Engine Ground - Inspect/Clean
Inspect the wiring harness for good connections.
Perkins use the starter motor in order to ground the
engine. Check the connection on the starter motor at
every oil change. Ground wires and straps should be
combined at engine grounds. All grounds should be
tight and free of corrosion.
• Clean the grounding stud on the starter motor and
the terminals with a clean cloth.
• If the connections are corroded, clean the
connections with a solution of baking soda and
water.
• Keep the grounding stud and the strap clean and
coated with suitable grease or petroleum jelly.

Engine Mounts - Inspect
Note: The engine mounts may not have been
supplied for this installation by Perkins. Refer to the
OEM information for further information on the engine
mounts and the correct bolt torque.
Inspect the engine mounts for deterioration and for
correct bolt torque. Engine vibration can be caused
by the following conditions:
• Incorrect mounting of the engine
• Deterioration of the engine mounts
Any engine mount that shows deterioration should
be replaced. Refer to the OEM information for the
recommended torques .

(Y) "ADD" mark. (X) "FULL" mark .
NOTICE
Perform this maintenance with the engine stopped.
Note: Ensure that the engine is either level or that
the engine is in the normal operating position in order
to obtain a true level indication.
Note: After the engine has been switched OFF, allow
the engine oil to drain to the oil pan before checking
the oil level.
1. Maintain the oil level between the "ADD" mark (Y)
and the "FULL" mark (X) on the engine oil dipstick.
Do not fill the crankcase above the "FULL" mark
(X).
NOTICE
Operating your engine when the oil level is above the
"FULL" mark could cause your crankshaft to dip into
the oil. The air bubbles created from the crankshaft
dipping into the oil reduces the oil's lubricating char-
acteristics and could result in the loss of power.
2. Remove the oil filler cap and add oil , if necessary.
Clean the oil filler cap. Install the oil filler cap.

Engine Oil Sample - Obtain
The condition of the engine lubricating oil may be
checked at regular intervals as part of a preventive
maintenance program. Perkins include an oil
sampling valve as an option. The oil sampling valve
(if equipped) is included in order to regularly sample
the engine lubricating oil. The oil sampling valve is
positioned on the oil filter head or the oil sampling
valve is positioned on the cylinder block.
Perkins recommends using a sampling valve in order
to obtain oil samples. The quality and the consistency
of the samples are better when a sampling valve is
used . The location of the sampling valve allows oil
that is flowing under pressure to be obtained during
normal engine operation.
