Title: Flywheel Removal RM400N
Post by: Toolboy on June 09, 2011, 04:07:48 pm

Gday all,

Im having a bugger off a time trying to remove the flywheel on my RM.

I have bent  my bolts on my pulley, tried to jar free with hammer taps??

So has anyone out there had any success or some tips on a good way to remove with out destroying the flywheel.

Thanks

Tim

Brother   "Mutch " had the same problem with his a few months  back, got it in the end by using a bit of heat from memory.

Yep i had the same problem,ended up buying a puller set from from engineering shop but had to modify it so it would hook under the flywheel.
I used a propane burner around flywheel for about 5 minutes then mashed the top of the puller with a heavy hammer.
Hope this helps.

Have you tried one of the K&N pullers that uses the 3 bolts to screw into the flywheel ?

Amazing what a difference an overnight break makes..

This morning i tried again to removed the flywheel and with 2 hits of the hammer whilst under load from the puller the flywheel popped off,,,,easy

yeah  ;D

Thanks for the input guys... now i only hope my RM370 flywheel pops of the same but a little easier when i split.

The way I've always found best is to use some high fast heat if possible, and then quickly undo with a good air-rattle gun on your puller bolt. Then cool off things with air, or wet cloth.

I often find if you have a really stubborn part to remove returning to it the next day and it will come apart easily, I have just removed the flywheel on my Stormer that just would not move (self extracting nut) Left it under tension over the weekend, a couple of taps and bingo! It had actually corroded on.
