System Pressure and Flow Checks
1. Connect a suitable hydraulic test unit to the powerpack. The unit should comprise a high pressure owmeter 0-50l/min, a gauge 0-
200 bar (0-3000psi), a temperature gauge, and a load valve. Suggested unit available from UCC (UC4120).
2. Connect the test unit to the power pack with the load valve and the By-Pass lever in the by-pass position and start the power pack.
Allow the engine to warm up, set the by-pass lever to the ow position. Close the load valve completely and check that the
relief valve setting is correct. The hydraulic oil will tend to get quite hot during this operation and therefore the checking should be
carried out as quickly as possible and the load valve opened before excessive temperatures are reached.
3. Carefully close the load valve to raise the pressure to 100 Bar. Check that the ow rate is between 18 and 20 l/min (28 and 30 l/min
for Major 30-140). Adjust the engine speed to give the correct ow.
DO NOT EXCEED 3600 RPM (2900 RPM for Major 30-140)"on load" . If correct ow cannot be obtained within max engine
speed then the pump must be replaced
