for bearing assembly.
Determining Thickness of
Shims for Bearing Assembly
Note:
The adjustment of bearing assembly is
important for axial play of automatic
transmission.
Consequently the thickness of shims has to
be determined again after repairing or
replacing a bearing assembly.
Use a depth gauge to measure distance from
tapered roller bearing surface to tearing
flange surface (for example: 34.55 mm).
Since the design calls for a distance of only
34 + 0.05 mm, a shim 0.55 mm thick has to
be used.
