Pump Installation |
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.
