Removing a centrifugal clutch

[cunhab52]

I have a single cylinder Wisconsin with a 6" centrifugal clutch on the 1" shaft.

The outer drum was attached with a C clip and came off fairly easily.

The actual clutch is a different matter. I do not see any set screw holding it on the shaft. There us a keyway on the shaft.

Rear plate is too thin for a three jaw puller and I can't get a bearing puller behind the clutch.

I don't know if the C clip that holds the outer drive on the clutch is strong enough to pull the clutch off the shaft.

Any thoughts on how to remove this?

I guess it could be threaded but doubt it, probably a "slip" fit that has gotten plenty tight over the years. I would find something to slide behind the clutch and hang the motor a 1/4" high then get out the oxy acetylene, heater up the outer bushing and tap the crank shaft down out of it.

Heat and a air hammer

Heat it very hot then freeze it (or at least cold water) that should partially break the rust connection a bit. Then heat again. Press , A or H type would be best( hate pounding on end of a shaft ) if you can get some steel bars in between . There are bearing removal units that are 2 tapered sliding plates ( wedges) that have bolts through the sides as you tighten them, they side together in theory causing the parts to separate - much better than any jaw type puller
