Perkins 1104D Operation And Maintenance Manual page 81

SEBU8172-04
Periodic cleaning of the engine is recommended.
Steam cleaning the engine will remove accumulated
oil and grease. A clean engine provides the following
benefits:
• Easy detection of fluid leaks
• Maximum heat transfer characteristics
• Ease of maintenance
Note: Caution must be used in order to prevent
electrical components from being damaged by
excessive water when the engine is cleaned.
Pressure washers and steam cleaners should not be
directed at any electrical connectors or the junction of
cables into the rear of the connectors. Avoid
electrical components such as the alternator, the
starter, and the ECM. Protect the fuel injection pump
from fluids in order to wash the engine.
Engine Air Cleaner Element
(Dual Element) - Clean/Replace
NOTICE
Never run the engine without an air cleaner element
installed. Never run the engine with a damaged air
cleaner element. Do not use air cleaner elements
with damaged pleats, gaskets or seals. Dirt entering
the engine causes premature wear and damage to
engine components. Air cleaner elements help to pre-
vent airborne debris from entering the air inlet.
NOTICE
Never service the air cleaner element with the engine
running since this will allow dirt to enter the engine.
Servicing the Air Cleaner Elements
Note: The air filter system may not have been
provided by Perkins. The procedure that follows is for
a typical air filter system. Refer to the OEM
information for the correct procedure.
If the air cleaner element becomes plugged, the air
can split the material of the air cleaner element.
Unfiltered air will drastically accelerate internal
engine wear. Refer to the OEM information for the
correct air cleaner elements for your application.
• Check the precleaner (if equipped) and the dust
bowl daily for accumulation of dirt and debris.
Remove any dirt and debris, as needed.
• Operating in dirty conditions may require more
frequent service of the air cleaner element.
Engine Air Cleaner Element (Dual Element) - Clean/Replace
• The air cleaner element should be replaced at
least one time per year. This replacement should
be performed regardless of the number of
cleanings.
Replace the dirty air cleaner elements with clean air
cleaner elements. Before installation, the air cleaner
elements should be thoroughly checked for tears
and/or holes in the filter material. Inspect the gasket
or the seal of the air cleaner element for damage.
Maintain a supply of suitable air cleaner elements for
replacement purposes.
Dual Element Air Cleaners
The dual element air cleaner contains a primary air
cleaner element and a secondary air cleaner
element.
The primary air cleaner element can be used up to
six times if the element is properly cleaned and
properly inspected. The primary air cleaner element
i02334355 should be replaced at least one time per year. This
replacement should be performed regardless of the
number of cleanings.
The secondary air cleaner element is not serviceable.
Refer to the OEM information for instructions in order
to replace the secondary air cleaner element.
When the engine is operating in environments that
are dusty or dirty, air cleaner elements may require
more frequent replacement.
