CB360 Sprocket Bushings in Rear Hub and Bearing Removal

[Jordan918]

I need to remove four rubber/metal bushings from my rear hub. They hold the sprocket bolts and they are dang near impossible to get out. I've gotten two out, somehow...someway, but I'd like to know what the best method is before I proceed to the final two.

Also, any tips on bearing removal would be appreciated. Already tried the 'concrete tap anchor' method and it keeps sliding out.

Can't see the pic so I can't help you on the rubber things.

Bearing removal can be done by drifting them out from the other side (put a drift through the axle hole, pull it sideways to move the bearing spacer and tap away on the inside race).

Make sure you've removed any retaining rings / circlips if your hubs have them.

It's not normally possible to get the drive pin bushings out without destroying them
You have unscrewed the bearing retainer on rear hub?
You can push the internal spacer slightly sideways and use a drift, fill brake drum with boiling water to expand the alloy, makes life a lot easier
You will probably need new bearings

I always heat the hub around the bearing with a torch. It makes the hub expand, and the bearing come out MUCH more easily. Heating the hub makes it often possible to remove bearings without ruining them. I made what I call a "mushroom punch." It's a piece of 3/8" steel rod with a concave flair on the end that is flame-hardened. It's good to get in that little chamfer on the bearing race to get it started coming out.

Harbor freight has a blind hole bearing puller for cheap. Works awesome.

Not sure why you cant see the pic. Its up on my screen. I just had to scroll to the right.

The rubber portion and the inner metal of the drive pin bushings are the "easy" part. The outer metal casing is the part that is giving me fits. Nothing to grab on to.


Ive decided that a legit bearing puller may be my first tool investment. Sounds like they are good to have around.


Really appreciate the advice.
