Check (Condition)
1. Check the rocker shaft and rocker bushings for
signs of damage and excessive wear. Measure
the rocker shaft diameter and rocker bearing
bushes to confirm they are within service limits.
Refer to Technical Data. Note: The rocker
bearing bushes are not renewable. If a rocker
bearing bush is damaged or worn the rocker
must be renewed as a complete assembly.
Refer to: PIL 15-42.
2. Make sure that all oil-ways and cross drillings in
the rocker shaft, rocker arms and pedestals are
clear and free from debris. Use an air line to blow
through cross drillings.
