4. Apply a light coating of clean transmission oil to the
gasket of the new filter. Install the filter by turning
it clockwise, by hand, until the gasket contacts the
filter base on the transmission housing; then
tighten the filter an additional 1/2 turn.
5. Clean the area around the transmission oil fill
plug/dipstick to prevent debris from entering the
transmission case.
6. Remove the oil fill plug/dipstick from the oil fill port
and SLOWLY pour oil into the oil fill port. Fill the
transmission case until the oil level reaches the
"FULL" mark on the dipstick (Refer to Figure 22).
7. Reinstall the oil fill plug/dipstick securely into the
oil fill port.
8. Start the engine and allow it to run for a few
minutes. Shut the engine off, then check for leaks
and re-check the oil level in the transmission case.
CAUTION
The oil fill plug/dipstick must be installed
securely into the fill port at all times when
the engine is operating.
AIR CLEANER
Check the air cleaner daily or before starting the
engine. Check for loose or damaged components and
check the condition of the filter element. Remove any
buildup of dirt and debris in the air cleaner housing.
NOTE
Operating the engine with loose or damaged air
cleaner components will allow unfiltered air into
the carburetor, causing extensive wear and
eventual failure of the engine.
Servicing the Precleaner
Wash the foam precleaner after every 25 hours of
operation (more often under extremely dusty or dirty
conditions).
1. Unhook the clips on both sides of the air cleaner
cover and remove the air cleaner cover (See
Figure 26).
2. Remove the foam precleaner by sliding it up off the
paper element (See Figure 26).
3. Wash the precleaner in warm water with
detergent. Rinse the precleaner thoroughly until all
traces of the detergent are eliminated. Squeeze
out (do not wring) excess water in a dry cloth.
Allow the precleaner to air dry.
Figure 26. Air Cleaner Assembly.
4. Reinstall the foam precleaner over the paper
element.
5. Reinstall the air cleaner cover and reattach the
cover clips to both sides of the air cleaner body.
Servicing the Paper Element
Every 100 hours of operation (more often under
extremely dusty or dirty conditions), inspect the paper
element. Replace the element as necessary.
1. Unhook the clips on both sides of the air cleaner
cover and remove the air cleaner cover (See
Figure 26).
2. Remove the foam precleaner by sliding it up off the
paper element (See Figure 26).
3. Remove the knob and element cover plate, then
carefully lift out the paper air filter element to
prevent debris from entering the carburetor.
4. Do not wash the paper element or use pressurized
air, as this will damage the element. Replace a
dirty, bent or damaged element. Handle new
elements carefully; do not use if the sealing
surfaces are bent or damaged.
5. When servicing the air cleaner, check the air
cleaner body. Make sure it is secured and not bent
or damaged. Also check the element cover plate
for damage or improper fit. Replace all damaged
air cleaner components.
6. Reinstall the paper element, foam precleaner,
cover plate and knob. Reinstall the air cleaner
cover and reattach the cover clips to both sides of
the air cleaner body.
Properly cleaned and installed air cleaner elements
significantly contribute to prolonging engine life.
