MOUNT 3580286 - Caterpillar

Machine Preparation
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.

Start the engine.
Place the machine controls at the following settings: engine speed dial "High Idle". Refer to Testing and Adjusting, "Engine Performance - Test (Engine Speed)" for engine rpm settings.
Place the hydraulic activation control lever in the UNLOCKED position.
Increase the hydraulic oil temperature to 55° 5°C (131° 9°F).
Slowly move the swing joystick and make sure that the swing parking brake is activated.
Move the swing joystick fully for 1 minute. Measure the case drain oil. Refer to Table 1.
Repeat this test procedure three times to obtain three measurements. For each test procedure, swing the upper structure to a different position.
