Issue with bearing retainer of Wilwood 140-11403 brake kit with drum e-brake
#1
I am installing the Wilwood 140-11403 disc brake kit for the rear. This one has a drum e-brake that doubles as a backing plate. The drum brake backing plate goes flush against the axle flange and then there is a bearing retainer that has an inside folded lip that should retain the bearing. The problem is that this folded lip is about 0.025" short of contacting the bearing. I have new axles/bearings from Strange. Called Wilwood and they say that it should work, but it doesn't. Strange says that this are standard bearings. I found one thread online where the person was having a similar issue. As a background, I did make sure the backing plate and flange are clean and flushed. I did measurements before the installation because I was suspicious of the problem and then confirmed the problem after installation.

In any case, i need to move forward and find a solution. The easiest would be to find a shim or washer that I could fit in that opening. It would have to have a diameter larger than 2.64" ID and less than 2.95" OD. The thickness is not that critical because if it is thicker I could shim the bearing retainer plate. Needless to say I can't find anything for that application. I am hoping someone has an idea of a shim/washer for another application that has similar dimensions that I can make work. Even if the OD is larger I could grind it down. It doesn't need to have a perfect OD as long as the thickness is constant. Heck, I even looked at a 67mm camera filter adapter that I may be able to make work. Looking for ideas. Thanks.

Here is the diagram from Wilwood:

On my car I had to get rid of some powder coating. Before I did that I was using air cooled 1600CC VW flywheel shims. Worked pretty good for a small bearing Ford 9"

Interesting. Do you know the ID and OD of these shims?

I do not know, but I could measure one Friday

I found some in ebay and the seller said 53-70mm. That would be too small of a bore. I need 67-75mm. However, if you can, please measure them in case there are other sizes.

An idea would be to use piston rings, but they would need to be 67ish mm when fully open. There has to be something out there that I could use as a shim.

Bump again. Ideas any one? I need a shim that is approximately 67mm ID x 75mm OD x 0.6mm (2.64x2.95x0.025"), or something that I can make work as a shim? The closest I found was a shim for a Kobelco excavator that is 67x100x0.5 mm. I would be able to make it work if I can cut the OD.

Maybe buy some shim stock and cut out your own.

Something else you can look for are arbor shims. I found these that are close to the size you need.

Great find Don. I even looked at their website but I guess I missed these ones. I would have to reduce the OD but that shouldn't be that difficult specially that it doesn't need to be perfect round on the OD.
