It
is recommended to bar the engine over so that the keyway on
the gear is at the 12-o'clock position when installing the fuel
pump. This position can be found by taking the oil fill or fuel
pump gear access cap off, whichever applies, and aligning the
keyway in the fuel pump gear to the top dead center (TDC) position
on the front cover. In this position the line on the fuel pump
gear will approximately be in the 7-o'clock position.
NOTE: Doing the above will help prevent the fuel pump
key from falling into the gear housing if it is loose.
The keyed
gear and shaft allow for the fuel injection pump to be installed
in any position, as long as the markings on the front gear train
align and a gear has not slipped.
Use an evaporative cleanser (e.g., brake cleaner,
isopropyl alcohol) to clean the pump shaft and gear bore.
NOTE:
The fuel injection pump shaft has to be rotated to align with
the keyway in the gear.
Install the pump. Make sure the key does not fall into the gear
housing. Take care not to damage the pump mounting o-ring.
NOTE: When installing the fuel pump,
the dowel in the back of the gear housing has to line up with
the hole in the pump mounting flange, as well as the keyway
in the gear.
NOTE: Barring the engine so the keyway is at the 12-o'clock
position will aid in aligning the key into the keyway.
