Disconnect negative flow control line (6) from connector (12) and install plug (E2) and seal (13) .
Install Tooling (E) between connector (12) and pressure tap (3).
Attach a 3447 kPa (500 psi) pressure sensor (A2) to pressure tap (E5) to monitor negative flow control pressure for the drive pump.
Remove 311-1362 Vacuum Cap and install the filler plug for the hydraulic tank.
Attach a 41,368 kPa (6,000 psi) pressure sensor to pressure tap (1) for delivery pressure of the drive pump.
Install multi-tool group (C) on the engine to monitor engine speed.Idler Pump

Note: Perform the test for the drive pump and the test for the idler 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
