SUPPORT AS-FRONT 1382530 - Caterpillar

General Information
When you are defining a problem in the power train system, the following procedure should be followed:
Prepare the machine for service.
Perform the visual inspection.
If the problem has not been identified, perform the operational checks that apply to your machine.
Perform any applicable calibration procedures that apply to your machine.
If the problem is not fully understood, perform the instrument tests.
When the problem is defined, go to Troubleshooting. Troubleshooting information can be found in this manual or in a separate Troubleshooting manual for this machine. The Troubleshooting lists the probable causes of a known problem. As there may be more than one cause for a problem, the Troubleshooting information may suggest specific inspections or instrument tests be done. The inspections and the tests help identify the most probable cause of a problem. The list cannot give all possible problems and corrections. During a diagnosis of the power train system, remember that correct oil flow and pressure are necessary for correct operation. The potential output of the power train oil pump increases with an increase in engine speed and decreases when engine speed is decreased. Oil pressure is caused by resistance to the flow of oil.Locations of the pressure taps and of the components are given in the Systems Operation portion of this manual. The pressure taps are also identified in each Testing and Adjusting procedure.Note: The monitoring system (if equipped) for your machine accesses many values that are useful in troubleshooting the power train system. When the situation is appropriate, use the monitoring system in order to find a pressure or determine a system problem.Warnings
Refer to the following warnings and notices for all inspections and tests of the power train.
Sudden movement of the machine or release of oil under pressure can cause injury to persons on or near the machine.To prevent possible injury, perform the procedure that follows before testing and adjusting the power train.
Hot hydraulic oil under high pressure can remain in the components of the hydraulic system or the power train system after the engine has been stopped. The uncontrolled release of the hydraulic oil can cause sudden machine movement and can also result in the following conditions:
Burns
The penetration of body tissue
Other personal injury
DeathIf hydraulic oil penetrates body tissue, the injury must be treated immediately by a doctor who is familiar with this type of injury. Use a board or a piece of cardboard to check for a hydraulic oil leak. Make sure that all of the attachments have been lowered to the ground and that all trapped pressure has been released from the hydraulic system and the power train system. Also, make sure that the hydraulic oil is cool before the removal of any components or lines. Remove the hydraulic oil filler cap only when the engine is stopped and the filler cap is cool enough to touch with your bare hand.
Escaping fluid under pressure, even a pinhole size leak, can penetrate body tissue, causing serious injury, and possible death. If fluid is injected into your skin,
