Timing Component Alignment Marks: Locations

TIMING CHAIN






NOTE: The crankshaft timing mark (3) or (5) can be in one of two locations depending on whether the engine is early production (5), late production (3) or assembled with service parts (3). In all cases the keyway (2) will always be in the 9:00 position, in line with the ladder frame mounting surface (1) when the engine is at TDC.

1. Verify that the engine is still set to TDC.




2. Align camshaft timing marks (3) so they are facing each other and in line with the cylinder head cover sealing surface (2).
3. Install timing chain so plated (or marked) links on chain align with timing marks on camshaft sprockets (1).





4. Align timing mark on the crankshaft sprocket (3) or (5) with the plated (or marked) link (4) on the timing chain. Position chain so slack will be on the tensioner side.
