ABSTRACT:
A retainer is installed on the pedestals of adjacent rocker arm assemblies to tie the pedestals, rocker arms, and retainer into a permanent subassembly. The retainer includes rectangular apertures for receiving the pedestal shanks which in one direction comprise spring steel tabs which grip the sides of the pedestal shank with high unit loading and in the other direction provide generous clearance to permit axial sliding adjustments of the pedestals relative to each other to align the bolt holes and thus facilitate installation of the subassembly on the engine head. The spring steel tabs further align the pedestals with each other and with the engine and prevent the pedestals from turning when the tie down bolts therethrough is torqued.
