Omega CLS5500 - filter drive wheels

[darinwc]

I have an Omega CLS 5500. I was having problems getting it to 0 out the yellow filter. I noticed that it did not look like the filter was moving.

Upon opening up the head, it looks like the rubber on the wheels that drive all 3 filters have gone to mush.

Can I replace the rubber with O-rings or or something similar?

dimensions of the rubber wheels are as follows:

Shaft = 8mm
Rubber Outer Diameter = 11mm
Rubber width = 5mm

Also, these replacement wheels do happen to be one of the few parts that are still available for the enlarger.
