Element Cleaning
It is not recommended that filter elements be cleaned.
Cummins and most other manufacturers will not warrant a
cleaned air filter.
Air Cleaner Body
Before installing the filter element, remove foreign material
(leaves, lint or other foreign matter) that may have collected
inside the air cleaner body. Inspect the inside of the body for
dents or other damage that would interfere with air flow or
GROVE
with the fins on the element or inside the body. Repair any
body dents, being careful not to damage the sealing
surfaces. Be sure to clean the sealing surface of the outlet
tube and the inside of the outlet tube, taking care not to
damage the sealing area on the tube.
Precleaner
The precleaner (1, Figure 7-5) prevents large debris from
entering the air cleaner and should be cleaned periodically,
especially when working in severe dust conditions. Remove

the top half of the precleaner by releasing the two latches on
the sides of the precleaner. Remove all debris from inside
precleaner and reassemble.

Vacuator Valve
Vacuator valves (2, Figure 7-5) (Figure 7-6) are designed to
expel loose dust and dirt from the air cleaner body
automatically, thus lengthening the element service life. The
valve lips must point straight down and be kept free from
debris to operate effectively. Mud and chaff can lodge in
these lips periodically and hold them open during engine
operation.
