. Advice?? Anyone had experience freeing up an old Thermodyne 540 (?) (Is this the only option for the gasoline engine in this vintage - mid to late 50's?) We removed the governor from the passenger side of the engine block (was next to the carburetor). That was free, not bound up. Let the MMO work? Hate to break into this block without a rebuild kit. Thanks in advance for your ideas. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/63676-new-here-b60t-project/page/2/#findComment-462313 Share on other sites More sharing options...

mrsmackpaul Posted October 13, 2020 Share Posted October 13, 2020 A lot of people make up a tool out of a old starter motor by welding a bar to the armature or shaft of the starter to put a lot of controlled force on the motor Or using a pinch bar on the ring gear if you have access Or chuck the wheels back on and have it in top gear and just tow it and drop the clutch Paul Quote Link to comment https://www.bigmacktrucks.com/topic/63676-new-here-b60t-project/page/2/#findComment-462321 Share on other sites More sharing options...
Popular Post SkippyMack Posted October 13, 2020 Author Popular Post Share Posted October 13, 2020 Good news! We put a big bar on it last night and ratcheted pressure on it overnight and let the Marvel work. This morning it turned over (by hand)! So now...do we have to put the governor back on, or will the truck run without it? 2 1 Quote Link to comment https://www.bigmacktrucks.com/topic/63676-new-here-b60t-project/page/2/#findComment-462323 Share on other sites More sharing options...

SkippyMack Posted October 15, 2020 Author Share Posted October 15, 2020 Good News: We got her running tonight! Enough to feel confident about proceeding with the project. Wondering if anyone knows about or has exhaust and intake manifolds for this engine?? Both of mine are cracked. My husband is a master welder and welding instructor and isn't confident that they can be welded. Here's the gallery I'm building of our progress. I'll upload pictures from tonight sometime tomorrow. https://sjcreativevt.pixieset.com/skippymack/ Thanks for the lead on spark plugs @Maddog13407!

mrsmackpaul Posted October 15, 2020 Share Posted October 15, 2020 How bad are the cracks, a photo will help Inlet doesnt get very hot so maybe just grind it out and use some 2 pack epoxy to plug up the crack, it only has to be air tight The exhaust if it was mine and I couldn't find a good manifold I would just make a header up for it, probably in two bits because the motor is fairly long Or find a good manifold, we never had many petrol Macks in Australia,Im guessing the State's is different but manifolds seem to be a weak point in the U.S., guessing the extreme cold and the heat dont help Good look and I enjoyed looking at the photos Thank you Paul 1 Quote Link to comment https://www.bigmacktrucks.com/topic/63676-new-here-b60t-project/page/2/#findComment-462422 Share on other sites More sharing options...

SkippyMack Posted October 21, 2020 Author Share Posted October 21, 2020 Friends, I need an exhaust manifold for the old girl. All of the flanges are broken. Not repairable. Can you direct me to a source? My husband is a skilled fabricator, and we're brainstorming alternatives, but the real deal would be a lifesaver.
