Hydrostatic Transmission Cooling Fins
Keeping the cooling fins on the hydrostatic transmis-
sions clean and free of obstruction is
essential to
avoid overheating
the transmission fluid and short-
ening transmission life. The cooling fins should be
checked
every 100 hours;
and cleaned if necessary.
To clean the fins, use compressed air and/or a
pressure washer. The cooling fins extend all the
way around the housing -- the fins underneath need
to be clean as well as the more visible fins 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
fins 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.
