Engine Assembly
CAUTION: The crankshaft, the crankshaft sprocket
and the pulley are fitted together by friction, with
diamond washers between the flange faces on each
part. For that reason, the crankshaft sprocket is
also unfastened if you loosen the pulley. Therefore,
the engine must be retimed each time the damper is
removed. Otherwise severe damage can occur.
CAUTION: Failure to position the No. 1 piston at top
dead center (TDC) can result in damage to the
engine. Turn the engine in the normal direction of
rotation only.
1. Using the crankshaft pulley bolt, turn the crankshaft
clockwise to position the No. 1 piston on TDC>
2. Remove plug bolt.
CAUTION: Only turn the engine in the normal
direction of rotation. Installing the special tool in
this next step will prevent the engine from being
rotated in the clockwise direction. However, the
engine can still be rotated in the counterclockwise
direction.
3. Install special tool 303-507.
4. Position the oil pump assembly and tighten the bolts
in the sequence shown in 2 stages:
• Stage 1: Tighten to 10 Nm (89 lb-in)
• Stage 2: Tighten to 20 Nm (15 lb-ft).
5. Position a new oil pump pickup tube gasket and the
pickup tube, and tighten 4 bolts in the sequence
