Main Relief Valve Pressure Test
Make reference to on first page of Testing And Adjusting.
The following tests and adjustments are performed with the machine engine operating. These tests are done away from the operator's station, so two people must be working. One person performs the tests and adjustments, and the other should be at the controls. This will help prevent accidental movement of the machine.
Travel/Pave Valve Manifold
(1) Travel and pave solenoids.1. Identify and disconnect electrical wires from pave and travel solenoids (1). This will allow the parking brake to stay applied during the test.
Main Relief Valves
(2) Forward main relief valve test port (3) Forward multi-function valve for right side pump. (4) Reverse main relief valve test port. (5) Reverse multi-function valve for right side pump.2. Assemble the 8T0861 Pressure Gauge with proper fittings from fittings group.3. Attach the pressure gauge to forward main relief valve test port (2) (right-side ground drive pump).4. Start and run the engine.5. The pressure setting for the forward main relief valve must be checked with machine in stall condition. Place the machine in the FORWARD, HIGH position. Increase engine speed to FAST. Put the propel lever in the fully FORWARD position.6. Observe the pressure gauge reading.
