Clearance Inspection

Clearance Inspection
Measure both the intake rocker shaft and exhaust rocker shaft.




1. Measure the diameter of the shaft at the first rocker location.




2. Zero the gauge to the shaft diameter.




3. Measure the inside diameter of the rocker arm and check for an out-of-round condition.
4. Repeat these measurements on all the rockers.
- If the clearance is over the service limit, replace the rocker shaft and all over-tolerance rocker arms.
