Shim
adjustment
for
output
and
input
shafts
Check
the thickness of the shims for the intermediate,
clutch,
input and
output
shafts. When the component
parts are not replaced after dismantling, the same shims
can
be reused. When the clutch
case,
mounting flange and
clutch
case
cover or any one of the following parts is re-
placed
the shim thickness must be determined in the
following manner.
For
input shaft parts :
For
output
shaft parts:
For
intermediate
shaft parts
For
clutch shaft parts :
input shaft, bearing,
output
shaft, bearing.
intermediate shaft, spacer, gear
bearing.

NOTE: When measuring the distances I and J, the clutch
gears must be pushed in the direction of the drive
cone.
