ROUTINE MAINTENANCE - AS REQUIRED
Check Air Cleaner Connections and Ducts for Leaks
Ensure that all the connections between the air cleaner and the engine are tight and sealed.
Checking and Removing the Air Cleaner Primary Element
Maintenance of the air cleaner is due only when the air cleaner restriction indicator light
(1, Figure 5-1) is illuminated. This indicates that the air cleaner is plugged and requires
attention.
Figure 5-1
The air cleaner is a dry-type with two elements. A primary element that is replaceable, or can
be cleaned, and a safety element that should only be replaced and never cleaned. The safety
element should be replaced after every third primary element cleaning or change.
NOTE: Dust that gets by the air cleaner system can often be detected by
looking for dust streaks on the air transfer tubing or just inside the intake
manifold inlet.
Engine damage.
Raw, unfiltered air can cause engine damage.
Never service the air cleaner while the engine is running.
