Timing Component Alignment Marks: Locations
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.
