Hydrostatic Transmission Cooling Fins
Keeping the cooling ns on the hydrostatic transmis-
sions clean and free of obstruction is essential to
avoid overheating the transmission uid and short-
ening 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
pulley.
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 transmission
cooling is to inspect the cooling fans. Replace the
fan(s) if blades are missing or damaged.
