Safety
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 and the type of control. Refer to the test specifications and the tooling at the end of this document.

Note: Do not use 177-7860 Hose Assembly or 177-7861 Hose Assembly for load sensing signal. 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 (44) to high-pressure port (40) and low-pressure port (42) on the 4C-3582 Load Sensing Valve . The port marked "hi" (46) on the 1U-5796 Pressure Differential Gauge Group should be hooked up to the port marked "hi" (40) on the 4C-3582 Load Sensing Valve . The port marked "low" (45) on the 1U-5796 Pressure Differential Gauge Group should be hooked up to the port marked "low" (42) on the 4C-3582 Load Sensing Valve .
Note: The ports marked "low" (42) and "sense line" (43) on the 4C-3582 Load Sensing Valve are reading the same pressure.
Note: Verify that flow controls for discharge (1) and (38) are open.
Pump Pre-Test Set Up
Note: Mount the pump with the PTO flange downward in order to purge all the air from the pump.
- Connect signal pressure (8) from the test center to the pressure port for power shift (30). Refer to Illustration 2 and Illustration 4.
- Connect the remaining discharge port (33b) to the "F3" flow meter inlet (2) on the test bench.
Connect an 8T-0860 Gauge to each gauge port for discharge pressure (29a) and (29b). By using an 8T-7860 Fitting , connect an 8T-0860 Gauge to each pressure port for destroke (35a) and (35b) .
- Connect discharge port for the pilot pump (26) to an in-line flow meter in order to measure the discharge for the pilot pump.
- Connect suction port (34) to test bench oil supply (12) with the fabricated suction adapter. See Illustration 6.
- Purge all air from the suction lines before rotating the pump. Loosen the suction hose at the pump until oil leaks from the connection. Tighten the suction hose.
- Remove the plug from case drain port (32). Fill the pump case with oil before rotating. When the case is full, oil should exit case drain port (32). Reinstall the plug-in case drain port (32) .
- 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 correct direction of rotation.
Test Procedure
Illustration 10 | g01017523 |
Note: 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)
Note: For more accurate pressure readings, take pressure readings directly from gauge port for discharge pressure (29) and pressure port for destroke (35) .
- Start rotating the pump according to Step 1 of the test specifications. Listen for abnormal noise. Verify flow from discharge port for the pilot pump (26). Verify that all the connections are tight. Check for leaks around shaft seals. Check for leaks around the 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 RPM according to Step 2 of the test specifications.
If the discharge flow is not within specifications, adjustment is necessary. To decrease flow, loosen the locknut on adjustment screw for maximum angle (36). Turn adjustment screw for maximum angle (36) clockwise. To increase flow, loosen the locknut on adjustment screw for maximum angle (36). Turn adjustment screw for maximum angle (36) counterclockwise.
- Use the following steps to set the margin pressure of both pumps.
- Verify that flow controls for discharge (1) and (38) are wide open. Use adjustment knob for discharge pressure (41) in order to load pump discharge port (33a) slowly. Load discharge port (33a) to the load sensing pressure value in Step 3.a of the test specifications. Use adjustment knob for discharge flow (38) in order to restrict the discharge flow slowly. Restrict the flow to the value in Step 3.a of the test specifications. The discharge pressure and the margin pressure should now be equal to the values in Step 3.a of the test specifications.
If the margin pressure is not within specifications, adjust adjustment screw for margin pressure (27a). To increase margin pressure, loosen the locknut on adjustment screw for margin pressure (27a). Turn adjustment screw for margin pressure (27a) clockwise. To decrease margin pressure, loosen the locknut on adjustment screw for margin pressure (27a). Turn adjustment screw for margin pressure (27a) counterclockwise.
Note: Observe the gauge that is connected to pressure port for destroke (35). Destroke pressure will begin to rise just before the margin pressure setting is reached.
- Set margin pressure for the pump not connected to the 4C-3582 Load Sensing Valve . Slowly increase discharge pressure to discharge port (33b) to the value in Step 3.b of the test specifications. Use control for discharge flow (1) in order to restrict the discharge flow to the value in Step 3.b of the test specifications. Destroke pressure will begin to rise just before the margin pressure setting is reached.
If the margin pressure is not within specifications, adjust adjustment screw for margin pressure (27b). To increase margin pressure, loosen the locknut on adjustment screw for margin pressure (27b). Turn adjustment screw for margin pressure (27b) clockwise. To decrease margin pressure, loosen the locknut on adjustment screw for margin pressure (27b). Turn adjustment screw for margin pressure (27b) counterclockwise.
Adjust control for discharge flow (1) and load control for "F3" pump discharge pressure (24) after the margin pressure is set.
- Verify that flow controls for discharge (1) and (38) are wide open. Use adjustment knob for discharge pressure (41) in order to load pump discharge port (33a) slowly. Load discharge port (33a) to the load sensing pressure value in Step 3.a of the test specifications. Use adjustment knob for discharge flow (38) in order to restrict the discharge flow slowly. Restrict the flow to the value in Step 3.a of the test specifications. The discharge pressure and the margin pressure should now be equal to the values in Step 3.a of the test specifications.
- Verify that the adjustment screw for constant power is adjusted properly. Follow the following steps. Both pumps will be tested at the same time. Compare the flow rates at each step to the values in the test specifications. Refer to Illustration 10 for an example of a power curve.
Decrease input rpm and all pressures to zero. Connect a hose between gauge ports for discharge pressure (29) to pressure ports for load sensing (28). Connect a hose between the gauge ports in order to allow the pump to remain at full displacement at pressures higher than margin pressure.
- Slowly increase input RPM to the value in Step 4.a of the test specifications. Increase discharge pressure to both pumps to the value in Step 4.a of the test specifications. Observe the pressure gauge that is connected to pressure port for destroke (35). Destroke pressure will begin to rise when the pump starts to destroke. The pump is at the destroke point. The pump should now be under constant power control.
Equally cycle the load to both pumps. Cycle the load above the value in Step 4.a of the test specifications in order to verify the destroke point. As the pump discharge pressure increases, the flow rate for discharge should begin to drop. If either pump begins to destroke too soon, adjust screw for constant power (31a) or (31b). If either pump begins to destroke too late, adjust screw for constant power (31a) or (31b) .
To increase the flow rate, loosen the locknut on adjustment screw for constant power (31). Turn adjustment screw for constant power (31) clockwise until the flow rate matches the value in the test specifications. To decrease the flow rate, loosen the locknut on adjustment screw for constant power (31). Turn adjustment screw for constant power (31) counterclockwise until the flow rate matches the value in the test specifications.
- Use the test bench to load the pump to the value in Step 4.b of the test specifications. Observe the flow.
- Use the test bench to load the pump to the value in Step 4.c of the test specifications. Observe the flow.
Note: The pump control may need disassembled if the flow rates for discharge in Step 4.b and Step 4.c are not within specifications. Also, new springs may need installed.
Show/hide tablePump 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 during adjustment of the high pressure relief valve if recommended hose maintenance practices are not followed. Escaping fluid under pressure can penetrate body tissue causing serious injury, and possible death.
Adjustment of the high pressure cut or pressure override valve shall only be performed when the pump is operating at a zero discharge pressure condition. Continuation of the pump test procedure can be resumed when this high pressure adjustment is completed.
- Slowly increase input RPM to the value in Step 4.a of the test specifications. Increase discharge pressure to both pumps to the value in Step 4.a of the test specifications. Observe the pressure gauge that is connected to pressure port for destroke (35). Destroke pressure will begin to rise when the pump starts to destroke. The pump is at the destroke point. The pump should now be under constant power control.
Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact skin. |
Reduce input RPM and all pressures to zero. Remove the component from the bench. Drain the oil from the pump. Plug all ports.
