CLAMP 3354180 - Caterpillar

Introduction
Use the following procedure to measure the case drain of the swing motor.
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.

Stop the engine.
Release the 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.

(1) Drain hose
(2) Elbow
(3) Swing motor
(4) Drain filter (located in the main pump compartment)
Install the following tools in accordance with the flow meter tool layout. Refer to Illustration 3.
Disconnect drain hose (1) from elbow (2).
Connect the flow meter assembly (D) between elbow (2) and drain hose (1).Note: Correct orientation of the flow meter is necessary. The oil flows from swing motor (3) to drain filter (4).
Remove 311-1362 Vacuum Cap.

Disconnect connector (6) from the solenoid valve for swing parking brake (5).Test Procedure
Start the engine.
Place the machine controls at the following settings: engine speed dial "10" and AEC switch OFF. 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 brake is activated.
Move the swing joystick fully for 1 minute. Measure the case drain oil. Refer to Table 1 or Table 2.
Stop the engine.
Connect connector (6) to the solenoid valve for the swing parking brake (5).
Repeat this test procedure three times to obtain three measurements of case drain oil. For each test procedure, swing the upper structure to a different position.
