Title: Honda CR250 Rear Wheel Bearings
Post by: HL500 on April 13, 2015, 03:07:29 pm

Is there a special technique to remove the left side large wheel bearing?  I've tried the normal driving and press techniques including warming up the hub but the bearing isn't budging.

Before I put more pressure into it I'd like to be sure there's not a retainer or something in the way.

I've consulted the manual but there is nothing indicated.  I noticed that there is a steel sleeve on the outside of the aluminum housing where the bearing presses in. Is this correct?

I can vouch for the '84 rear hubs.

The bearing is pressed in per normal bike practice.

The threaded retainer is fitted on the drum side.

If you are talking 78-80,non brake/sprocket side I'm guessing you have removed the alloy threaded insert that the seal sits in?

 If so the bearing should just tap out as normal :)

Thanks guys for your comments.  The bearing I was referring too was the brake side so not involving the retainer ring.

Anyway I ended up getting brutal with it as it was plainly obvious that it had to come out.  Got a mate to hold the driving bar and belted it out.  I think the problem was that the innards were rusted and that effected the bearing surface.

Yep, bigger hammer often works too
