Pulling Off The Fly Wheel On Ty 80?

Featured Replies

Any Ideas on taking off the fly wheel on a TY 80 if I do not have the specific Yamaha, puller bolt, extraction thingy? ;)

A pully puller I imagine could damage the flywheel?

sam

you need the right puller, can damage the cases or the flywheel.

It is a generic japanese, 27 mm LH thread if I recall correctly.

Dennis Kirk has them maybe $15 or 20.

You may need a spanner to hold the flywheel from turning also, I made from a bar stock with some pins. Also made another one by welding bars onto an old vise grips.

My latest problem!

I have removed the flywheel on TY 80 and it has had a lot of corrosion/rust from mositure.

With a tight flywheel spinning, no spark, but if I pull the fly wheel off the shaft a little ways then it begins to spark very well! I have lightly sanded with black fine sand paper some of the rust off the point of contact on the flywheel where the points arm rides, still no spark.

Any Ideas?
