Air Filter

The engine is equipped with a replaceable, high density paper air cleaner element and an oiled, foam precleaner which surrounds the paper element. See Figure 21. Always examine the air cleaner before starting the engine. Check for a buildup of dirt and debris around the air cleaner system. Keep this area clean. Also check for loose or damaged components. Replace all bent or damaged air cleaner components.

NOTE: Starting the tractor with loose or damaged air cleaner components could allow unfiltered air into the engine causing premature wear and failure.

Precleaner

Wash and re-oil the precleaner every 25 hours of operation if equipped, (more often under extremely dusty or dirty conditions).

•Loosen the air cleaner cover knob and remove the cover.

•Remove the precleaner from the paper element.

•Wash the precleaner in warm water with detergent. Rinse the precleaner thoroughly until all traces of detergent are eliminated. Squeeze out excess water (do not wring). Allow the precleaner to air dry.

•Saturate the precleaner with new engine oil. Squeeze out all excess oil.

•Reinstall the precleaner over the paper element.

•Reinstall the air cleaner cover and tighten the knob securely.

•When ordering replacement parts, use the accompanying Illustrated Parts manual, or the

Attachments & Accessories table found on page 32 of this manual.

Service Paper Element

NOTE: Refer to the Attachments & Accessories table found on page 32 of this manual for the proper air filter.

The paper element should be replaced at least every 100 hours of operation. Replace more frequently if the tractor is operated under extremely dusty conditions. To replace the paper element, proceed as follows:

•Loosen the air cleaner cover knob and remove the cover.

•Remove the short seal and wing nut. Then remove the air cleaner element with precleaner. Remove the precleaner from the element and service as instructed earlier in this section.

IMPORTANT:Do not wash the paper element or use pressurized air, as this will damage the element.

Examine the element and discard if dirt and/or damage is present.

NOTE: Handle new elements carefully; do not use if the sealing surfaces are bent or damaged.

•If any loose dirt or debris fell on the air cleaner base when the element was removed, carefully remove it and wipe the base clean. Be careful that none of it drops into the intake throat.

•Check the condition of the rubber seal on the air cleaner stud. If condition is questionable in any way, replace it with the new long seal packaged with the replacement element.

•Check the air cleaner base. Make sure it is secured and not damaged. Also check the air cleaner cover for damage or improper fit. Replace all damaged air cleaner components.

•Install the precleaner over the new paper element.

•Install the element (with precleaner) on the base and secure it with the wing nut.

•Install short seal onto the stud until it contacts the wing nut, then reinstall the cover and tighten the knob securely. Refer to Figure 21.

Spark Plug

Every 200 hours of operation, remove the spark plug, check its condition, and reset the gap or replace with a new plug as necessary.
