Engine Valve Lash - Inspect/Adjust

5. Some dipstick could be marked with a "H" and "L" ,

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 Control Linkage - Check/
Lubricate
Do not work on the engine unless the instructions
and warnings are understood. Refer to the safety
section in this Operation and Maintenance Manual for
more information.
Perkins recommends a scheduled inspection of the
fuel control linkage for the fuel injection pump for
loose components and free movement of the linkage
.The fuel control linkage for the fuel injection pump
and solenoid ball joint plunger is lubricated at defined
intervals.
To maximize the engine performance, check the fuel
i02171102
control linkage for wear, secure installation, and
unrestricted movement of the mechanism. Ensure
that the fuel control linkage is sufficiently lubricated.
Check
Accidental engine starting can cause injury or
death to personnel working on the equipment.
To avoid accidental engine starting, disconnect
the battery cable from the negative (−) battery ter-
minal. Completely tape all metal surfaces of the
disconnected battery cable end in order to pre-
vent contact with other metal surfaces which
could activate the engine electrical system.
Place a Do Not Operate tag at the Start/Stop
switch location to inform personnel that the
equipment is being worked on.
At a service interval of every 100 hours, perform the
following procedure:
