Yerfdog 3203 Axke Setup

[Mrmonk7663]

Hey guys. New here and looking for some help. I just picked up an old 3203. It was in sad shape but I’m brining it back to life. The wheels were seized to the axle, along with every other component. I cut it in half and am starting fresh. So my question...per BMI’s advice I purchased a 40” axle which is keyed the entire way. It has no snap ring grooves to locate anything, unlike the stock Yerfdog axle. Here is the plan and please let me know if it will work or I need a different idea...

Center axle. Place a locking collar behind each wheel with a washer to locate the wheels. Place a locking collar on either side of the brake drum to secure it. Sprocket has 2 set screws in one side, so place 1 locking collar in other side. Place locking collar on each side of the RR bearing, and one locking collar on LR.

Will this work out fine? The wheels, drum and flywheel will also have the 1/4” key in them obviously.

2nd question...the predator 212...does it bolt up exactly like the tecumseh or does the engine mounting plate and jackshaft plate have to be modified. Does the standard comet clone torque converter bolt up like normal or is something else needed? I have the old tecumseh and original comet, but I also have a brand new 212 sitting around. Cheaper to use the 212 than to fix the tecumseh.

Thanks a lot!!

Hello and welcome,
ya using shaft collars are a good idea to secure the axle items.. its what I do on my bike..
After setting all the positions,alignment is good, making things spin free and no binding... use Blue loctite(NOT RED as that is more of a permanent) to secure all the set screws...

Awesome. I figured it would work this way but just wanted confirmation. Thank you.

A work in progress but it’s coming along. I grinder/sanded the entire kart and installed diamond plate floor which is a little thicker than stock. New a-arms and spindles and new bolts everywhere.
