5. While watching flow and pressure gauges, slowy
push traction pedal into forward, until 5 GPM is ob ­
tained.
TESTER READINGS: At 5 GPM, pressure not to
exceed 400 PSI.
If pressure rises above 400 PSI, check:
A. For restriction in lines to or from rear motor.
B. For internal motor drag. If internal drag, remove
motor and repair as necessary.

5. While watching pressure gauges, slowly push traction
pedal into forward until 1000 PSI is obtained, read flow
gauge.
TESTER READINGS: GPM Flow — Not more than
2 GPM at 1000 PSI.
If flow reading is higher than 2 GPM, tester must be
connected in series between pressure line and individ­
ual wheel motor to isolate defective motor. Repeat steps
1 - 5 in above test for each motor.
