NOTE: : The crankshaft gear contains a single timing mark. The camshaft drive gear contains a single timing mark and a double timing mark. The fuel injection pump drive gear contains a double timing mark. The engine is timed correctly when the single mark on the crankshaft drive gear is aligned with the double mark on the camshaft drive gear, and the single mark on the camshaft drive gear is aligned with the double mark on the fuel injection pump drive gear. Additionally, the keyway on the fuel injection pump drive gear must be in the 12 o'clock position.
Rotate the crankshaft clockwise, as viewed from the front, until the single mark on the camshaft drive gear and the double mark on the fuel injection pump drive gear are aligned.
