Hydraulic Motor Case Drain
High Output and Extra High Output (and some Standard)
fan motors are equipped with a case drain port. The case
drain is plumbed into the back end of the motor, opposite
the output shaft. The case drain allows excess heat and
pressure to escape the body of the motor. The case drain
is a flat faced coupler that plugs into a dedicated port on
the tractor. This allows the oil to free flow directly to the
tractor’s hydraulic oil reservoir. If case drain line port is
capped off this may result in damage to the motor’s shaft
seal.
Refer to your tractor’s manual or contact your dealer for
further information on the tractor drain kit.
When uncoupled, the coupler has a 10psi relief pressure.
Hydraulic flow requirements are as follows:
•
Standard turbofans: 6-7 gal/ minute
•
High output & Extra high output turbofans: 10-11
gal/minute
NOTE: Check the labeling on your turbofan to determine
if you have a standard, high output or extra high
output turbofan. As a general rule, planters with
8-15 rows have a high output turbofan, 16-rows
and larger use an extra high output turbofan.
