Flywheel removal,85 GS750

[Guest]

Having a heck of a time getting the flywheel of the end of the crankshaft on my 85 GS750.Need to get it off to fix my starter clutch.Will button it up and order a puller if i need to,thread size is 14mm.

So you've tried threading in 14mm bolt till it hits crank,tap on bolt,tighten some more,rinse/repeat till rotor falls off taper?

After looking at the manual again I can see they want to get something to attach to the outside threads.Can't do that today so she went back togetherYes I cleaned out the flywheel.

Anybody know the thread size for the flywheel?

Nobody knows the thread size?

Apparently not! What is the external diameter ? 32mm?
Plus, I thought only the bigger motors had this external threaded hub. My 650 has 16 mm internal.

An old trick on the 8 valve was using a slide hammer with the swing arm bolt that screws straight in the centre hole. Of course there's always the correct tool which can be found on fleabay

I didn't think to put the caliper to it

No internal thread on this flywheel,#@*& *&#@#&$%^ %$*#*!

You need to get a puller and an impact.
I do believe that that is a small end crank.
It is a 35mm x 1.5 thread I believe.

I suppose this is a Suzuki only thing and I need to buy a Suzuki specific puller.Any leads on where to get one?I have an impact.

This is quite the tool! I'll bet you can find other uses for it- tenderizing meats maybe!

Fits a few other bikes,maybe my local dealer has one I can borrow

[SVSooke]

He does and I can,a big hand to Ken at Kenco

if there is no internal thread what actually holds rotor onto the end of the crank

Don't worry,there's still a bolt into crank end that holds rotor on taper!
