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, "Caterpillar Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
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.

Repeat this test procedure three times in order to obtain three measurements. For each test procedure, swing the upper structure to a different position.The following values specify the maximum acceptable flow of case drain oil when the swing relief pressure is set at 31400 1000 kPa (4555 145 psi). New swing motor ... 30 L/min (7.9 US gpm) Rebuilt swing motor ... 35 L/min (9.2 US gpm)
