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 distributor 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
measuring/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.
Fuel Injector - Test/Change
Fuel leaked or spilled onto hot surfaces or electri-
cal components can cause a fire.
