snow moblie torque converters

[kayde]

He guys im goofing around with a few differnt projects at once.

I have a manco ez rider to build for myself and im hoping to use a 12 hp ohv briggs clone style engine with a 1" pto .

I have a 30 series comet setup but im reading that its too small for it.

I found a parts sled with a complete comet 102c driver and driven.
I have no idea what kind of sled it is.

Would the 102c work on my 12hp engine and be ennough to handle a larger engine in the future?

Not likely. The driver shaft is probably different, the driven shaft is probably splined, and snowmobile engines (depending on the sled) can spin 10,000+ rpm, which means even with no governor, it might not even spin the clutch fast enough to engage, let alone ramp up to high gear.

On the other hand, it might work. Maybe. But probably not real well.

I would almost guarantee the driver has a tapered shaft.

40 series should do the trick.

Thanks guys,
Ive been looking around for a torque converter that might handle any future engine upgrades and thought that 102c would be it.

Like most of us this is something i only want too buy once. And since this cart is for myself its gonna get used hard and i was hoping to get a tc thats bullet proof.

I got this ez rider dirt cheap with the separate 12 hp briggs
They had it running and riding but cracked up the swing arm so they pulled it all back out but left it sit.

I got the briggs purring again on the bench and now its time too do something with this swing arm and weld some gussets in other areas.

Theres no jackshaft for it so that gotta get figured into the plan.
They have this homemade jobby splatterd on the swing arm but doesn't look like something i would roll with.

We ripped around on the little red fox a few nites ago and got me itching to get this one together.

Comet 780 (if I recall correctly)

1" keyed driver, 3/4" keyed driven I believe. They're not cheap, but they're the next step up from a 40 series. Rated for 25+ hp

Thank you!
I read a little bit about the 780 seems like a very likely option.

I tend to cross paths with all kinds of stuff.
One of the sites i read lists a few machines the 780 came on so now i know a few things too look out for on my search.

I gotta draw up a plan for this swing arm.
The center pivot mount on the frame is cracked already and it just dont seem very strong.
