212 Golf Cart

I know this has 4 wheels but the build is in the spirit of what we do here. A friend gave me a fairly nice Ezgo cart that needed too much
to repair the electrics. Having a new 212 and torque converter in boxes its a no brainer. About a zillion of these have been done, but as usual
I opted for the hard way. Not wanting to build all the intricate structures most folks do I opted to use the case of the old motor. Required a lot of tedious, actually a little over an hour, cutting of the motor case. With the case opened I can run a drive shaft inside the case turning the original input shaft with Lovejoys being driven by a a chain from the Preddy. This keeps every thing in its original places drive wise. Much less complicated fab wise. And yes thats 1/2 steel I cut and hole sawed from the case. Speed calculations indicate a pretty good top end.

The brush holder now holds a flange bearing to support the shaft on the other end. Just waiting on Lovejoys now. Ignore the rusty parts, they will be handled.

Got the 212 off the shelf and opened it for the first time only to find out its a dang hemi. I prefer the old stamped valve
cover model. This means no electric start in the future. I believe It takes Kohler compatible parts to convert it which are $$$. I watched a youtube vid by a guy that used the 212s as replacements on his equipment. He found the hemi more problematic than the old model. For guys racing the hemi Im sure they correct any issues. Its a very nicely finished engine, but I prefer the old model. Oh well gotta run with it.

Cannonball3 when you have time, would you measure your 212preddy intake manifold bolt pattern center to center in millimeters. I'm curious as if the 212 hemi intake pattern is the same as a 5hp flathead briggs. Thanks!

Some more progress. I imagine most folks have little interest in this thread, but there may be a few who
would benefit from the info down the line. Got most of the conversion roughed out. Finished the throttle control, drive line fab and exhaust. The charging system will be mounted on the right rear side of the engine and belt driven off the torque converters reduction shaft. Dont have the parts in yet, but should be fairly easy. Waiting on the engine mounting plate so its all just sitting in there in the proper positions. Maybe next week will see it up and running. Anybody see the BluevHeeller?

So on the predator, you got to drive you charging system on the outboard side of the torque convertor? Due to ohv engine block being in the way of the inboard side of torque convertor? I like this kinda stuff, it's what drove me over the edge on the Rollfast belt drive bike.

Actually its on the recoil side(right) because there is a lot of dead space there. I bought a 16” piece of keyed 5/8. Its long enough to drive either side but the converter side is pretty crowded. I have in the past run sprockets outboard of the converter and also on the inboard side of the converter. You are limited there to smaller sprockets. The converter is pretty modular and can be configured many ways.

Briggs 5hp raptor??

Is there a reverse on your diff?

Is there a reverse on your diff?

On a electric cart dont they just reverse the polarity in the motor controller to reverse the motor direction? I'm curious too!

[Greg58]

Yes, usually at the directional switch. When I was working in that field we used to test motors on 12v, put a jumper from either A post to either S post and hook a charger to the other posts, reverse the cables and change the direction of rotation.

Is there a reverse on your diff?

No, gotta push it backwards. Fortunately is pushes real easy now that its so light and its flat in this area. My old 80s
Ezgo with the Robin 2stroke ran backwards to back up. When you threw the lever to reverse, the entire magneto plate
rotated to run the other direction. I assume the starter/generator reversed also.
