Information contained in this document is considered Caterpillar: Confidential Yellow.

This special instruction includes test procedures for piston pumps. This Special Instruction also provides specifications. The technician should have a good understanding of hydraulic piston pumps. The technician should be educated in the operation of the hydraulic test bench. The test benches in this document are available through the Caterpillar Dealer Service Tools. Gather all necessary tooling before you need to hook up the pump. Some of the required tooling appears in a table at the end of this document. There are many possible variations of tooling that could be used. Not every possible variation can be listed.

Safety

Illustration 1	g02139237

Show/hide table

Personal injury or death can result from improperly checking for a leak. Always use a board or cardboard when checking for a leak. Escaping air or fluid under pressure, even a pin-hole size leak, can penetrate body tissue causing serious injury, and possible death. If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury.

Show/hide table

Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact skin.

Show/hide table

Pump test pressures in this guideline may exceed the normal operating range of the hydraulic test hoses utilized when connecting the tested pump to the test bench. However, the order of magnitude of these pressures is significantly below the burst strength of the Caterpillar "XT6" product. High pressure oil can escape through improperly assembled hoses and fittings. High pressure oil can also escape through poorly maintained hoses and fittings. High pressure oil may also leak through hose that has become damaged over the life of the hose due to the pressure levels that occur during test bench operation. Personal injury or death can result from improper hose & fitting inspection or improper hose replacement procedures. Escaping fluid under pressure can penetrate body tissue causing serious injury, and possible death. Thoroughly inspect all testing hoses, fittings, and quick disconnects prior to any testing operation. Check the assembly date tag or hose assembly log date for a hose life indicator. Replace all Test Bench hoses at a minimum of every 2 years or earlier if the hose or fittings appear to be damaged.

Summary

This procedure is specific to the type of pump and the type of control. The test procedure should be used with the"Tooling"and the "Test Specifications" sections. Both sections are displayed toward the back of this document.

Pump Setup

1. Connect a one inch high-pressure "XT-6" rated hose from the pump discharge port (51) to the flow meter inlet on the test bench.

2. Connect a one inch high-pressure "XT-6" rated hose from the flow meter outlet on the test bench back to the tank.

3. Connect the oil supply suction hose to pump inlet port (53).

4. Purge all air from the suction line before rotating the pump. Loosen the suction hose at the pump until oil leaks from the connection. Tighten the suction fitting.

5. Fill the pump case with oil before rotating. Pour oil directly into a case drain port until the case is full.

6. Connect an in-line flow meter to the case drain port (49) or (52). Direct the oil from the in-line flow meter back to the tank.

7. Do not rotate the pump in the wrong direction. The correct direction of rotation will be stated on the pump. The direction of rotation is viewed from the input shaft end. Visually check for proper rotation of the test bench.

Test Procedure

Note: The steps in the procedure correlate with the steps under the test specifications according to your specific part number.

The contamination level of the hydraulic oil in the test bench should be ISO 16/13 or better. 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)

Pump Characteristics (F) Discharge Flow (P) Discharge Pressure

Note: If the pump being tested has a control valve with two valves, always be sure the adjustment screw on the valve farthest from the pump is turned in completely. See Illustrations 7 and 8 for reference.

1. Start rotating the pump according to the RPM in Step 1 of the"Test Procedure". Listen for abnormal noise and verify flow from the pump. Be sure that all connections are secure and not leaking. Check for leaky shaft seals and control valve connections.

2. Slowly increase the input RPM to the value in Step 2 of the"Test Procedure". The adjustment screw for the maximum displacement (54) may need to be adjusted in order to achieve the correct discharge flow. The pump may not be feasible if the actual flow is less than the value in Step 2 of the"Test Procedure". The pump should be disassembled and inspected.

3. Increase the pump discharge pressure to the value in Step 3 of the"Test Procedure". Compare the actual case drain value with the case drain value in Step 3 of the"Test Procedure". This value is an indication of the pump efficiency. The pump may not be feasible if the case drain is more than the value in Step 3 of the"Test Procedure". The pump should be disassembled and inspected.

4. Increase the pump discharge pressure to the value in Step 4 of the"Test Procedure". Turn the adjustment screw for the high pressure cut (50) until the actual high-pressure cut value is equal to the value in Step 4 of the"Test Procedure". Pump discharge flow should be zero when the high-pressure cut is reached.

Show/hide table

Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact skin.

Reduce RPM and all pressures to zero. Remove the component from the test bench. Drain the oil from the pump. Cap and plug all ports.
