Hoping someone can help. I need the bearing dimensions for the RC500 Rear bulkhead (large size)? I believe the Associated part number is 5256.

Thanks, Limestang

1 11/64" X 21/32"

Looks like an odd size. Has anyone had luck with a source for this bearing?

Thanks Limestang

Looks like they could be 30mm x 17mm metric instead of what I originally thought.

Turns out this is an odd size bearing and difficult to find. I decided to machine a pair of aluminum spacers to allow use of the easier to source bearings. I will post a photo tomorrow in case someone else encounters a similar problem.

Here is the photo. The white bulkhead uses the machined aluminum spacer. I sized for a light press fit.

The large bearings in my RC500's are all 12mm x 24mm.

Thanks 8valve.
