Air Cleaner and Air Intake System
To service the precleaner perform the following steps:
1. Remove the air cleaner cover knob (standard air
cleaner) or unsnap the latches (heavy-duty air
cleaner), and remove the cover/housing. See
Figures 4-3 and 4-4.
2. Remove the precleaner from the filter element. If
element is not secured to the air cleaner base with
a wing nut, remove the filter element and
precleaner from the cover/housing, as an
assembly before separating. See Figures 4-5 and
4-6.
3. Wash the precleaner in warm water with
detergent. Rinse the precleaner thoroughly until
all traces of detergent are eliminated. Squeeze out
excess water (do not wring). Allow the precleaner
to air dry.
4. Saturate the precleaner with new engine oil.
Squeeze out all excess oil.
5. Install the precleaner over the paper element. If
the element was not secured with a wing nut
(some heavy-duty air cleaners) install the
element/precleaner assembly, small end first, into
the cover/housing.
6. Reinstall the air cleaner cover/housing assembly.
Secure with the knob or latches.
