CYLINDER ASSEMBLY DETAILED DESCRIPTION (continued).

Valve Rocker arms, Shafts, Pushrods And Housings (Valve Train)

- Valve rocker arms

are steel forgings with hardened pushrod sockets and rocker faces. The rocker arm has a
precision bronze bushing that accommodates the rocker shaft. The rocker arm shaft is
secured to the rocker boss studs using retainers, lock tabs and nuts. They have a drilled oil
passage for lubrication. Pushrods are steel tubes with forged steel ball ends, which are
center drilled for oil passages. The pushrod housings are beaded steel tubes. The bead at
the cylinder end retains an o-ring. The bead at the crankcase end retains a heavy spring,
washer, packing ring and second washer.
