of gear segment.
6. Push down on extractor (5) (hand force only) and
install O-ring and bushing that holds the injec-
tion pump in the pump housing. If the pump is
in the correct position, the bushing will turn into
the threads of the fuel injection housing with the
fingers until it is even with the top of the hous-
ing. When the bushing is installed correctly,
tighten the bushing to 160 ± 14 N·m (120 ± 10
lb. ft.).
CAUTION
The bushing must be tightened to the correct
torque. Damage to the housing will be the re-
sult if the bushing is too tight. If the bushing is
not tight enough, the pump will have leakage.
