Test Procedure (continued)
Hydraulic System: Testing the Hydraulic System
Note: The pressure gauge reading should be approximately 27,600 kPa
(4,000 psi) as the relief valve lifts.
13. Release the traction lever to the N
flow-control valve, and shut off the engine. Record the test results.
Note: The forward relief valves for the 2 transmission pump circuits are
identical and thus you can interchange them. The reverse relief valves are
also identical. The forward relief valves, however, are different than the
reverse relief valves so do not interchange the forward and reverse relief
valves.
14. If the traction relief valve pressure is not met, remove and inspect the relief
valve from the transmission; refer to
Clean or replace the relief valve.
Note: The relief valves are not adjustable.
15. Release pressure from the hydraulic system; refer to
from the Hydraulic System (page
16. Disconnect the tester from the pump outlet fitting and hydraulic hose, and
connect the hose to the pump fitting.
