Timing Component Alignment Marks: Locations

NOTICE: Do not loosen or remove the crankshaft pulley bolt without first installing the special tools as instructed in this procedure. The crankshaft pulley and the crankshaft timing sprocket are not keyed to the crankshaft. 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 the pulley bolt is loosened. Before any repair requiring loosening or removal of the crankshaft pulley bolt, the crankshaft and camshafts must be locked in place by the special service tools, otherwise severe engine damage may occur.

NOTICE: 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.

Turn the crankshaft clockwise to position the No. 1 piston at Top Dead Center (TDC).

Remove the engine plug bolt.





NOTE: The Crankshaft TDC Timing Peg will contact the crankshaft and prevent it from turning past TDC. However, the crankshaft can still be rotated in the counterclockwise direction. The crankshaft must remain at the TDC position until the timing drive components and crankshaft pulley are installed.

Install the Crankshaft TDC Timing Peg.





NOTICE: Install the camshafts with the alignment slots in the camshafts lined up so the Camshaft Alignment Plate can be installed without rotating the camshafts. Make sure the lobes on the No. 1 cylinder are in the same position as noted in the disassembly procedure. Rotating the camshafts when the timing chain is removed, or installing the camshafts 180 degrees out of position, can cause severe damage to the valves and pistons.

NOTE: Install a new crankshaft sprocket diamond washer on both sides of the crankshaft sprocket.

Install the crankshaft sprocket, new crankshaft sprocket diamond washers, oil pump chain and oil pump sprocket.

- The crankshaft sprocket flange must be facing away from the engine block.





Install the oil pump chain, sprocket and bolt.





NOTICE: The Camshaft Alignment Plate is for camshaft alignment only. Using this tool to prevent engine rotation can result in engine damage.

Install the Camshaft Alignment Plate in the slots on the rear of both camshafts.





Install the camshaft sprockets and the bolts. Do not tighten the bolts at this time.





Install the timing chain.





NOTICE: The Camshaft Alignment Plate is for camshaft alignment only. Using this tool to prevent engine rotation can result in engine damage.

Using the flats on the camshafts to prevent camshaft rotation, tighten the bolts.





NOTE: Do not install the crankshaft pulley bolt at this time.

Position the crankshaft pulley onto the crankshaft with the hole in the pulley at the 6 o'clock position.





NOTICE: Only hand-tighten the 6 mm x 18 mm bolt or damage to the front cover can occur.

NOTE: This step will correctly align the crankshaft pulley to the crankshaft.

Install a 6 mm x 18 mm bolt through the crankshaft pulley and thread it into the front cover.





NOTICE: The crankshaft must remain in the Top Dead Center (TDC) position during installation of the pulley bolt or damage to the engine can occur. Therefore, the crankshaft pulley must be held in place with the Crankshaft Damper Holding Tool and the bolt should be installed using hand tools only.

NOTE: Do not reuse the crankshaft pulley bolt.

Install a new crankshaft pulley bolt. Using the Crankshaft Damper Holding Tool to hold the crankshaft pulley in place, tighten the crankshaft pulley bolt.





Remove the 6 mm x 18 mm bolt.





Remove the Crankshaft TDC Timing Peg.





Remove the Camshaft Alignment Plate.





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

Turn the crankshaft clockwise one and three-fourths turns.

Install the Crankshaft TDC Timing Peg.





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

Turn the crankshaft clockwise until the crankshaft contacts the Crankshaft TDC Timing Peg.





NOTICE: Only hand-tighten the bolt or damage to the front cover can occur.

Using the 6 mm x 18 mm bolt, check the position of the crankshaft pulley.
- If it is not possible to install the bolt, the engine valve timing must be corrected.





Install the Camshaft Alignment Plate to check the position of the camshafts.
- If it is not possible to install the Camshaft Alignment Plate, the engine valve timing must be corrected.





Remove the Camshaft Alignment Plate.





Remove the 6 mm x 18 mm bolt.





Remove the Crankshaft TDC Timing Peg.





Install the engine plug bolt.
