Impact and no piston stop. Just hit it quick and let off.

tried that

For ones that didnt come off like posted above by Mike. I used PB Blaster let set over night, sprayed a couple times hours apart. Then next attempt next day bumped it in direction to tighten counterclockwise, then to take off clockwise.

Done close to the same with PB for stuck flywheels too. Never felled on the worst of the worst stuck yet.

the Crank is broke inside crankcase when you go to remove it it spreads out I don't want to crack crankcase

 

[glock37]

im at a lose , maybe take clutch apart and maybe able to get case separated and remove after case apart

is that possible ?

did you try the rope in the cylinder trick/method ??

Take the clutch apart, like you said but you'll probably have to destroy the spider if it's larger than the bearing.

Stuff the crankcase with rags or rope to keep the crank from turning. Then hit it with an impact or a ratchet and cheater bar

I've had to remove only one clutch from an 088 and it took a 1/2" impact. I think you would need to lock that crank together somehow, weld maybe

I tried with old cyl piston on and no go

ill have to try a few more things when I have time

thanks guys give me a few days to get back to it

I got to go easy don't want to break case

Maybe you could lock a pair of vise grips on the broken cank to hold it together, this should also keep crank from turning to make it possible to remove clutch. May want to also wrap some rags around vise grips so they don't damage case when trying to remove clutch.

thanks for all the ideas I get back to ya in a few days

thanks Mike

Double nut the flywheel side and hold it that way.

Just weld it where it is...

I would put the bearing and pin back in the rod and cut a slotted board to slip firmly underneath so the rod can't rotate. Then hit it with the impact.

I've been thinking on this a bit. With that broken crank, I think you could pressed the case halves apart even with the clutch on. The broken half of the crank will still be in the case, but at that point you should be able to grab that crank half with something and get the clutch off.
