Step: 2
Locate top dead center (TDC) of the compression stroke on
cylinder No. 1. The following procedure uses the engine
timing pin, but other alternate methods, such as the dropped
valve method, can be used.
Step: 3
CAUTION
Do not bend the fuel lines. Bending the lines will cause
line or injector failure.
If the injection lines have not already been removed, re-
move the No. 1 injection line.
Step: 4
WARNING
Wear appropriate eye and face protection when using
compressed air. Flying debris and dirt can cause bodily
injury.
CAUTION
Do not loosen the two barrel flange nuts located below
the delivery valve holder. Loosening of these nuts will
void the fuel injection pump warranty.
NOTE: There is an external o-ring on the holder to help
prevent debris from getting into the pump; this can create
a slight resistance as the holder is loosened.
With the engine at TDC, loosen, but do not remove the front
(No. 1) delivery valve holder using the special socket pro-
vided in the timing kit. Use compressed air to remove any
paint chips from around the delivery valve holder. Remove
the special socket prior to removing the delivery valve
holder from the fuel injection pump.
