Timing Component Alignment Marks: Locations

CAUTION: Since the engine is not free-wheeling, the timing procedures must be followed exactly or piston and valve damage can occur.

CAUTION: Unless otherwise instructed, at no time when the timing chains are removed and the cylinder heads are installed is the crankshaft or camshaft to be rotated. Severe piston and valve damage will occur.

CAUTION: Timing chain procedures must be followed exactly or damage to valves and pistons will result.

CAUTION: Rotate the crankshaft counterclockwise only. Do not rotate past position shown or severe piston and valve damage can occur.




If the copper links are not visible, mark two links on one end and one link on the other end, and use as timing marks.




1. LH camshaft timing mark is approximately at 12 o'clock.
2. RH camshaft timing mark is approximately at 11 o'clock.




Install the crankshaft sprocket, make sure the flange faces forward.




Position the lower end of the LH (inner) timing chain on the crankshaft sprocket, aligning the timing mark on the outer flange of the crankshaft sprocket with the single copper (marked) link on the chain.




Position the timing chain on the camshaft sprocket with the camshaft sprocket timing mark positioned between the two copper (marked) chain links.




Position the lower end of the RH (outer) timing chain on the crankshaft sprocket, aligning the timing mark on the sprocket with the single copper (marked) link on the timing chain.




Position the RH timing chain on the camshaft sprocket. Make sure the camshaft sprocket timing mark is positioned between the two copper (marked) chain links.




Verify correct alignment of all timing marks.
