Oil Clearance between Valve Bridge Arm and Valve Bridge
Shaft
1. Measure the valve bridge arm (1) I.D. with an inside micrometer.
2. Measure the valve bridge shaft (2) O.D. with an outside
micrometer, and then calculate the oil clearance.
3. If the clearance exceeds the allowable limit, replace the valve
bridge arm (1) and measure the oil clearance again. If it still
exceeds the allowable limit, replace also the valve bridge shaft
(2).
