I have not done anything else other than crank down the gear puller only to have no progress on the pulley.  Any suggestions? Sawzall or dremel and cut the stupid thing in half?!?

I've had luck with mapp torch with wide pulley. Have pressure on puller and just heat in the valley of pulley along the key-way only. Doesn't hurt to have some ice cubes to keep shaft cool.

I'll second this. Even better if you can use a rosebud tip on an oxy-acetylene torch.

My repower helper has a torch and I need to get out and visit with him.  I know he is excited to get working on this.

As long as the job is done, and no one is hurt, I'd call it good!

I really hope to get this off today so I can try the K series PTO clutch as an option to getting an adapter for the Onan clutch.

So I have compared the K series and the Onan PTO clutches to the Vanguard block. There are holes for each design so either will bolt to the block. The challenge will be spacing to get the pulley location on the crank in the proper location. Here are my thoughts so far...

K series PTO clutch is a direct fit to the crank but the wiring is different and would need to be adapted to the wiring of the 318.

Onan clutch needs adapter to fit 1" crank but is a direct fit to the wiring harness.

I think I will stick with the Onan clutch and work on finding a crank adapter - 1" to 1 7/16"

I had  a chanceto pick up an Onan twin a year ago for free, I snoozed and lost out but I'd have had to go the "other' way on a PTO adaptation  either find a clutch to fit a 1-7/16 shaft or yank the crank and have the PTO end machined down skinnier....

Part of the reason I am going with the Onan clutch is that it looks to be in better shape than either of the K series clutches that I have.  I really don't want to replace a clutch in the near future after all of this work.  I thought about mix-n-match with parts from both Onan and K series clutches but that leaves me with useless parts.
