Camshaft Measurement
1. With the camshaft in a suitable fixture, measure the
camshaft for wear.
2. Measure the camshaft journals for diameter and out-
of-round using an outside micrometer. Refer to
"Engine Mechanical Specifications".
– If the diameter is smaller than specifications,
replace the camshaft.
– If the out-of-round exceeds specifications, replace
the camshaft.
3. Measure the camshaft runout using the J 7872.
Refer to "Engine Mechanical Specifications".
4. Measure the camshaft thrust width for wear using a
depth micrometer. Refer to "Engine Mechanical
Specifications".
