Cb550 k3 primary chain
McCabe-Thiele (Ted):
Gawd stripped rotor threads - a bit late in the day now - my experience with most similar pullers is to just nip the thread up so it's in place but not over tight. Then a good lump hammer strike on the top of the puller. If it does not budge a little more nipping up and repeat. Using a big bar or an impact gun on a puller is a no-no for me. I've had car flywheels and all sorts where the taper surfaces have part fused but they have always come out.
With the crank out you should be able to apply some impact force from behind to get the rotor off - one side then the other with a helper holding the crank vertically if heat alone does not work.
Keep us posted with your progress.

I’d strip the motor then go for the rotor later. I’ve found that it’s easy to use judiciously placed soft wood and progressive taps with a hammer will ease it off. Worked for me as I didn’t have a puller.

Trying to get the rotor off the crankshaft I screwed the removal tool into the rotor, First tried with a crack bar but no joy. Then I used an impact gun, still no joy and the threads have stripped on the rotor.
Will I damage anything using heat?
Any other suggestions welcome.
Thanks Ian

Paul Gledhill lives in the Sheffield area, he has a lot of experience and may have a puller. If using a puller, always place a nut in the hole so, not to damage the crank thread ;)
