Crankshaft Pulley - Removal
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.
1. Remove and/or disconnect components to allow
access and removal of the crankshaft pulley. Label if
necessary to allow for correct reinstallation.
2. Remove the drive belt -- refer to Section 6.
3. Remove the camshaft cover -- Refer to“Camshaft
Cover - Removal” on page 6 of this section.
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.
4. Using the crankshaft pulley bolt, turn the crankshaft
clockwise to position the No. 1 piston at TDC.
CAUTION: The special tool 303-465 is for camshaft
alignment only. Using this tool to prevent engine
rotation can result in engine damage.
5. Install special tool 303-465 in the slots on the rear of
both camshafts.
NOTE: Camshaft timing slots are offset. If special tool
cannot be installed, rotate crankshaft one complete
revolution clockwise to correctly position camshafts.
6. Remove plug bolt.
CAUTION: Installing special tool in this next step
will prevent engine from being rotated in the
clockwise direction. However, the engine can still
be rotated in the counterclockwise direction. Only
turn the engine in the normal direction of rotation.
7. Install special tool 303-507.
8. Install special tools 205-126 and 205-072-02
CAUTION: Failure to hold the crankshaft pulley in
place during bolt loosening can cause damage to
the engine.
