CAMSHAFT
DESCRIPTION
A single overhead camshaft per cylinder head pro-
vides valve actuation. The left camshaft accommo-
dates a cam sensor pick-up wheel and is therefore
longer. Each camshaft is supported by four bearing
journals. Thrust for each camshaft is taken at a
thrust plate attached to the rear of each cylinder
head. Right and left camshaft driving sprockets are
not interchangeable because of the cam sensor
pick-up wheel on the left sprocket. Camshaft bearing
lubrication is provided via oil feed passage through
each rocker shaft pedestal dowel.

ROCKER ARM SHAFTS
DESCRIPTION
The rocker arm shafts (Fig. 6) are tubular steel
and are supported by several forged aluminum alloy
pedestals, which are fastened to the cylinder head.
Four shafts are used, one for each intake and
exhaust rocker arm bank on each cylinder head. The
shafts are hollow to provide a duct for lubricating oil
flow from the cylinder head to the valve mechanisms.
One hollow dowel per pedestal is used to locate the
pedestal to the cylinder head, orient the exhaust
rocker shaft, and serve as a cam bearing oil feed pas-
sage.
