Motorcycle Repair: honda s90, honda s90, flywheel puller tool


Question
QUESTION: Hi,
I'm rebuilding a 1966 Honda S90 motor and can't seem to get the rotor off
the engine. Manual says to use a puller. It seems to have a taper shaft and
key way so a puller appears to be the correct tool but I've tried with three
different pullers and it will not budge. Any Suggestions?
Thanks
Mike

ANSWER: Mike that's the right way to get it off.  Put the puller on and tighten it up and then tap the end of the puller with a hammer.  It should pop right off.

QUESTION: Hi,
Thank you for the message. I did try your method of tapping the end of the
puller but I had no success. I think there is a special tool that screws into
the rotor center and then has a T-handle threaded center that forces it out.
Much like a puller but concentrating all the force on the inside. The puller is
grabbing the outer edge and since the rotor is built up from plates, the force
is not centralized. Anyway, I have two engines and neither one will budge.
Any further suggestions would be appreciated.
Thanks
Mike

Answer
Sorry, I mis-understood.  I thought you were using the right puller. I've not had a lot of success using a puller that grabs the outter rim of the flywheel but it would probably put enough pressure on to break it loose.  If I remember correctly that flywheel had a large thread for the puller so the rear axle won't work.  Several of the Hondas could use the rear axle as the flywheel puller tool.  

Your options are to get the right puller, or use the three jaw puller and whack it harder with a steel hammer.  If you are using a deadblow hammer, it won't break it loose.  Sometimes it take several hard blows to get it to break free.
