Oil Clearance between Rocker Arm and Rocker Arm Shaft
1. Measure the rocker arm I.D. with an internal micrometer.
2. Measure the rocker arm shaft O.D. with an external micrometer.
3. Calculate the oil clearance.
4. If the oil clearance is more than the allowable limit, replace the
rocker arm and measure the oil clearance again. If the oil
clearance stays more than the allowable limit, replace the
rocker arm shaft also.

Oil Clearance between Valve Bridge Arm Shaft and Valve
Bridge Arm
1. Measure the valve bridge arm (1) I.D. with an internal
micrometer.
2. Measure the valve bridge shaft (2) O.D with an external
micrometer.
3. Calculate the oil clearance.
4. If the oil clearance is more than allowable limit, replace the valve
bridge arm (1) and measure the oil clearance again. If the oil
clearance stays more than the allowable limit, replace the valve
bridge shaft (2) also.
