Tier 4 Final Engines
The Tier 4 Final engine air cleaner assembly consists of replaceable primary and secondary air filter
inside a plastic housing. It is designed to be maintained without tools. Refer to Table 2 to see the
necessary parts for the maintenance of the air cleaner. A definite time schedule for changing the
element cannot be determined because of varying operating conditions. Check the filter indicator
daily and change the element as required.
Air Filter Replacement
1. Turn off the unit battery switch and open the doors on the left side of the unit.
2. Remove the air flow straightener (Refer to Figure 1C: Tier 4 Final Engine Air Cleaner).
This is done by pulling on the latches on the left and right of the air cleaner assembly and
pulling the straightener away from the air cleaner.
3. Once the flow straightener is removed, the inlet cover is exposed. Remove the inlet cover by
unlatching the 4 metal latches on the right side of the cover and pulling the cover away from
the air cleaner.
4. The primary air filter can now be pulled out. Remove the primary air filter to expose the
secondary air filter.
5. Before removing the secondary air filter, make sure there is no debris left inside the air
cleaner. Remove and replace the secondary air filter if it is necessary. Replace it by pushing
the filter straight into the air cleaner housing until the gasket on the filter seats properly.
6. Replace the primary air filter by pushing the filter straight into the air cleaner housing until
the gasket seats properly.
7. Replace the air inlet cover by moving the cover into place and latching the four metal
latches.
8. Replace the air flow straightener by locating the plastic locking tabs and pressing firmly on
the cover to snap it in place.
