To prevent personal injury or equipment damage from failure of the hydraulic test equipment or associated circuit components because of blocked pump flow, make sure that the test equipment valves are fully open before starting the engine.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat products.Dispose of all fluids according to local regulations and mandates.
Position the machine on level ground.
Stop the engine.
Release the pressure in the hydraulic system. Refer to Testing and Adjusting, "Hydraulic System Pressure - Release".
Attach 311-1362 Vacuum Cap onto the hydraulic tank. Attach an air supply hose onto the assembly. Apply 276 to 414 kPa (40 to 60 psi). This procedure will pull a vacuum on the hydraulic system.
Install the following tools in accordance with the flow meter tool layout and the circuit diagram. Refer to Illustration 1.
Assemble the basic flow meter and hoses.
Install a multitach on the engine.
Remove pilot line (2) from the connector at pilot pump (4).
Install seal (7) and plug (1) to the end of pilot line (2).
Install seal (7) and elbow (8) to the connector at pilot pump (4).
Install seal (9), coupling (12), seal (6) and nipple assembly (5) to elbow (8).

(22) Elbow
Disconnect makeup line (13) from elbow (22) at swing motor (16).
Assemble and install nipple (5), seal (6), coupling (12), seal (9), elbow (14), seal (9), swivel tee (15), and seal (9) to makeup line (13).
Install seal (9) and swivel tee (15) to elbow (22).
Remove 311-1362 Vacuum Cap and install the filler plug for the hydraulic tank.
Connect the portable hydraulic tester between nipple (5) at pilot pump (4) and nipple (5) at the swing motor.
Start the engine.
Place the machine controls at the following settings: engine speed dial "10" and AEC switch OFF. Refer to Testing and Adjusting, "Engine Performance - Test (Engine Speed)" for engine rpm settings.
Increase the hydraulic oil temperature to 55° 5°C (131° 9°F).
Turn valve (23) on the portable hydraulic tester clockwise until the pressure gauge on the portable hydraulic tester shows a reading of 4100 200 kPa (595 29 psi).
Record the pilot pump flow at 4100 200 kPa (595 29 psi) in Table 1.
