z Visual check
Visually check the face of the
rocker arm in contact with the valve
stem end for scores and step wear.
If the wear is small, correct it with
an oil stone or grinding paper of
fine grain size. Rocker arm with a
considerable amount of step wear
should be replaced.
z Rocker arm bushing diameter
Measure the inside diameter of the
rocker arm bushing with an inside
micrometer or vernier calipers, and
compare the measured values with
the rocker arm shaft diameter. If the
clearance exceeds the limit, replace
either bushing or shaft, whichever
worn more.
Standard Limit
0.020 ∼ 0.093 mm
