If reused, the rocker arms must be installed in their original location.
When removing, or installing the rocker arm assembly, do not remove the camshaft holder bolts. The bolts will keep the holders and the rocker arms on the shaft.
Prior to reassembling, clean all the parts in solvent, dry them, and apply lubricant to any contact points.
Bundle the intake rocker arms with rubber bands to keep them together as a set.
When replacing the intake rocker arm assembly, remove the fastening hardware from the new intake rocker arm assembly.
