Re-filling the Crankcase with Oil

IMPORTANT: On models LT1042 & LT 1045, the engine (with oil filter) has a capacity of 1.5 liters (50.75 oz.). On models LT1046 & LT 1050, the engine (with oil filter) has a capacity of 2.0 liters (67.60 oz.) Do NOT overfill. Always check the level on the dipstick as instructed on page 19 before adding more oil.

NOTE: For the proper oil type, refer to the chart on page 19 of this manual.

•Clean the area around the oil fill tube to prevent debris from entering the crankcase.

•Slowly pour oil into the fill tube. Fill the crankcase until the oil level reaches the full (F) mark on the dipstick (Refer to Figure 14).

•Reinstall the oil fill cap/dipstick securely into the oil fill tube.

IMPORTANT: The oil fill cap/dipstick must be installed securely onto the tube at all times when the engine is operating. Severe engine damage could result from a failure to do so.

•Start the tractor engine and allow it to run for thirty seconds, then stop the engine and remove the ignition key.

•Check the oil level and add oil if necessary. Do not overfill the engine crankcase.

•Examine the area around the base of the oil fill tube, the oil filter adapter, and the oil drain valve for leaks before operating the tractor.

IMPORTANT: If leaks are present, have your engine serviced by your Cub Cadet dealer before operating the tractor.

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. 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.

•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 into the upper section of the air cleaner cover (Models LT1042 & LT1045).

•Reinstall the precleaner over the paper element (Models LT1046 & LT1050).

•Reinstall the air cleaner cover and tighten the knob(s) securely.

Service Paper Element

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(s) 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 (Models LT1046 & LT1050). 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.
