Oil Clearance between Rocker Arm Shaft and Shaft Hole
1. Measure the rocker arm shaft O.D. with an outside
micrometer.
2. Measure the rocker arm shaft hole I.D. with an inside
micrometer, and calculate the oil clearance.
3. If the clearance still exceeds the allowable limit, replace the
rocker arm.
4. If the clearance still exceeds the allowable limit after replacing
the new rocker arm, replace the rocker arm shaft.

1. Measure the I.D. of cylinder liner with a cylinder gauge at 6
points as shown in the figure to obtain the maximum wear.
2. If the measurement exceeds the allowable limit, the cylinder
liner needs to be bored to an oversize, and then hone-finished.
3. When the oversize allowable limit is exceeded, replace the
