Figure 43. Air Cleaner Removal
The Deutz 2011 Series Engine uses a robust, heavy duty oil
cooler system to cool the engine. The cooling system will benefit
from periodic inspection and cleaning.
1. Disconnect the Air Intake Hose. Remove the three nuts
and torx screws (Item 1, Figure 43).
2. Remove 3 bolts that mount the air filter bracket to the engine,
(item 2) and the two bolts holding the Lifting Bale (Item 3).
3. Remove the Air Box (Item 4) and Lifting Bale as a unit,
exposing the oil cooler unit.
4. Use a nylon bristle brush to gently brush the underside of
the oil cover to break loose any accumulated dirt and debris.
5. Using compressed air, carefully blow from the top of the oil
cooler to remove lodged dirt and debris. Blow out any dirt
out of the Air Box.
6. Use compressed air to next blow accumulated dirt and
debris from the Fan Air Intake, Fan, and Fan Tunnel.
7. Using a non-caustic degreasing agent, soak entire oil cooler
and let sit for several minutes. With low pressure water,
such as a garden hose with a spray nozzle, thoroughly
rinse Oil Cooler and Air Box out.
8. Re-install Air Box Cover, Air Filter Assembly and mount,
and tighten Air Intake Hose connector.
