Rocker Arm-to-Rocker Arm Shaft Clearance
Using a micrometer and a bore gauge, measure rocker shaft dia.
and rocker arm l.D.
Difference between two readings is arm-to-shaft clearance on
which a limit is specified.
If limit is exceeded, replace shaft or arm, or both.

(0.0035 in.)
Cam Wear
Using a micrometer, measured height of cam. If measured height
is below limit, replace camshaft.

Camshaft Runout
Hold camshaft between two “V” blocks, and measure runout by us-
ing a dial gauge.
If runout exceeds the limit, replace camshaft.
Runout limit: 0.10 mm (0.0039 in.)
Camshaft Journal Wear
Check camshaft journals and camshaft housings for pitting,
scratches, wear or damage.
If any malcondition is found, replace camshaft or cylinder head with
