Engine Maintenance

Servicing the Air Cleaner

Service Interval: Every 50 hours—Clean the foam
and paper air filter elements. (Service
the air cleaner more frequently if
operating conditions are extremely
dusty or sandy.)
Every 100 hours—Replace the paper
air filter element.
Removing the Filters
1. Lower the loader arm, stop the engine, and remove
the key.
2. Open the hood.
3. Clean around the air cleaner to prevent dirt from
getting into the engine and causing damage.
4. Remove the wingnut from the air cleaner cover and
remove the cover (Figure 49).

7. Inspect the foam filter and replace if it is torn or
worn.
8. Inspect the paper filter for tears, an oily film, or
damage to the rubber seal and replace it if you find
any damage.
Cleaning the Filters
1. Wash the foam pre-filter in liquid soap and warm
water. When clean, rinse it thoroughly.
2. Allow the foam filter to dry thoroughly.
3. Dip the foam filter in clean engine oil, then squeeze
out the excess oil.
Important: Ensure that you thoroughly squeeze
out the oil. The engine will smoke if you leave
too much oil in the filter.
4. Lightly tap the paper filter on a flat surface to remove
dust and dirt or blow compressed air, not exceeding
30 psi (207 kPa), from the inside.
Important: Never clean the paper element by
brushing it or with liquids, such as solvent, gas,
or kerosene. Replace the paper element if it is
damaged, or cannot be cleaned thoroughly (i.e.,
after approximately 100 operating hours).
Installing the Filters
Important: To prevent engine damage, always
operate the engine with the complete foam and
paper air cleaner assembly installed.
1. Carefully slide the foam pre-filter onto the paper
filter (Figure 51).
2. Place the filter assembly onto the air cleaner base
and secure it with a wingnut (Figure 50).
3. Install the air cleaner cover and secure it with the
wingnut (Figure 49).
4. Close the hood.
