Cobbled mini atv clutch issue

[BuckthornBonnie]

My buddy grabbed a cheapo atv with problems. Someone chopped up the frame and put in Briggs 5.5 ohv. It runs (thanks to carb rebuild, oil change, valve adjustment) but the clutch is fried.
It’s a keyway clutch shaft (not a spline) that is 14mm at the end. The original clutch shoes/pads are shot.
Is anyone into these things? Any options to make an eBay clutch work?

Check out comet industries, they are a leader in CVT clutch manufacturing. They make clutches from go carts to snowmobile and ATVs.

Will do, thanks for the reply.

Check with Northern Tools also, they sale stuff like that also.

K, thanks for the heads-up!

I had one of the 5hp go carts with the comet. They work very well. My son drove it into the ground and it would pull us both around without issue. They're so cheap on ebaeit makes me sick after rebuilding an original...

I may have to make a sleeve to deal with the oddball crank size.

Try BMI kart also.
Is that the shaft the clutch was on? On the jackshaft, not engine crankshaft?
When I was racing mowers there were 2 different classes that allowed centrifugal clutches. Some guys ran them on the crank, some on the jackshaft.

Comet Kart or EC distributing could also likely come up with something, but the clutches they carry are meant for more HP, and not cheap.

Yep, the clutch was on that jackshaft. Good to know about other options.
Yeah, this needs to be a cheap fix. It’s already cost a lot of time just figuring out what the heck it is (still dont know brand or anything). It’s pretty much a death trap...

 

[BuckthornBonnie]

No dice on any current production clutches fitting. Looks like we’ll need to make a sleeve or try to repair the old one. The shoes are totally shot, though.

Couldnt you just use a different jackshaft? As long as the o.d. of tbe bearings are not some strange size, new bearings and a normal diameter jackshaft should cost too much.

You can see if you can find a place that still relines brake shoes in house. They may be able to rivet on new material
