This test determines if the loader valve relief is properly
set or working correctly. The components involved in this
test are: gear pump, hydraulic lines, loader valve and
test port fitting. If the pressure can not be adjusted to
meet specification then the loader valve or relief valve
will need to be repaired or replaced. If the pressure
meets specification the loader valve is not the problem.
The lift or tilt cylinder could be at fault.
System flow test should be completed to assure proper
flow from the pump is obtained.
1. Cycle the hydraulic oil until warm.
2. Park the unit on level ground.
3. Set the park brake.
4. Cycle the loader valve to relieve any pressure from
the circuit.
Note: There is no hydraulic test port for the drive or
loader circuits. Test port fittings need to be
purchased at a local hydraulic supplier.
