Start By:
a. Remove the valve mechanism cover. Refer to
Disassembly and Assembly, “Valve Mechanism
Cover - Remove and Install”.
Note: Either Tooling (A) can be used. Use the Tooling
that is most suitable.
Contact with high pressure fuel may cause fl uid
penetration and burn hazards. High pressure fu-
el spray may cause a fi re hazard. Failure to fol-
low these inspection, maintenance and service in-
structions may cause personal injury or death.
NOTICE
Ensure that all adjustments and repairs that are
carried out to the fuel system are performed by
authorised personnel that have the correct train-
ing.
Before begining ANY work on the fuel system, re-
fer to Operation and Maintenance Manual, “Gen-
eral Hazard Information and High Pressure Fuel
Lines” for safety information.
Refer to Systems Operation, Testing and Adjust-
ing Manual, “Cleanliness of Fuel System Compo-

NOTICE
Care must be taken to ensure that fl uids are contained
during performance of inspection, maintenance, test-
ing, adjusting and repair of the product. Be prepared to
collect the fl uid with suitable containers before open-
ing any compartment or disassembling any compo-
nent containing fl uids.
Dispose of all fl uids according to local regulations and
mandates.
NOTICE
Use a deep socket in order to remove the electrical
connections from the electronic unit injectors. Use of
incorrect tooling will result in damage to the electronic
unit injectors.
Note: Put identi fi cation marks on all hoses, on all
hose assemblies, on wires and on all tube assemblies
for installation purposes. Plug all hose assemblies
and tube assemblies. This helps to prevent fl uid loss
and this helps to keep contaminants from entering
