Oil Clearance between Rocker Arm Shaft and Bearing
1. Measure the rocker arm bearing I.D. with an inside micrometer.
2. Measure the rocker arm shaft O.D. with an outside micrometer,
and then calculate the oil clearance.
3. If the clearance exceeds the allowable limit, replace the rocker
arm and measure the oil clearance again. If it still exceeds the
allowable limit, replace also the rocker arm shaft.
