Can anyone tell me of another way to pull the flywheel on a 2011 polaris rzr 900xp? I ordered a puller from Dennis Stubblefield Sales and it would not thread on. ( 50mm x 1.5 left hand thread ). It goes on 1/2 turn and stops. Tried another one and same thing. I've looked at the threads on the flywheel and they look perfect.Need to check my one way clutch gear...having starting issues. Thanks..I'm leary of forcing the puller past where it stops in case this is the wrong puller. I called Stubblefield and they siad it was correct for my model.
