7.
Remove the joint from the lift pump (2). Discard the
joint.
Installation of the Lift Pump
1.
Install a new joint to the lift pump (2).
2.
Align the drive for the lift pump (2). Install the lift
pump.
Note:
Ensure that the oil seal is not damaged as the
lift pump is installed.
3.
Install the nuts (4). Tighten the nuts to a torque of
25 N·m (18 lb ft).
4.
Remove the cap from the fuel line (3). Connect the
fuel line and the connection (1). Tighten the fuel
line and the connection to a torque of 50 N·m
(37 lb ft).
5.
Fit the fuel priming pump (5) to the lift pump (2).
6.
Restore the fuel supply to the lift pump.
7.
Remove the air from the fuel system. Refer to
Operation and Maintenance Manual, “Fuel System
- Prime”.

Governor Actuator - Check
In order for the governor to operate correctly, the
control box must be calibrated to the actuator. The
feedback parameters from the control box must
correspond to the 0% and the 100% positions on the
actuator. Carry out a periodic calibration check of the
governor system. Refer to Special Instruction,
“Pandoras Digital Governor” for more information.

Inspect/

Contact with high pressure fuel may cause fluid
penetration and burn hazards. High pressure fuel
spray may cause a fire hazard. Failure to follow
these inspection, maintenance and service in-
structions may cause personal injury or death.
If you inspect the engine in operation, always use the
proper inspection procedure to avoid a fluid
penetration hazard. Refer to Operation and
Maintenance Manual, “General hazard Information”.
Inspect all hoses for leaks that are caused by the
following conditions:
• Cracking
• Softness
• Loose clamps
Replace hoses that are cracked or soft. Tighten any
loose clamps.
Check for the following conditions:
• End fittings that are damaged or leaking
• Outer covering that is chafed or cut
• Exposed wire that is used for reinforcement
• Outer covering that is ballooning locally
• Flexible part of the hose that is kinked or crushed
• Armoring that is embedded in the outer covering
A constant torque hose clamp can be used in place
of any standard hose clamp. Ensure that the constant
torque hose clamp is the same size as the standard
clamp.
Due to extreme temperature changes, the hose will
harden. Hardening of the hoses will cause hose
clamps to loosen. This action can result in leaks. A
constant torque hose clamp will help to prevent loose
hose clamps.
Each installation application can be different. The
differences depend on the following factors:
• Type of hose
• Type of fitting material
• Anticipated expansion and contraction of the hose
• Anticipated expansion and contraction of the
fittings
Replace the Hoses and the Clamps
Refer to the OEM information for further information
on removing and replacing fuel hoses (if equipped).
The coolant system and the hoses for the coolant
system are not usually supplied by Perkins. The
following text describes a typical method of replacing
coolant hoses. Refer to the OEM information for
further information on the coolant system and the
hoses for the coolant system.
