Engine Protective Devices -
Check
Visual Inspection
Visually check the condition of all gauges, sensors,
and wiring. Look for wiring and components that are
loose, broken, or damaged. Damaged wiring or
components should be repaired or replaced
immediately.
Calibration Check
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.
Alarms and shutoffs must function correctly. Alarms
provide timely warning to the operator. Shutoffs help
to prevent damage to the engine. Determination of
the good working order of the engine protective
devices is impossible during normal operation.
Malfunctions must be simulated in order to test the
engine protective devices. To prevent damage to the
engine, only authorized service personnel or your
Perkins distributor should perform the tests.
Consult your Perkins distributor or refer to the
Service Manual for more information.

Engine Valve Lash - Check
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.
NOTICE
Only qualified service personnel should perform this
maintenance.
Operation of the engines with incorrect valve lash
can reduce engine efficiency, and also reduce engine
component life.
This maintenance is recommended as part of a
lubrication and preventive maintenance schedule in
order to help provide maximum engine life. The
maintenance for the valve lash is important in order
to keep the engine compliant.
Ensure that the engine is stopped before measuring
the valve lash. The engine valve lash can be
inspected and adjusted when the engine is cold.
• Inlet valve 0.20 mm (0.8 inch)
• Exhaust valve 0.20 mm (0.8 inch)
Refer to Systems Operation, Testing and Adjusting,
“Engine Valve Lash - Inspect/Adjust” for the correct
sequence of adjustment.
