Testing
Rev. E
TEST HOOK UP NO.2
(continued)
TESTER READINGS
Pressure should not exceed 400 PSI.
If higher reading is obtained, check hydraulic line to and from motor for restriction. If no restriction, remove
wheel and brake drum. Repeat test.
If pressure is still excessive, remove traction motor and repair as necessary.
Repeat the test for the opposite wheel if required.
NOTE: Reconnect brake control rod after each test is completed.
TEST B: VALVE BANK LEAKAGE
PROCEDURE
Disconnect both hydraulic hoses that lead to left front wheel motor from hydraulic tubes on left side of machine. Cap
open ends of tubes and hoses.
Block up the machine so traction wheels are off floor. If machine is equipped with 3WD, rear wheel needs to be
off floor as well.
Disconnect brake control rod on front right wheel.
Engine RPM 2800.
Hydraulic oil at normal operating temperature.
Engage transmission lever to No. 1 position.
Push traction pedal to forward position. Front right wheel should rotate.
While watching flow and pressure gauges, slowly close flow control valve until 1000 PSI is obtained.
TESTER READINGS
Flow not less than 5 GPM at minimum 1000 PSI.
If flow is lower than 5 GPM or pressure of 1000 PSI cannot be obtained, there is internal valve bank leakage. Check:
1. Relief valve
2. No. 4 spool position
3. Disc seal between No. 3 and No. 4 valve bank sections
TEST C: TRACTION MOTOR EFFICIENCY
PROCEDURE
Tester Flow Control Valve Open.
Disconnect hydraulic hoses (pressure and return) that lead to front left motor. Install caps to open ends of tubes and
hoses.
Block up the machine so traction wheels are off floor. If machine is equipped with 3WD, rear wheel needs to be
off floor as well.
Apply brake and engage park lock.
Engine RPM 2800.
Hydraulic oil at normal operating temperature.
Engage transmission lever to No. 1 position.
Push traction pedal to forward position.
TESTER READINGS
Flow not more than 1.5 GPM at a pressure of 1850 to 1950 PSI.
If flow is higher than 1.5 GPM, remove right wheel motor and repair as necessary.
If pressure is not in listed range, remove traction relief cartridge from valve bank and examine for contamination or
damage.
If needed, test left front wheel motor by placing tester in left side pressure hose and blocking flow to right motor.
