NOTICE
During testing, abnormal operating conditions must
be simulated.
The tests must be performed correctly in order to pre-
vent possible damage to the engine.
To prevent damage to the engine, only authorized
service personnel or your Perkins dealer should
perform the tests.
Visual Inspection
Visually check the condition of all gauges, sensors
and wiring. Look for wiring and components that are

(Valves
and
Valve
Bridges)
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 cannot 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.
Note: The valve bridges must be equalized before
the valve lash is adjusted.
Refer to Systems Operation, Testing and Adjusting,
“Valve Lash - Adjust” for the correct procedure.
