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
BELT/CHAIN
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.

OPERATION

The camshaft is driven by the crankshaft via drive
sprockets and belt. The camshaft has precisely
machined lobes to provide accurate valve timing and
duration.
STANDARD PROCEDURE - MEASURING
CAMSHAFT END PLAY
(1) Oil camshaft journals and install camshaft
WITHOUT rocker arms. Install rear cam caps and
tighten screws to specified torque.
(2) Using a suitable tool, move camshaft as far
rearward as it will go.
(3) Zero dial indicator (Fig. 19).
(4) Move camshaft as far forward as it will go.
(5) Record reading on dial indicator. For end play
