Timing Component Alignment Marks: Locations

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.

Using the crankshaft pulley bolt, turn the crankshaft clockwise to position the No. 1 piston at Top Dead Center (TDC).
The hole in the crankshaft pulley should be in the 6 o'clock position.






NOTICE: The Camshaft Alignment Plate 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 Camshaft Alignment Plate cannot be installed, rotate the crankshaft one complete revolution clockwise to correctly position the camshafts.
Install the Camshaft Alignment Plate in the slots on the rear of both camshafts.






Remove the engine plug bolt.





NOTE: The Crankshaft TDC (Top Dead Center) Timing Peg will contact the crankshaft and prevent it from turning past TDC (Top Dead Center). However, the crankshaft can still be rotated in the counterclockwise direction. The crankshaft must remain at the TDC (Top Dead Center) position during disassembly.
Install the Crankshaft TDC (Top Dead Center) Timing Peg.






NOTICE: The crankshaft must remain in the Top Dead Center (TDC) position during removal 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 removed using an air impact wrench (1/2-in drive minimum).
