See Figure 10-65 and Figure 10-66.
2. Pull the pump downwards before tightening the
screws at the specified torque. See Section 1.5.
3. The clearance on the pump screw holes allows

counterclockwise rotation (as viewed from the
engine flywheel). Also, the oil pump is located on
the crankcase's left side.
