Engine Maintenance (Rev 6/98)
66
a.
Turn the crankshaft clockwise from the front, until
the TC mark on the flywheel aligns with the
pointer on the flywheel housing.
Top Dead Center Marks
b.
Wiggle the push rods on the No. 1 intake and
exhaust valves. If both push rods are loose enough
to turn freely, the No. 1 piston is at TDC on the
compression stroke. This is the first adjusting posi-
tion.
If instead, the No. 1 push rods are tight and the No.
4 push rods are loose, the No. 4 piston is at TDC in
the compression stroke. Turn the crankshaft clock-
wise from the front, until the TC mark on the fly-
wheel is aligned. Now both No. 1 push rods should
be loose, and the No. 1 piston is at TDC of the
compression stroke.
An alternate method is to remove the camshaft
gear access cover and rotate the engine until the
“O” on the cam gear lines up with the pointer and
the TC mark on the flywheel lines up with the
pointer on the bellhousing.
Adjust both valves on the No. 1 cylinder, the intake
valve on the No. 2 cylinder, and the exhaust valve
on the No. 3 cylinder.
c.
Turn the crankshaft one full turn, clockwise from
the front, and align the TC mark. This is TDC of
the No. 4 cylinder compression stroke. Adjust the
No. 2 exhaust valve, the No. 3 intake valve, and
the No. 4 intake and exhaust valves.
d.
Make sure to tighten each lock nut while holding
the adjusting screw in position.
e.
Install the rocker arm cover making sure that the
gasket is in position.
FRONT PULLEY BOLT
The front crankshaft pulley bolt should be torqued during
scheduled maintenance inspections. The bolt should be
torqued to 218 N•m (161 ft-lb).
NOTE: The crankshaft bolt requires a special hard steel
washer. Substituting or eliminating this washer could lead
to premature crankshaft bolt failure due to the bolt bot-
toming out or inadequate bolt head load distribution.
