1-6 CAMSHAFT AND FUEL CAMSHAFT
IAl Camsh
The camshaft is made of special cast iron and the journal and
cam sections are chilled to resist wear. The journal sections
are force-lubricated. The fuel camshaft controls the recipro ­
cating movement of the injection pump, and is equipped
with a ball to control the governor. Fuel camshaft is made of
carbon steel and cam sections are quenched and tempered to
provide greater wear resistance.
