Engine Mounts - Inspect
Note: The engine mounts may not have been
supplied by Perkins. Refer to the Original Equipment
Manufacturer (OEM) information for further details on
the engine mounts and the correct bolt torque.
Inspect the engine mounts for deterioration and for
correct bolt torque. Excessive engine vibration can
be caused by the following conditions:
• Incorrect mounting of the engine
• Deterioration of the engine mounts
• Loose engine mounts
Any engine mount that shows deterioration should be
replaced. Refer to the OEM information for the
recommended torques.
When the engine mounts are supplied by Perkins the
maintenance procedure will be supplied in the
Disassembly and Assembly manual for your engine.

Engine Oil Level - Check
Hot oil and hot components can cause personal
injury. Do not allow hot oil or hot components to
contact the skin.

(Y) “ADD” mark. (X) “FULL” mark.
NOTICE
Perform this maintenance with the engine stopped.
1. Maintain the oil level between “ADD” mark (Y) and
“FULL” mark (X) on oil level gauge (1). Do not fill
the crankcase above “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 or en-
gine failure.
2. Remove the oil filler cap and add oil, if necessary.
Clean the oil filler cap. Install the oil filler cap.
