Do I need to remove this collar and put it on my new rear sprocket bearing?

I am replacing all rear bearings. The new bearings do not have this collar. Is it part of the OEM bearing or should I be able to remove it?\


Thanks!

Yes, tap it out carefully with a drift punch, it shouldn't be in there very tight

Ok, that's what I thought. Mine is in there pretty tight. I tap from the other side on the little ridge?

Mine was a bitch to get out when I did my bearings a month or so ago. I ended up finding a tapered socket that fit inside of it and used that to tap it out... That was the worst part of the project by far.

This is good advice. It is important to find or make a properly sized tool to press the collar out of the bearing bore. Trying to simply tap it out with a punch or drift will likely damage the collar. Likewise, if the new bearing is not supported properly (full support on the inner race) that bearing will be ruined when you press in the collar.

Yes, both of you got it spot on. My pin punch damaged the collar. However, I somehow was able to remove it with the end of the 919's axle. Went in very nice to the new bearing.

I use one of these to remove the bearings. Pretty sure I used it to get that collar out too. Basically a slotted insert that goes inside to the inner race and a long screwdriver that drives into that slot to expand it and grab the bearing. You then elevate it and drive the bearing out.

make sure the axle slides smoothly through/in the collar after the damage. Even with using what seemed like the right tool, mine developed a small peened over edge and wouldn't allow the axle to freely move through. I ended up just throwing it on a lathe and touching the corner down, but a file likely would have worked fine as well.
