75. Press the small ball bearing onto the slipping
clutch. Use tool no. 884733.
76. Preferably use the shims which were installed pre-
884729
viously, if only new bearings have been installed. In
other cases, the shim thickness can be calculated as
in items 77–84.
Calculate the shim thickness for the small bearing
race in the slipping clutch. The housing is stamped
with a D dimension and an E dimension.
Let us assume that the D dimension = 88.82 mm and
the E dimension = 61.30 mm.
NOTE! The D dimension is based on 88.00 and only
the decimals are stamped. The E dimension is based
on 61.00, to which the stamped value should be add-
ed.
Thus: 88 + 0.82 = 88.82 and 61.00 + 0.30 = 61.30.
The example below shows how the shim thickness is
calculated.
Example:
D = 88.82 NOTE! only 82 is stamped
E = 61.30 NOTE! only 30 is stamped
D–E = 27.52
