Abstract: A rocker arm assembly including a rocker body having an upper wall arranged above a pivot axis, two ears extending from opposing sides of the upper wall and defining a pivot bore coaxial with the pivot axis, and a pad end wall and a socket end wall each extending from the upper wall and the ears. A pad having a convex pad surface is formed on the pad end wall for engaging a valve and a socket having a concave socket surface is formed on the socket end wall for engaging a pushrod. The rocker arm assembly further includes a trunnion body and a bearing, each disposed in the pivot bores and for facilitating pivoting movement between the rocker body and the trunnion body.

Abstract: A tappet assembly for use in translating force between a camshaft lobe and a fuel pump assembly via reciprocal movement within a tappet cylinder having a guide slot. The tappet assembly comprises a tappet body defining a pair of apertures and at least one seat, and a follower assembly. The follower assembly has a shaft, a first bearing, and a second bearing, each supported on the shaft for engaging the camshaft lobe. An intermediate element is further supported on the shaft between the first and second bearings and has a platform for engaging the fuel pump assembly. The intermediate element is at least partially disposed in the at least one seat of the tappet body and the shaft is disposed in the pair of apertures of the tappet body.
