Typical example
Ensure that the engine is stopped. Ensure that the
battery disconnect switch is in the OFF position.
Ensure that the cooling system is full.
The clearance between the cover (2) and the fan (1)
will require checking. The gap between the edge of
the cover and the tip of the fan blade (A) must be
checked in four equally spaced positions.
Note:
The cover is not adjustable.
Three Cylinder
• (A) equals 5 mm (0.19685 inch) for the three
cylinder engine
Four Cylinder Turbocharged
• (A) equals 10 mm (0.39370 inch) for the
turbocharged engine.

Fuel Injector - Test/Change
Fuel leaked or spilled onto hot surfaces or electri-
cal components can cause a fire.
Make sure that you wear eye protection at all
times during testing. When fuel injection nozzles
are tested, test fluids travel through the orifices
of the nozzle tip with high pressure. Under this
amount of pressure, the test fluid can pierce the
skin and cause serious injury to the operator. Al-
ways keep the tip of the fuel injection nozzle
pointed away from the operator and into the fuel
collector and extension.
NOTICE
Do not allow dirt to enter the fuel system. Thoroughly
clean the area around a fuel system component that
will be disconnected. Fit a suitable cover over any
disconnected fuel system components.
Regular maintenance of the fuel injectors is
recommended by Perkins. The fuel injectors must be
removed and tested by an authorized agent. The fuel
injectors should not be cleaned as cleaning with
incorrect tools can damage the nozzle. The fuel
injectors should be renewed only if a fault with the
fuel injectors occurs. Some of the problems that may
indicate that new fuel injectors are needed are listed
below:
• The engine will not start or the engine is difficult to
start.
• Not enough power
• The engine misfires or the engine runs erratically.
• High fuel consumption
• Black exhaust smoke
