).
MEASURING M

d. Measure the distance ring (M
7
) and adjustment
shims thickness (M
8
).
Add these measure-
ments to obtain dimension B.
e. From dimension A, subtract dimension B.
The result is the actual crankshaft end-play that
must be within specification.
If the result is over specification, add adjustment
shim(s) to reach this specification.
If the result is under specification, remove adjust-
ment shim(s) to reach this specification.
