Removing Flywheel

[86KAWIJS550]

Does anyone know how to remove the flywheel on an 86 js550. I took the cover off and got the bolt off, but the actual flywheel will not come off. I've pulled, twisted, and tapped it from behind with a hammer; with no avail. I read in my Clymers manual that you need a "Flywheel Puller" but in the past, it would just pull right off.

Thanks

need a fly wheel puller... you can get one at harbor freight for cheap. it shouldnt just "pull right off"

Re: Removing Flywheel

I got a flywheel puller, but when i connected it on the flywheel i cranked it down and it isnt coming off. It cranks down to the point where it will spin the drive shaft... not sure what to do now. any thoughts?

i used an impact guy to tighten it really good. then smack the end of the puller with a hammer. it will pop off

Re: Removing Flywheel

Try some propane, or map gas heat just around the base of the wheel....near where the crank is in the wheel. Don't heat the crank, the metal of the wheel, and not to long, maybe two minutes...then hit the tightened puller end with a dead blow or brass hammer. Also, it is critical that the puller is on 100% straight...that is a key to an easy pull.

Re: Removing Flywheel

I have tightened the puller as far as it will go, and now tried hitting the end with the hammer. it is still stuck on there. would you suggest using like a propane torch? and heat what part of the flywheel?

Re: Removing Flywheel

stand the engine on end "flywheel up" remove your puller, heat the threads, then apply wax "cheap candle will do" sometimes this works like a charm. the wax will work into the threads and free them.....

what kind of flywheel puller are you using?? use shorter bolts to bolt it to the flywheel. that way you have more threads on the part that tightens the puller.

you really shouldnt need heat. just a 5 lb sledge and use the puller correctly.

obviously the flywheel is not threaded on. When you heat the flywheel where it is pressed onto the crankshaft then dab the candle on it, usually it will allow the wax to work its way into very small gaps "in between shaft and flywheel" allowing it to break free.....

I use this method on rusty or frozen nuts and bolts all the time and it works great.

Maybe the guy working on the ski getting his hands dirty will understand. I am not a proffesional internet mechanic, just trying to pass on a little trick that i was very surprised with.....

Re: Removing Flywheel

i thought you said it would get into the threads. i know what your saying though.. he should be able to do it with his flywheel puller. sounds like he is maxing out his puller. shorter bolts should fix that. i see what your saying about the wax. i have used that trick on the coupler

Re: Removing Flywheel

I must not have the right kind of puller, I got it at the auto parts store, it has 3 hooks that grip onto the flywheel and a center bolt that presses onto the shaft of the crank. not sure if that is the right kind, it is by no means the factory Kawasaki puller.
