Disconnect makeup line (10) from elbow (12) at the swing motor.
Assemble and install seals (D20), tee (D21), adapter (D19), seal (D4), and fitting (D5) to elbow (12) at the swing motor.
Install seal (11) and makeup line (10) to tee (D21).
Remove 311-1362 Vacuum Cap and install the filler plug for the hydraulic tank.
Connect portable hydraulic tester (D) and test hoses between coupling assembly at the drive pump and coupling assembly at the swing motor.
Attach a 41,368 kPa (6,000 psi) pressure sensor to pressure tap (1) for delivery pressure of the drive pump. Attach a 3445 kPa (500 psi) pressure sensor to pressure tap (3) for power shift pressure.
Install tooling (C) on the engine to monitor engine speed.Idler Pump
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.
Note: Perform the test for the drive pump and the test for the idler pump one at a time.

Position the machine on level ground.
Stop the engine.
Release pressure in the hydraulic system. Refer to Testing and Adjusting, "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. Refer to Illustration 5.
Disconnect delivery line (5) from the idler pump.
Install seal (9), half flanges (8), and blocking cover (D18) to the end of the delivery line with bolts (6) and washers (7).
Assemble and install seal (D17), adapter (D16), seals (D4), fitting (D12), seal (D11), plug (D10), and fitting (D5) on the idler pump by using half flanges (D15), bolts (D13), and washers (D14).
