I need remove the clutch assembly on my M20. The problem that I'm having is the threads on the ID of clutch enclosure are stripped. When I put the removal tool in and try to pull the clutch assembly off, the tool pulls out due to the stripped threads. Is there a way of removing the assembly with a puller or another method without damaging it?
You can get a three leg puller behind the clutch sleeve once the rest of the clutch is removed...
I had to grind the ends of the legs down quite thin to get them in but it does work...I put a 1/4" bolt, with the head countersunk, into the main shaft as a 'seat' for the end of the pullers threaded centre screw....Ian
In the box of "special tools" are socket headed cap screws for Just about every shaft that a puller has to bear against.
This protects the shaft and also seats the puller really well.
On the few places when socket headed caps are not available I got a high tensile bolt & center drilled the head to do the same thing.
And remember a puller is not a puller.
It is a preloader so when the bolt os given a sharp tap it is jolted free from the taper.
