2-3.2.3. Camshaft
The camshaft forging is machined on three main journals, six cam lobes and the gear
mount flange at the rear of the camshaft. The lobes and journals are ground and hardened.
Camshaft main journals are supported in the crankcase by machined bearing saddles.
Hydraulic tappets move inward and outward in their bores, following the eccentric shape
of the cam lobes. Four unequally spaced bolts secure the gear to the camshaft and ensure
proper positioning, locating the gear’s timing mark in relation to the cam lobes. The
camshaft gear has internal teeth to drive the alternator. A front-mounted bevel gear drives
the accessory drive bevel gear. The camshaft is hollow to reduce total engine weight.
