Test Procedure
The hydraulic oil in the test bench should meet an ISO rating of 16/13. The oil in the test bench should be one of the following.
SAE 10W at 50 °C (122 °F) or
Mobil DTE-11 at 46 °C (115 °F)
Start rotating the motor according to Step 1 of the test specifications. Listen for abnormal noise. Verify that all connections are secure. Verify that all connections are not leaking. Check for leaks around shaft seals and control valves.Run the pump for at least 5 minutes in order to raise the temperature of the oil and purge the system of air.
Increase the input flow. Increase the back pressure on the output side of the motor according to Step 2 of the test specifications. Verify the RPM of the output shaft.
Apply pilot pressure to the pressure port for displacement control (51) according to Step 3 of the test specification. Verify the RPM of the output shaft. The motor should be at high speed.Test Specifications
