CAMSHAFT(S)
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.
