5.6. AIR CLEANING SYSTEM
5.6.1. AIR CLEANER
This machine has a "dry-type" cleaner with replaceable elements.
The cleaner has two elements: primary and safety. The primary element can be cleaned for a
limited number of times before replacement is necessary. However, the safety element must be
replaced when plugged. Detailed service procedures for this air cleaner are covered in the
following text.
IMPORTANT: As a precaution against dirt entering the engine, all gasket and rubber hoses
between the air cleaner, turbocharger and intake manifold, and between the manifold and cylinder
head must be in good condition and the joints or connections must be tight. Never operate the
engine unless a filter element is in place and filter end gasket is installed. Never remove the
element from the air cleaner or service the air cleaner while the engine is running.
5.6.2. PRIMARY FILTER ELEMENT
Service
The air cleaner primary element must be serviced whenever indicated by the air cleaner filter
warning light. Refer to "AIR CLEANER FILTER WARNING LIGHT", Section 4.
If after performed cleaning of the primary filter element the air cleaner filter warning light continues
to glow, check the pre-cleaner screen for allowable restriction. If the warning light continues to
glow, replace safety filter element. If, with cleaned primary filter element and replaced safety filter
element, the warning light still continues to glow check the air cleaner service indicator. The
primary element can be cleaned by either of two methods: washing or cleaning with compressed
air. Washing is the preferred method as it removes more dust and soot and restores the element
to an almost new condition.
The result being better performance and longer intervals between required element service. It is
recommended that a spare element be obtained for use while the serviced element is drying.
NOTE: The primary filter element must be replaced after six washings.
Cleaning the element with compressed air is not considered an entirely satisfactory method. Some
dust will remain in the element causing more frequent servicing of the element. Cleaning with
compressed air should be used only as a temporary measure until sufficient time is available to
clean the element by washing.
NOTE: After cleaning, if an element is to be stored for later use, place it in a plastic bag and store
in an element-shipping container to protect against dirt and damage.
Removal (Fig. 5.2)
1. Open the left engine access door. Remove all dust from the element removable end of air
cleaner body (8).
2. Loosen the wing nut and remove cover (1) and seal ring (2) from air cleaner body (8).
3. Unscrew wing nut (3) and carefully remove primary element (4) from the body not to dislodge
dust from the dirty element onto safety element (7).
4. Check the condition of the seal at the end of primary element (4). If the seal is damaged or
missing, replace the primary element.
5. Remove all dirt from inside air cleaner body (8) with a damp cloth. A small amount of
nonsudsing detergent added to the water will remove the soot.
