Engine Mounts - Inspect
Test the Service Indicator
Service indicators are important instruments.
• Check for ease of resetting. The service indicator
should reset in less than three pushes.
• Check the movement of the service indicator core
when the engine is run at full load speed. The core
should latch approximately at the greatest vacuum
that is attained.
If the service indicator does not reset easily, or if the
core does not latch at the greatest vacuum, the
service indicator should be replaced. If the new
service indicator will not reset, the hole for the service
indicator may be plugged.
If necessary, replace the service indicator more
frequently in environments that are severely dusty.
Replace the service indicator annually regardless of
the operating conditions. Replace the service
indicator when the engine is overhauled, and
whenever major engine components are replaced.
Note: When a new service indicator is installed,
excessive force may crack the top of the service
indicator. Tighten the service indicator to a torque of
2 N·m (18 lb in).
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.
