Hi Jimmeh, Welcome to GTtalk. One of the members will be along before long who can help you.

Welcome to the forum! Never have done many modifications, but I'm sure someone here has.
How old is that Waukesha? I see it has a Fairbanks on there, it has to be older.

Welcome to GTT. What is wrong with the differential that is in it?
I have a homemade tractor with an ICK for the power. My FIL built it 50 years ago. It and the two spare engines are siezed. These engines go back to before WWII. They were even used on some bombers.
Where are you getting parts for the engines? A large frame Bolens could handle the power better. Good Luck, Rick

MMMM! ? Think your NUTS! Would need a bigger tractor chassis than that for me to start building it. Might look into a bigger Power/King or ?? OR, make your own frame and find bigger parts to go with.

I'm afraid that chassis, unless all you plan to do is sit & show it....it just won't hardly stand the weight of the engine sitting, much less running/using it. The steering system in this GT will never hold up with that kind of weight on top. As said, better to find a heavier chassis before going further. Kind of like eating, ya have to keep an eye on how much you bite off or you might end up with a sick stomach. I'm not trying to be a downer on the project at all, as I like these kinds of projects, and will be following it.

Take a look at the Panzer diff. You'd have to buy a rusty torn-apart one just to get the rear diff being a narrowed plymouth rear end. You'd also have to gear it down. The panzers use a #50 chain and sprockets to gear down 6 to 1. Gearing it down to the right number would be the tricky part. How many RPM does that engine turn? If it's 3600, then your entire drivetrain needs to gear down about 9 to 1 before it gets to the differential to go at tractor speed.
Just for reference... 1 to 1 would be a car in high gear. I'm using a power king tranny to gear down to my panzer. All custom fab stuff, but a power king tranny is rated up to 50hp as well.

My FIL got a bunch of these engines when the company he worked for converted their big Waukeshas to air start in the 60s. He also got a bunch of nos parts for rebuilding the engines. My bil let the weather have them. Such a waste.
Can your friend supply an address for ordering parts?
The more I look at what you are trying to do, the less I think that it will work. Its kind of like putting a good american v8 in a Yugo. It may run for a little while but, shortly the rest of the vehicle will fall apart around it. Look for an older large garden tractor that can handle the weight and horse power. That way you are not wasting your valuable time. Someone here stretched a large frame Bolens. The chasis can handle the weight and the transaxle is rated for 35 hp. I have 70+ little tractors and my large frame Bolens are my favorites. They are bigger than most GTs. Look in our gallery for pics of the various types. Good Luck, Rick

ive taken time and thought through this.
im going to run this til it dies then get the heavy tractor. i cant find one around here to save my life.
i got the clutch and gear box mouted on the engine and the rear axle from the craftsman flipped so the input shaft is facing the output shaft of the gear box.
one drive shaft and some linkage away from comical mechanical mahem.
