1) Camshaft End play
•
Push the thrust plate toward the cam
gear.

With a feeler gauge, measure the clear-
ance between the thrust plate and
camshaft journal.
•
If the end play is excessive, replace the
thrust plate.
2) Cam
•
Cam lobe height
Use a micrometer to measure the cam
lobe height and journal diameter.
If the measured number is less than the
specified
limit,
the
camshaft
must
replaced.

Cam surface
Inspect the cam face for scratch or damage.
Slight step wear or damage on the cam face may be corrected with oil stone or oiled grind-

•
Clearance
between camshaft journal and camshaft bush
- With an outside micrometer, measure the camshaft journal diameter.
