Overhaul

Rocker Arm and Shaft Disassembly/Reassembly

FRONT

NOTE:
^ Identify parts as they are removed so they can be reinstalled in their original locations.
^ Inspect the rocker shafts and rocker arms.
^ If reused, the rocker arms must be installed in their original location.
^ When removing or installing the rocker arm assembly, do not remove the rocker shaft mounting bolts. The bolts will keep the springs and rocker arms on the shaft.
^ Prior to reassembling, clean all the parts in solvent, dry them, and apply new engine oil to any contact points.





REAR

NOTE:
^ Identify parts as they are removed so they can be reinstalled in their original locations.
^ Inspect the rocker shafts and rocker arms.
^ If reused, the rocker arms must be installed in their original locations.
^ When removing or installing the rocker arm assembly, do not remove the mounting bolts. The bolts will keep the rocker arms, rocker shaft bridge, and rocker shaft holder on the shaft.
^ If the rocker shaft does not remove or does not install by hand, remove or install the rocker shaft by heating the rocker shaft bridge.
^ Bundle the rocker arms with rubber bands to keep them together as a set, and remove the bands after the rocker arms have been installed.
^ Prior to reassembling, clean all the parts in solvent, dry them, and apply new engine oil to any contact points.
^ When replacing the rocker arm assembly, remove the fastening hardware from the new rocker arm assembly.
^ Never remove any of the circlips that retain the lost motion assemblies in the rocker shaft bridge. The circlips are not available separately, and are factory installed in the rocker shaft bridge. To remove the lost motion assemblies, first remove the rocker shafts and rocker arms.
