There. is a selection of shims serviced by the.
manufacturers in thicknesses from 2.9 to 4.5 mm in
increments of .1 mm. There are also shims of the thickness
of 0.25 mm serviced providing for adjustments in
increments of 0.05 mm.
The determined shim thickness is to be increased or
reduced to the next thickness which is similar to the shims
serviced, but the total shim thickness of Sl and S2 must
remain within the permissible tolerance to ensure that the
two differential ball bearings are correctly pre-loaded.
With determined shim thickness as calculated, viz; Sl =
3.77 mm; S2 = 3.72 mm; Sl
+
S2 = 7.49 mm; use
approximately shim thickness as follows: Sl = 3.80 mm; S2

S2 = 7.50 mm.
Check the thickness of the shims with a micrometer,
measuring at four different points. The permissible
variation is 0.03 mm.
