Oil Pump-to-Engine Block Bolts

Important: Inspect the oil pump and engine block oil gallery passages. These surfaces must be clear and free of debris or restrictions.

Align the splined surfaces of the crankshaft sprocket and the oil pump drive gear and install the oil pump (413).

Install the oil pump onto the crankshaft sprocket until the pump housing contacts the face of the engine block.

Install the oil pump bolts (411).

Tighten the oil pump bolts to 25 N.m (18 lb ft).
