Rear Wheel Cush Drive Rubbers

[jimbo]

The last ones I bought were very hard, and very hard to install the wheel. Are there any out there more compliant?

jimbo,
If you have a belt sander you can take a bit off the flat of the big Rubber Cush to help in installing the rear wheel to the paddles of the brake drum. That is what I do as I had the same problem. If you don't have a belt sander then some sandpaper on a flat surface will do with some elbow grease.

You want hard rubber in the cush drive hub .
Use red rubber grease to rubber mallet them into place .
Also to the paddles , for the final tight fit .
Enjoy .

Yes there are soft rubbers and hard rubbers from suppliers my first ever replacement rubbers were soft and didn't last very long, got replacements from RGM and ordered 3 spare sets, so far they have lasted the time and I still have 2 spare set of rubbers still in my spare parts cabinet, my original rubbers lasted 35 years, the first replacements only lasted 6 months, the second replacement have lasted 12+ years so far, I used rubber grease to fit them.

Completely agree. BTW, do not use wheel bearing grease - red rubber grease only.

I've used them from AN and Wassell. Can't tell any difference, both are a tight fit and I think that's good.

Greg,
Why is wheel bearing grease a bad idea?
Thanks,Mike

The ones I got from norvil were good. Not hard as glass. Wheel mounted easily. Would recommend.

They are likely nylon which absorbs grease and expands, nylon does not absorb silicone based greases. I have nylon tracks on my door opener and only use silicone based grease for that reason.

Are the Norvil ones available here in the states?

Some greases attack rubber and there are many kinds of wheel bearing grease so I used the term generically. The Red Rubber grease is formulated for rubber and does not attack/soften rubber. Here is the one AN sells and I use for isoelastic and cush rubbers: https://andover-norton.co.uk/en/shop-details-2/18449

Its funny how the original ones just crumble away into dust in a wheel that has not been installed in 40yrs.
