INSTALLATION
NOTE
Before pump installation the engine cylinders must be properly positioned. This is done through
coordinated positioning of two marks. One on the flywheel diameter and the other on the back
face of the camshaft gear as seen through the opening where the pump was removed. To view the
flywheel mark you must open a viewing port located on the starboard lower quarter of the flywheel
housing edge. (Below rear starboard engine mount bracket)
