CLEANING
Engine Air Cleaner System
There are two main components in the engine air
cleaner system: a turbine precleaner and a Donald-
son Radialseal™ air cleaner. Each component is
checked, cleaned and maintained on a different
schedule based on the filtering action required.
Each component is serviced as follows:
Turbine Precleaner
The turbine precleaner is mounted on a remote air
intake tube connected to the Donaldson air cleaner.
A spinning fan driven by the intake airflow separates
dust from the air, giving the initial stage of air clean-
ing. Dust particles are exhausted through a single
small vent in the side of the housing. Since no dust
is trapped, the precleaner operates without clean-
ing. The only maintenance required is to check the
operation of the internal fan every 100 hours. Verify
operation:
1. Look into the exhaust vent while shining a light
into the intake.
2. Start the engine and watch the fan begin to spin
as the throttle is advanced.
If the fan is not spinning, service or replace the pre-
cleaner as required.
