Fuel Injection Nozzles - Test/Exchange; Every 1000 Service Hours Engine Valve Lash - Inspect/Adjust - Perkins 1106E Operation And Maintenance Manual

Engine Valve Lash -
Inspect/Adjust
This maintenance is recommended by Perkins as
part of a lubrication and preventive maintenance
schedule in order to help provide maximum engine
life.
NOTICE
Only qualified service personel should perform this
maintenance. Refer to the Service Manual or your au-
thorized Perkins dealer or your Perkins distruibutor for
the complete valve lash adjustment procedure.
Operation of Perkins engines with incorrect valve lash
can reduce engine efficiency, and also reduce engine
component life.
Ensure that the engine can not be started while
this maintenance is being performed. To help pre-
vent possible injury, do not use the starting motor
to turn the flywheel.
Hot engine components can cause burns. Allow
additional time for the engine to cool before mea-
suring/adjusting valve lash clearance.
Ensure that the engine is stopped before measuring
the valve lash. The engine valve lash can be
inspected and adjusted when the temperature of the
engine is hot or cold.
Refer to Systems Operation/Testing and Adjusting,
"Engine Valve Lash - Inspect/Adjust" for more
information.

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 discon-
nected fuel system component.
If a fuel injector nozzle is suspected of operating out-
side of normal parameters it should be removed by a
qualified technician. The suspect fuel injector nozzle
should be taken to an authorised agent for inspection.
Regular maintenance of the fuel injector nozzles
is not necessary. The fuel injector nozzles should
not be cleaned as cleaning with incorrect tools can
damage the nozzle. The fuel injector nozzles should
be renewed only if a fault with the fuel injection nozzle
occurs. Some of the problems that may indicate
that new fuel injection nozzles 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
•
The engine knocks or there is vibration in the
engine.
•
Excessive engine temperature
