So yesturday the bearing popped on my jackshaft, the secondary side.
Last night I got the secondary off, the mount that bolts to the frame that holds the bearing and i got the old outer race from this with force (hammer and screw driver) an I got the new bearings in.
Now I cant get the old inner bearing race off the jackshaft which is still hooked up to my chain case. I just tried a heavy duty puller with as much pressure as I could apply to it with my rachet and it didn't budge! I would heat it but it is right beside my gas line.
Any other ideas?
Heres a pic of the assembly from yamaha...

Its the inner race of #13 that wont budge from the shaft
1982 Excel V if it matters

there is 1 and yes
Daman's got ya covered...or even a cut-off dremil tool, slice a line in it to take the pressure off it...it should split like daman said...good luck...cheers
You may have heated the jackshaft up and bent it if the bearing got really hot. I have a couple of those in my garage (I never throw old parts out).
Not saying that you for sure did, just suggesting that you check it closely. If it is bent it will vibrate at higher speeds.

That bearing has a locking collar on it. It locks the race to the shaft and has to be removed to remove the race. There are two seperate pieces there.
Rotate the shaft and in the ring where the set screw was, there is a hole. Put a punch in the hole and hit it with a hammer to rotate it in the opposite direction of the rotation of the shaft. If it does not move, tap it in the other direction. When it has turned about a half inch or more, it should be free. If it is not, insert a chisel between the collar and race and tap it to split it away from the race. If things are rusted up you may have to give the shaft a half turn and repeat with the chisel.
There are eccentrics in the race and lock ring. When the bearing carrier has been reinstalled and tightened, slide the lock collar against the bearing, turning it so it seats. With the punch, tighten the collar in the direction of rotation of the shaft. Moderately hit it until it stops turning, do not hit it hard. Tighten the set screw.

I had the collar off, I knew that was there. My problem was from the bearing being totally gone and the shaft spinning in the hole freely with no bearings caused the shaft to get bumpy and deformed, so after I cut off the race i sanded it down to normal and ow all is well
