Traction Circuit Testing − Piston Pump/Hydrostat (P3) Flow and
Relief Pressure Test (continued)
B. Apply an additional load of
68.9 to 103.4 Bar (1000 to 1500 PSI)
by
slowly closing the flow meter. The flow meter pressure gauge should
read
117.2 to 144.8 Bar (1700 to 2100 PSI)
.
C. Record tester pressure and flow readings.
13. Verify traction relief valve operation as follows:
A. Return the traction pedal to neutral.
B. Fully close the flow meter flow control valve.
C. Depress the traction pedal slowly.
System pressure should reach
248 to 251 Bar (3600 to 3650 PSI)
before
the relief valve opens.
Note:
The relief valve setting is
241 Bar (3500 PSI)
. An additional
6.9
to 10.3 Bar (100 to 200 PSI)
is necessary to overcome system charge
pressure before the relief valve opens.
D. Record tester pressure reading.
E. Release traction pedal, open flow control valve fully, move throttle to
low speed and turn the engine off.
14. If relief pressure can not be met or is greater than specified, the traction relief
valve is faulty and should be replaced.
15. The Under Load test flow reading (
) should not drop more than 12% when
compared to the No Load test flow reading (
). A difference of more than
12% may indicate:
A. The hydrostat belt is worn and/or slipping.
B. The piston pump/hydrostat is worn and should be repaired or replaced.
16. Disconnect tester and reconnect hose to pump.
