This will ensure proper gear-to-shaft tighten-
ing.
(5) Clean pump gear and pump shaft at machined
tapers with an evaporative type cleaner such as
brake cleaner.
(6) Position injection pump to mounting flange on
gear housing while aligning injection pump shaft
through back of injection pump gear.
(7) After pump is positioned flat to mounting
flange, install 3 pump mounting nuts and tighten
finger tight only. Do not attempt a final tightening
at this time. Do not attempt to tighten (pull)
pump to gear housing using mounting nuts.
Damage to pump or gear cover may occur. The
pump must be positioned flat to its mounting
flange before attempting to tighten 3 mounting
nuts.
(8) To prevent damage or cracking of components,
install and tighten nuts in the following sequence:
(a) Install injection pump shaft washer and nut
to pump shaft. Tighten nut finger tight only.
(b) Do preliminary (light) tightening of injection
pump shaft nut.
(c) Tighten 3 injection pump mounting nuts to
24 N·m (18 ft. lbs.).

3/8" drive ratchet. Plate is threaded to timing gear
cover. Tighten to 8 N·m (71 in. lbs.) torque.
(10) Install fuel line (injection pump-to-pressure
limiting valve). Tighten bolts to 24 N·m (18 ft. lbs.)
torque.
(11) Install fuel line (injection pump-to-fuel rail).
(a) Tighten fitting at fuel pump to 37 N·m (27 ft.
lbs.) torque. Use a back-up wrench.
(b) Tighten fitting at fuel rail to 37 N·m (27 ft.
lbs.) torque.
(12) Install fuel line (injection pump-to-fuel filter
housing). Tighten to 24 N·m (18 ft. lbs.) torque.
(13) Connect Fuel Control Actuator (FCA) electri-
cal connector to rear of injection pump.
(14) Install intake manifold air intake tube (above
injection pump). Tighten clamps.
(15) Install accessory drive belt.
(16) Install cooling fan shroud.
(17) Install cooling fan assembly.
(18) Connect both negative battery cables to both
