NOTE
Remover Cam Follower and Push Rod (Cylinder Head Removed)
Inspect the rocker arms for galling or wear on the pallets (valve or injector contact
surfaces). If worn, the surface may be refaced up to a maximum of .010 inch (0.025
cm). However, proceed with caution when surface grinding to avoid overheating the
rocker arm. Maintain the radius and finish as close to the original surface as possible.
Also inspect the valve bridges for wear.
