Cush drives

[royhall]

Just getting round to removing the CB750 rear wheel bearings. Got the fine thread retainer out without too much damage but cannot get the sprocket side casting out of the old cush drive rubbers. I am starting to use too much force so thought I had better stop and ask if this is a regular problem and how to get around it. Shouldn't the cush drive plate just lift out of the rubbers or have I missed a fastener somewhere. Cheers.

You could try spraying some WD40 into the gap between the sprocket housing and the wheel hub.

They can be buggers to get out, I usually nail the wheel to the ground with my knees on the tyre and work the sprocket from side to side until it frees off and comes out.

Good luck

Panic over. I used penetrating oil and an aluminium bar through the holes and a big hammer. I only hit the rubbers though as I didn't want to crack anything. Got it in the end but crikey were those buggers stuck.

They can be real tight on them, just because the rubber bites and tries to lift out pinching the "blades" as they do.

Don't sound to worn though, as when most used the sprocket assembly falls out on it's own as you take the wheel from the frame
