to Remove GHS Blower Drive Belt
IMPORTANT: With the belt removed, the
blow er wheel must spin freely. Any binding
or drag ging of the wheel is an indication of dirt
buildup. This buildup must be cleaned to
avoid abrasive wear of the blower blades,
ex cessive power loss and eventual loss of
blower performance (clogging).
2. Use a pressure washer or water spray, and
di rect the spray inside the blower housing
against the blower blades. Water pressure will
cause the blower wheel to begin to spin and
the com bination of spinning action and water
will e󰀨ec tively wash the inside of the housing.
Spray may be directed against the blower
blades ver tically and horizontally to cause
rotation in both directions for thorough wash-
ing action. Wash blower until the blower
wheel spins freely in both directions.
3. Reinstall the GHS blower drive belt by revers-
ing the removal procedure.

Hydrostatic Transmission Cooling Fins
Keeping the cooling ns on the hydrostatic trans-
missions clean and free of obstruction is essential
to avoid overheating the transmission uid and
shortening transmission life. The cooling ns
should be checked every 100 hours and cleaned
if necessary.
To clean the ns, use compressed air and/or a
pressure washer. The cooling ns extend all the
way around the housing–the ns underneath need
to be clean as well as the more visible ns above.
Also, pay close attention to the area under the
drive pul ley.
IMPORTANT: In case an oil leak develops on the
input shaft, the cooling fan blowing dusty air and oil
on the transmission will quickly pack the cooling
ns with oily dirt. If this condition occurs, replace
the seal immediately to avoid overheating and
dam aging the transmission. The input shaft
assembly and seal are easily replaced without
removing the transmission from the machine.
An additional procedure in maintaining transmis-
sion cooling is to inspect the cooling fans. Replace
the fan(s) if blades are missing or damaged.
