STATOR 4325045 - Caterpillar

if the problem with the machine is still present. Use the 133-4742 Portable Tech Station with M300 Technician or the 123-6471 Portable Diagnostic Tool (PDT) in order to determine if these problems are in the electronic system. If there are active system diagnostics that are detected, follow the procedure for the problem. See Testing And Adjusting, "Troubleshooting Detected Faults". You can observe the status of 16 different inputs and outputs (parameters). Determine the parameters that are applicable to the machine's problem. Use a service tool in order to verify that the inputs and outputs are behaving properly. If any input or output is not correct, repair the affected components or replace the affected components or wiring. Perform tests for the operation of the machine. Follow the procedures that are described for Testing and Adjusting the hydraulic system for the machine that is being tested. Compare the results of the operational tests with the specifications in order to determine the extent of the problem. The overall performance of the machine will decrease if there are any problems in the circuits between the pilot pump or main pumps and the control valve. This type of problem in the hydraulic system is not detected by the self-diagnostic functions of the electronic control system, as described above. In order to detect such a problem, it is necessary to check the flow characteristics of the pumps, the main relief pressure, pilot pressure, etc.
