HOSE AS 3904576 - Caterpillar

Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the machine. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Dispose of all fluids according to local regulations and mandates.
Introduction
The following test will determine whether the pressure of the flywheel lubrication oil is within the specified limits. This oil is delivered to the torque divider from the priority valve. This oil is then distributed to the flywheel.Required Tools

(R) Pressure Tap
Attach tooling (A or B) to pressure tap (R) .Test Procedure
Start the engine. Warm the power train oil to a temperature of 84° 8°C (183° 14°F).
Make sure that the steering control lever is in the NEUTRAL position. Operate the engine at HIGH IDLE.
Check the pressure at tooling (A or B) . The pressure at tooling (A or B) should be 380 170 kPa (55 25 psi).
Make sure that the steering control lever is in the NEUTRAL position. Operate the engine at LOW IDLE.
Check the pressure at tooling (A or B) . The pressure at tooling (A or B) should be 205 105 kPa (30 15 psi).ReferenceSee Specifications, Systems Operation/Testing and Adjusting, "Pressure Charts" in this module for additional pressure values.Worksheet
