CAMSHAFT(S)
DESCRIPTION
Both camshafts have six bearing journal surfaces
and two cam lobes per cylinder (Fig. 17). Flanges at
the rear journals control camshaft end play. Provision
for a cam position sensor is located on the intake
camshaft on the rear of the cylinder head. A hydro-
dynamic oil seal is used for oil control at the front of
the camshaft.
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.
