Test Procedure (continued)
8. Start the engine and run it at low-idle speed. Check for hydraulic-fluid leaks
from the test connections and correct before continuing the test.
9. With the engine running, press the engine speed switch to full speed
(3,005
to 3,055 rpm)
position. Do not engage the cutting units. Use the InfoCenter
to check that the engine speed is correct.
10. Verify the pump flow at No Load as follows:
Record the tester pressure and flow readings at no load. Unrestricted pump
output should be approximately
32 L/minute (8.5 gallons/minute)
.
11. Verify the pump flow Under Load as follows:
CAUTION
Do not close the tester valve fully when performing this test. In this
test, the hydraulic tester is positioned before the manifold relief
valve.
Pump damage can occur if the fluid flow is fully restricted by fully
closing the tester flow control valve.
A. Monitor the tester pressure gauge carefully while you slowly close the
flow control valve until you get
10,340 kPa (1,500 psi)
.
B. Record the tester pressure and flow readings under load.
12. Press the engine speed switch to low speed
(1,175 to 1,225 rpm)
position
and shut off engine.
13. The under load test flow reading (step
B) should not drop more than 15%
when compared to the no load test flow reading (step
A). A difference in
flow of more than 15%, or the inability to achieve specified pressure may
indicate:
A. A restriction in the pump inlet line.
B. The gear pump being tested is worn and should be repaired or replaced;
refer to
Servicing the Gear Pump (page 6–170)
.
14. Release pressure from the hydraulic system; refer to
from the Hydraulic System (page 6–8)
.
15. Disconnect the tester from the machine and connect the hydraulic hose to
the gear pump fitting.
16. Start the engine, check for hydraulic-fluid leaks, repair any leaks as
necessary, and fill the hydraulic tank with the correct quantity of new hydraulic
fluid before returning the machine to service.
17. Lower and secure the operator seat.
