Cleaning Primary Filter Element
Numbers in parentheses refer to Fig. 3.
Although a paper primary filter element (5) is used, it is
possible to remove excess dirt by tapping element.
The number of times one element can be reused
depends on the type of dirt on it and the care exercised
in cleaning. Element damage will be indicated by areas
of concentrated dust on the clean side of the element.
If in doubt - always fit a new element.
1. Release latches on cover assembly (1) and remove
cover assembly from air cleaner body (10).
2. Remove primary element (5) from air cleaner body
(10) and clean/replace. It is advised to replace the
element rather than attempt to clean thoroughly.
3. Install primary element (5) in air cleaner body (10).
4. Install cover assembly (1) on air cleaner body (10)
and secure with latches.
Secondary (Safety) Filter Element
Numbers in parentheses refer to Fig. 3.
The secondary (safety) filter element (8) is installed in
the air cleaner body (10) and inside of the primary filter
element (5). This secondary (safety) element increases
Engine - Air Cleaner
the reliability of the air cleaner’s protection of the
engine from airborne dirt. It protects the engine from
dirt admitted by a damaged primary filter element (5),
or dirt that might be dropped into the air cleaner body
(10) while changing the primary filter element (5). Since
the secondary (safety) filter element (8) is protected
from contamination by the primary filter element (5) it
needs no periodic cleaning but should be replaced
when it affects the total air flow restriction of the air
cleaner, or on at least every third primary filter element
service.
Note: Do not clean secondary (safety) filter element -
replace with a new element.
Secondary (Safety) Filter Element
Removal
Numbers in parentheses refer to Fig. 3.
1. Remove secondary (safety) filter element (8) by
removing cotter pin (7) and then loosen nut (6).
Remove nut (6) and gasket (4), then lift out element.
2. Wipe clean inside of air cleaner body (10) using a
damp cloth. Check all body gaskets are properly
secured and in good condition. Also check cleaner
body (10) for cracks or other structural damage.
Replace damaged parts immediately.
3. Check all new or properly serviced components for
damage prior to installing in the cleaner body. Always
check new filter element part numbers against air
cleaner information label.
RECOMMENDATIONS
1. Under no condition should the unit be operated
without both filter elements.
2. Carbon, soot and oil fumes will quickly hamper the
operation of the paper filter element. Keep air cleaner
inlet as far away as possible from sources of theses
products, such as a parked vehicle with engine
running. Also, make sure that the engine exhaust
system does not leak, to prevent fouling the element
with soot .
3. Keep new or cleaned filter elements on hand for
replacement to prevent unnecessary vehicle downtime.
