Connect two tees (15) to the negative flow signal pressure port of rear pump (24). Install cap (27) to tee (15) .
Connect one end of test hose (18) to tee (15) .
Connect the other end of test hose (18) to pressure tap (14) of pilot oil manifold (19) .
Connect test hose (44) to tee (15) .
Connect 6000 kPa (870 psi) pressure gauge (20) to the other end of test hose (44) .Test
Note: Perform the test for the front pump and the test for the rear pump one at a time.
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.
To prevent personal injury and/or equipment damage from failed lines or components while the hydraulic test equipment is returned to the open flow position, slowly open the hydraulic test equipment valve while monitoring the pump flow.If pump flow does not increase as the valve is opened, shut the engine off and determine what is preventing the pump from upstroking.
Start the engine.
Place the machine controls at the following settings: Power Mode, engine speed dial "10" and AEC switch OFF. Refer to Testing And Adjusting, "Engine Performance Test" for engine rpm settings.
Increase the hydraulic oil temperature to 55° 5°C (131° 9°F).

Pilot oil manifold (14) Pressure tap (29) Pilot relief valve
Adjust pilot relief valve (29) on pilot oil manifold (19) until the pressure reading at pressure gauge (20) that is connected to tee (15) is 2350 kPa (340 psi).
Record the negative flow at 2350 kPa (340 psi) in Table 1.

Corrected flow     =     Measured flow x 2100 rpm    
Measured rpm Flow measurements must be done in pressure rise.
