| Illustration 1 | g02139237 |
 |
|
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. |
|
|
Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact skin. |
|
|
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, type of control, and internal components of the pump. Refer to the Test Specifications and the tooling at the end of this document.

Pump Setup
Note: A sense pressure line from the pump should be connected to load sensing pressure port (7) when you use the Caterpillar Hydraulic Test Center. A sense pressure line from the pump should be connected to pressure port for load sensing (64) on the 4C-3582 Load Sensing Valve when using the Caterpillar Hydraulic Test Bench.
- Mount the pump with case drain port (49) facing up.
- Connect a 1 inch high pressure "XT6" hose from pump discharge port (58) to inlet port (68) on the 4C-3582 Load Sensing Valve.
- Connect a 1 inch high pressure "XT6" hose from outlet port (66) on the 4C-3582 Load Sensing Valve to the flow meter inlet on the test bench.
- Connect a 1 inch high-pressure hose from the flow meter outlet on the test bench back to the tank.
- Connect a 6D-7726 Hose Assembly to pressure port for load sensing (72). Connect the other end of 6D-7726 Hose Assembly to load sense pressure port (50b) on the pump.
Note: Do not use 1U-5754 Hose Assembly or 1U-5755 Hose Assembly for load sensing signal lines. The flow rate through these hoses will not compensate for the possible leakage through the control valve. Erratic readings will result.
- Connect 1U-5796 Pressure Differential Gauge Group (73) to high-pressure valve port (69) and low-pressure valve port (71) on the 4C-3582 Load Sensing Valve. The port marked "hi" (75) on the 1U-5796 Pressure Differential Gauge Group should be hooked up to the port marked "hi" (69) on the 4C-3582 Load Sensing Valve. The port marked "low" (74) on the 1U-5796 Pressure Differential Gauge Group should be hooked up to the port marked "low" (71) on the 4C-3582 Load Sensing Valve.
Note: The ports marked "low" (71) and "sense line" (72) on the 4C-3582 Load Sensing Valve are reading the same pressure.
- Fill the pump case with oil. Pour oil directly into a case drain port (49) until the case is full. Plug all case drain ports when case is full.
- Purge all air from the suction line. Loosen the suction hose at the pump until oil leaks from the connection. Tighten the suction hose.
- Do not rotate the pump in the wrong direction. The correct direction of rotation will be stated on the pump. The correct direction of rotation will also be in the Test Specifications. The direction of rotation is viewed from the input shaft end. Visually check the pump for proper rotation.
Test Procedure
Note: The steps in the Test Procedure correlate with the steps in the Test Specifications tables 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)
- Start rotating the pump according to the RPM in Step 1 of the Test Specifications. Listen for abnormal noise. Verify flow from the pump. Verify that all connections are tight. Check for leaks around shaft seals. Check for leaks around the control valve.
Run the pump for at least 5 minutes in order to raise the temperature of the oil and purge the system of air.
- Slowly increase the input RPM to the value in Step 2 of the Test Specifications. If the actual flow is less than the value given in Step 2 of the Test Specifications, the pump may not be mechanically feasible. The pump should be internally inspected.
- Slowly increase the input RPM to the value in Step 3 of the Test Specifications. The discharge flow is adjusted by using the 4C-3582 Load Sensing Valve. Bench circuitry will be used for flow limiting when you use a 1U-9400 Test Center.
Decrease the discharge flow by turning adjustment for discharge flow (67) according to the values in Step 3 of the Test Specifications. Adjust the discharge pressure according to the values in Step 3 of the Test Specifications. Adjust the screw for margin pressure (55) to the value in Step 3 of the Test Specifications. The margin pressure will be displayed on the 1U-5796 Pressure Differential Gauge (66).
Note: The margin pressure may change as discharge pressure changes. Adjust margin pressure in Step 3 only.
- Increase the discharge flow by turning adjustment for discharge flow (59) completely counterclockwise. Increase the pump discharge pressure to the value in Step 4 of the Test Specifications. After discharge pressure is increased, verify input torque according to Step 4 of the Test Specifications to ensure proper function of the torque control at the first point on the constant drive torque curve. If the input torque is not equivalent to the value given in Step 4 of the Test Specifications, the constant torque control will need to be adjusted.
Note: Adjusting the constant torque control (51) may be tedious. Only perform this adjustment if necessary. Marking the original settings and positions before making adjustments is recommended.
To adjust the constant torque control at this point, remove control adjustment cap (65), loosen outer spring locking nut (62), and turn outer spring adjustment nut (61). To increase input torque, turn outer spring adjustment nut (61) clockwise. To reduce input torque turn counterclockwise. Tighten outer spring locking nut (62) and reinstall the control shield (65).
- Increase the pump discharge pressure to the value in Step 5 of the Test Specifications. After discharge pressure is increased, verify input torque according to Step 5 of the Test Specifications to ensure proper function of the torque control at the second point on the constant drive torque curve. If the input torque is not equivalent to the value given in Step 5 of the Test Specifications, the constant torque control will need to be adjusted.
Note: Adjusting the constant torque control (51) may be tedious. Only perform this adjustment if necessary. Marking the original settings and positions before making adjustments is recommended.
To adjust the constant torque control at this point, remove control adjustment cap (65), loosen inner spring locking nut (63), and turn inner spring adjustment screw (64). To increase input torque, turn inner spring adjustment screw (64) clockwise. To reduce input torque turn counterclockwise. Tighten inner spring locking nut (63) and reinstall the control shield (65).
Note: If constant torque control (51) is adjusted, repeat Steps 4 and 5 to ensure accuracy at both points of the constant drive torque curve.
- Increase the pump discharge pressure to the value in Step 6 of the Test Specifications. If the high-pressure cut value is not equal to the value in Step 6 of the Test Specifications, turn adjustment screw for the high pressure cut (54) until the actual high pressure cut out value is equal to the value in Step 6 of the Test Specifications. The discharge flow should be zero when the high-pressure cut is reached.
