Okay, so I've removed the axles from my AMC 20, and am about to put it all back together - these are two piece axles, and my brake backing plate will not allow the inner bearing to pass though. As I understand it, the order of the parts is the following:
Inner seal > Axle with bearing pressed on, tapered side out > Race (or bearing cup) > SHIM(s) > Brake Backing Plate > OUTER seal (aka: axle retainer plate) > Outer seal retainer > Hub (with key in place).
Correct me if the above is wrong.
The SHIMS are to go between the housing flange and the Brake Backing Plate correct?
Also, I can't find any specifics on the SHIM use .. when I disassembled my AMC 20, there was 1 SHIM on one side, and 3 SHIMS on the other.
I've read where they are used to "pre-load" the bearings, which I assume means reduce / remove slack, but can't find any details on the calculations or testing to confirm .. I've seen details on one-piece axles though.
