Thought I would post some ways to get the clutch off an engine. Most of these ways would require the engine to be out.
--I have a 3 to 4 lug adapter which was almost the same exact size bolt pattern but not 100%. It was close enough to work but would feel better probably making my own puller plate if I do it again. Just make sure the 1/4"-20 bolts thread in a ways so you dont yank the threads out. The newer shiney gizmo came in the slide hammer set. I found a nut for it but it wasnt a common size. I could describe it all but the pictures pretty much tell all.
--You could make a plate the adapter I was using but threaded in the center hole. Run a threaded rod in to the crank pushing the clutch off. Just be careful of the crank and threads in the crank.
---Another method I have done and thought it was funny when I found out someone else was doing it. (evil8x8)
Hang the engine by the clutch. Use board and put them between the faces of the clutch and let the motor hang down. Thread the clutch bolt in the crank but not tight. Leave a little gap. Hit the bolt which pushes the crankshaft out of the clutch. I have ruined the clutch bolt doing this though.
There is probably some fancy clutch puller for these clutches too. These dont have the internal threads like other clutches have.
Gear pullers on the faces seem to always crack or warp the inner face near the engine side. You need a huge puller too.
Before reinstalling a clutch, run the engine and sand the shaft down a tad. Dont do that on tapered shafts though. Just the straight shaft engines. That will take some tolerance out and make it easier next removal time.
Hope this helps!
