Crankshaft Pulley: Removal

CAUTION: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan can cause engine failure.

CAUTION: The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction, using 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 re-timed each time the damper is removed. Otherwise severe engine damage can occur.

Remove the accessory drive belt. For additional information, refer to ACCESSORY DRIVE .
Remove the valve cover. For additional information, refer to VALVE COVER .

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.

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.

NOTE: The camshaft timing slots are offset. If the special tool cannot be installed, rotate the crankshaft one complete revolution clockwise to correctly position the camshafts.

NOTE: Only turn the engine in the normal direction of rotation.

NOTE: Installing the special tool in this step will prevent the engine from being rotated in the clockwise direction. However, the engine can still be rotated in the counterclockwise direction.
