Front Sprocket question

[cmraracer]

Ok I'm still confused. Does the large splined shaft that the compensator slides on come off? Manual doesn't have pics or anything and the rotor will not slide out over the shaft.

This shaft is killing me!! Guess its galled on or something. Guess I'm gonna have to destroy it to get it off?

Does everythig turn freely? Rotar and stator are not binding or something. Do you hear anything when you rotate the engine?

 

[cmraracer]

no everything was rotating ok. There is a hollow shaft that the compensator bolt goes inside of that is overnight the top of the motor output shaft or crank output shaft. This hollow shaft is what the sprocket rides on and is holding the rotor in place. I've talked to Big Dog and theg act like it should just fall off in my hand. I've basically drilled the rotor trying to get a puller behind it and still won't budge. I guess I'm gonna drill the shaft now and put a bolt in it so I can get a puller on it or a slide hammer. The shaft and rotor will be destroyed and I'm sure they're real cheap! Im thinking open primary now! Sucks!

Don't drill out your crank shaft !

Linten to V. Drill the splined crankshaft and you're looking at a bottom end job. Spray the splined portion with some PB break and let it soak. The stator should just come off easy, but there is a big magnet behind it. The crank and splines are hardened, much harder than the stuff spinning with it, so it's not likely there is any damage to the crank. Slip some picks or allen wrenches in the holes on the stator and make sure you pull evenly. Kepp fooling with it, it will come off.

Worst case remove the clutch hub and entire primary/motor plate assembly. Then you'll have easy access to it.

Trust me it's not the crank shaft! I would never do that. This shaft appears to slide on over the crankshaft.

You need to post a picture. I don't remember what's inside a stock primary. Look at the picture in my last post, that's your motor. Ignore the big nut hanging off there, it's for an open primary. The splined shaft you see the nut attached to is your crankshaft. The black bowl is the stator rotor. It's just a black bowl. Behind that is the stator magnet that is bolted to the motor case. The bowl spins with the crank around the stationary magnet.

I believe the hollow shaft is the one in this Picture, that the front sprocket rides on. I swiped this off CMRARACER'S face book page.

any one got any ideas on Cmraracer's Issue? I'm going to go over next week to help out. thinking of pulling the primary cover off to see if we can get a better angle on how to get it off. Maybe heating up the hollow shaft might help. At this point I'll willing to give any thing a try.
