NOTE: If machine is
TM
CrossTrax AWD, jack up and support the rear wheels
off the ground to allow flow through the rear wheel mo-
tors.
6. Thoroughly clean junction of hydraulic hose and
right side elbow fitting on bottom of piston (traction)
pump (Fig. 36). Disconnect hose from piston (traction)
pump fitting.
IMPORTANT: Make sure that the oil flow indicator
arrow on the flow meter is showing that the oil will
flow from the pump, through the tester and into the
hydraulic hose.
7. Install tester with pressure gauges and flow meter in
series with the piston (traction) pump and the discon-
nected hose. Make sure the tester flow control valve
is fully open.
8. Start engine and increase engine speed to high idle
speed (3000 RPM). Make sure hydraulic oil is at normal
operating temperature by operating the machine under
load for approximately ten (10) minutes.
CAUTION
Use extreme caution when performing test. The
front tires on the ground will be trying to move
the machine forward.
9. Fully apply the brakes to prevent the front wheels
from rotating and slowly push traction pedal in forward
direction until 1000 PSI is displayed on the tester pres-
sure gauge.
10.Combined front wheel motor internal leakage will be
shown on flow meter in GPM (LPM).
11. Release traction pedal, release brake pedal, shut
engine off, rotate both front wheels and retest. Testing
of wheel motor leakage in three (3) different wheel posi-
tions will provide the most accurate test results. Record
measured front wheel motor internal leakage for all
three (3) wheel positions.
12.If combined leakage for the front wheel motors is
less than 1.5 GPM (5.7 LPM), consider that the front
wheel motors are in good condition. If combined leak-
age for the front wheel motors is more than 1.5 GPM
(5.7 LPM), one or both of the motors may be faulty. Indi-
vidual front wheel motor testing is necessary.

13.To test individual front wheel motors:
A. Remove front wheel from wheel motor that is not
being tested. Remove wheel shield to allow access
to hydraulic tubes and fittings on wheel motor. Re-
move fasteners that secure front hydraulic tube r-
clamps to frame.
B. On the front wheel motor that is not being tested,
thoroughly clean junction of both hydraulic tubes and
wheel motor fittings. Disconnect both hydraulic lines
from wheel motor that is not being tested. Install a
steel cap on disconnected hydraulic lines and wheel
motor fittings.
C. Use the procedure described in steps 8 to 10
above to identify individual front wheel motor leak-
age. Individual motor internal leakage will be shown
on flow meter in GPM (LPM). Flow should be less
than 1.5 GPM (5.7 LPM) for the tested wheel motor.
If leakage for the tested motor is more than 1.5 GPM
(5.7 LPM), the tested motor is faulty.
D. If other front wheel motor requires testing, com-
plete steps A, B and C for remaining wheel motor.
14.After testing is completed, stop engine and then re-
lieve hydraulic system pressure (See Relieving Hydrau-
lic System Pressure in the General Information section
of this chapter). Disconnect tester from hydraulic fitting
and hose. Connect hose to pump elbow fitting. Remove
caps from hydraulic tubes and reconnect tubes to wheel
motor. Secure hydraulic tubes to machine with r- clamps
and removed fasteners. Install wheel shield and
wheel(s) (see Wheels in the Service and Repairs sec-
tion of Chapter 6 - Chassis).
