The camshaft is made of special cast iron; the journal
and cam sections are chromed to resist wear. The journal
sections are force-lubricated. The fuel camshaft controls
the reciprocating movement of the injection pump, and
is also equipped with a ball to control the governor. Fuel
camshaft is made of carbon steel and cam sections are
covered and tempered to provide greater wear resistance.
The rocker arm assembly includes the rocker arms, arm
brackets and arm shafts and converts the movement
of the push rods to open/close of the inlet and exhaust
valves. Valve controlled timing must be adjusted with
screws on the rocker arms. Lubrication oil is pressurized
through arm bearings and the entire system is lubricated.
