When you do a repower, often the PTO end of the crank is a different diameter on the new motor than it was with the old.  These electric  PTO clutches should be pretty much the same whether they come from a Wheel Horse or an Ariens or a Grasshopper, right?

If you order "the" part number called for in your tractor manual you will get  one made for the original engine. Is there a "standard" brand on these clutches?  The tractor makers did source these from an outside supplier, right? 

so if I pull an engine with say, an 1-1/4" PTO and the replacement engine has some other size can I just order a new clutch (or hub) to match the new engine's PTO diameter?

PTO clutches usually come from Warner or (if you are particularly unlucky because of price) Ogura.  The almost all interchange. 

 

There is no reason why you can't use a different clutch to match your crankshaft.

that is easier to deal with than the other way around---replacement engine shaft bigger than original engine.

Is there any way to test an electric PTO when its not on a machine, I have one that I believe is off a Bolens my Dad had and was told it was good... I'd like to sell it but don't want to send someone a piece of junk

Aren't the electric clutches the same thing used on car and truck air conditioners?

basically same idea but "the same"? no.  A car AC pump gas a smaller diameter and I have never seen a car's A/C compressor shaft protrude through the hub like these would/
