Sunstar Electric pto clutch options?

[SmilinSam 4,031]

"Borrowed" a real nice K341 16hp out of a cheap craigslist Deere 316 for my single cylinder Sunstar as a replacement for the tired 14 in it.

I dont know that I will ever mow or blow snow with it, but If I should like to I will need to do something about the electric clutch. The 16 has a 1" diameter pto shaft and thats a problem when the clutch on the 14 is for a 1 1/8" shaft.

Can one use a bushing to bush the 1" shaft to 1 1/8" and have things work right? If not, is a double pulley clutch like a Sunstar uses available for a 1" shaft ?

I would yhink that you'll be a 1/16" in short in the keyway, you'll have a 3/16" X 1/4" KW engagement rather than 1/4 X 1/4. And I think, you'll need to make an adaptor between the clutch and crank radius end near the seal.

What about one of these?

Would that be a good start?

I would think that adapter would work fine.

My son replced his clutch a few years ago on later model SS, 1692135, CH 20 powered and forgot this spacer between crank and PTO, installed PTO, started engine, flipped switch and seized engine, called me panicky to what happened. After going thru stack up, he forgot spacer and went to remove PTO. That took him a while, but he goy the spcer installed and everything went OK. Might not be a problem with you but need to tell you anyway.

I'll look it over real good after I get the engine swapped in. Looks like I will need to bevel the inside edge of any spacer I might need.

The 18 hp sunstar with a briggs engine came with a pto clutch with a one inch i.d. The parts number is 1714637. I bought a nos clutch on ebay when the one on my 20 hp kohler allis 1920 locked up the bearing. Didn't realize that it was too small till I received. There is a used one on ebay but they are rather proud of it....

Would you then run a single belt Sam, or are the single cylinder Sunstars a single belt setup?
