Engine Valve Lash - Check
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 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 meas-
uring/adjusting valve lash clearance.
Ensure that the engine is stopped before measuring
the valve lash. To obtain an accurate measurement,
allow the valves to cool before this maintenance is
performed.
Refer to Systems Operation, Testing, and Adjusting,
“Engine Valve Lash - Inspect/Adjust” for more
information.

Ensure that the engine is stopped. Ensure that the
cooling system is full. The clearance between the
cover (1) and the fan (2) will require checking. The
gap (A) between the edge of the cover and the tip of
the fan blade must be checked in four equally spaced
positions.
