Repower 520HC with Predator 670 v-twin - PTO Clutch Question

[twin520 0]

I'm in the process of re-powering 520HC with Predator 670 v-twin.
Looking for input regarding what specific electric PTO clutch others have used
and where to get it. I have the crankshaft bushed out to 1 1/8" diameter, 
the tractor drive pulley mounted and up to 2" of free crankshaft and with the 1/4" key-way.
Also note the main load is the 60" mower.
Thanks for your help.

I have no experience in this conversion, but would think the PTO assembly from the Onan should fit the Predator.

I would think that any electric clutch from a  should work. Most should be set up for 1 1/8 keyed shaft. 

 

Electro 12 for example.

I believe the predator has a ball bearing supported crankshaft.   The manual PTO should work.
