Keep all parts clean from contaminants. Contaminants put into the system may cause rapid wear and shortened component life.
1. Turn the crankshaft until the "C" mark on the crankshaft gear is in alignment with the "C" mark on the camshaft gear. To keep the engine timing correct during removal and installation of the camshaft, put a mark on the teeth of the fuel injection pump drive gear and idler gear at location (A).
