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.

Plumbing for double pump using the Tee Assembly (54) Discharge port |
Note: For double pump, both discharge ports must be connected together using XT-6 hoses with a 369-6833 Tee. The remaining outlet on the 369-6833 Tee will be the discharge port throughout the Pump Setup and the Test Procedure when testing a double pump. See Illustration 15 for Tee Assembly. See Illustration 16 for plumbing the double pump with the Tee Assembly. See Test Specifications for designation of double pump.
Note: Due to the limited spacing between the discharge ports on the double pump, a 1U-8303 Elbow must be used on one of the 9U-7440 Flange Adapters to allow clearance for the quick disconnects. The 1U-8303 Elbow requires a 360-3692 Plug and a 3J-1907 O-Ring to seal the 9/16-18 STOR port. A 7M-8485 O-Ring is required between the 9U-7440 Flange Adapter and the 8C-9032 Quick Disconnect Nipple.
- Connect a 1 inch high-pressure "XT6" hose from the pump discharge port (54) to inlet port (58) on the 4C-3582 Load Sensing Valve.
- Connect a 1 inch high-pressure "XT6" hose from outlet port (55) 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 the pressure port for load sensing (61). Connect the other end of 6D-7726 Hose Assembly to the pressure port for load sensing (51) 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 the 1U-5796 Pressure Differential Gauge Group (62) to the high-pressure valve port (57) and low-pressure valve port (60) on the 4C-3582 Load Sensing Valve. The port marked "hi" (64) on the 1U-5796 Pressure Differential Gauge Group should be hooked up to the port marked "hi" (57) on the 4C-3582 Load Sensing Valve. The port marked "low" (63) on the 1U-5796 Pressure Differential Gauge Group should be hooked up to the port marked "low" (60) on the 4C-3582 Load Sensing Valve.
Note: The ports marked "low" (60) and "sense line" (61) on the 4C-3582 Load Sensing Valve are reading the same pressure.
- Connect suction port (53) to the oil reservoir. Purge all air from the suction line. Loosen the suction hose at the pump until oil leaks from the connection. Tighten the suction hose.
- Fill the pump case with oil. Pour oil directly into case drain port (52) until the case is full.
- Direct a line from case drain port (52) to the test bench reservoir.
- 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
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)
Illustration 17 | g01172757 |
Load sensing and high-pressure cut characteristics (P) Discharge pressure (Q) Discharge flow |
- Start rotating the pump according to Step 1 of the Test Specifications. Listen for abnormal noise. Verify flow from the pump. Verify that all connections are not leaking. Check for leaks around shaft seals. Check for leaks around the control valve.
- Slowly increase the input RPM to the value in Step 2 of the Test Specifications. If the actual flow is less than the value in Step 2 of the Test Specifications, the pump may not be mechanically feasible. The pump is to be internally inspected.
- The discharge flow is adjusted by using the 4C-3582 Load Sensing Valve adjustment for discharge flow (56). Adjust the discharge flow 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 adjustment screw for margin pressure (49) to the value in Step 3 of the Test Specifications. The margin pressure will be displayed on 1U-5796 Pressure Differential Gauge (62).
Note: The margin pressure may change as discharge pressure changes. Adjust margin pressure at Step 3 of the Test Procedure within operating conditions only.
Return the pump to full flow by adjusting discharge flow (56).
- Adjust the pump discharge pressure to the value in Step 4 of the Test Specifications. Compare the actual case drain values with the values in Step 4 of the Test Specifications. This value is an indication of the efficiency. If the case drain is more than the value given in Step 4 of the Test Specifications, the pump may not be mechanically feasible. The pump is to be internally inspected.
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 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.
- Adjust the pump discharge pressure to the value in Step 5 of the Test Specifications. If the high-pressure cut is not within the test specifications, use the adjustment screw for the high pressure cut (50) until the actual high-pressure cut value is equal to the value in Step 5 of the Test Specifications. The discharge flow should be near zero when the high-pressure cut is reached.
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. Plug all of the ports.
