Cooling Fan Circuit − Fan Motor Case Drain Leakage
Test
Over a period of time, the motor can wear internally. This
test measures case drain volume while restricting flow
across the motor ports. Case drain volume under load
of more than 12% of total motor flow indicates the gears
and wear plates in the motor have worn. A worn motor
may by−pass hydraulic fluid to its case drain causing the
motor to be less efficient. Eventually, enough fluid loss
will cause the fan motor to slow, reducing its ability to
cool the engine. Continued operation with a worn, ineffi-
cient motor can generate excessive heat, cause dam-
age to seals and other components in the hydraulic
system, and affect engine performance.
Special Equipment Required:
S 15 GPM (56 LPM) Hydraulic Tester (Pressure
and Flow) with hoses − 13/16 − 16
S Hydraulic Hose − 11/16 − 16 x 6 ft (1.8 m)
S Phototach (non−contact tachometer)
1. Park the machine on a level surface with the cutting
units lowered and the reel enable/disable switch in the
DISABLE position. Make sure engine is off and the park-
ing brake is engaged.
CAUTION
Prevent personal injury and/or damage to equip-
ment. Read all WARNINGS, CAUTIONS and Pre-
cautions for Hydraulic Testing at the beginning
of this section.
2. Raise and support hood to gain access to fan shroud
and fan motor plumbing.
IMPORTANT: Make sure that the oil flow indicator
on the tester matches the flow of oil (fan shroud up-
per bulkhead fitting > tester > fan control manifold).
3. Disconnect the return tube from the fan shroud (up-
per tube) and the fan control manifold M2 port. Remove
the hydraulic tube and install a hydraulic tester and hose
between the fan shroud bulkhead fitting and the fan con-
trol manifold. Make sure the tester flow control valve is
fully open.
4. Start engine and run at low idle speed. Check for hy-
draulic leaks at tester connections and make correc-
tions if necessary before proceeding with test.

2. Proportional relief valve

5. Set throttle to high speed.
A. Use the InfoCenter display to verify engine RPM
on units with Yanmar diesel engines (2850 RPM).
B. Use a phototach to verify engine RPM on units
with Kubota diesel engines (2850 +50/−120 RPM).
6. Make sure hydraulic oil is at normal operating tem-
perature by operating the machine for approximately ten
(10) minutes.
7. Stop the engine and disconnect the wire harness
connector from the proportional relief valve solenoid at
fan control manifold port TS (Fig. 44).
8. Disconnect the case drain tube from the motor (small
diameter center tube at fan shroud) and install a 6 ft (1.8
m) hydraulic hose to the fan shroud bulkhead fitting. Put
a steel plug on the disconnected tube to prevent system
contamination.
9. Place open end of the case drain test hose into a
drain pan.
10.Two people are required to complete the following
steps. One person should sit in the operator’s seat and
operate the machine while another person reads the
tester and measures fan motor case drain volume.
