REGULATOR AS 4177782 - Caterpillar

Inspect the annunciator panel for good condition. Perform a lamp test. All of the warning lamps should illuminate. If a warning lamp does not illuminate, replace the bulb immediately. If the alarm does not sound, investigate the problem and correct the problem.Check the condition of all of the gauges. If a gauge is broken, repair the gauge or replace the gauge immediately.Frequently monitor the following parameters during normal operation:
Fuel filter differential pressure
Inlet air restriction
Oil filter differential pressure Record the data in a log. Compare the new data to the data that was previously recorded. Comparing the new data to the recorded data will establish the normal gauge readings for the engine. A gauge reading that is abnormal may indicate a problem with operation or a problem with the gauge.Record the Performance of the Engine
Records of engine performance are an important element of a maintenance program. Record information about the engine operation on a daily basis. This will help to reveal the trends of the engine performance.The data on engine performance can help to predict problems with operation. Also, the data can provide your Caterpillar dealer with information that is useful for recommending optimum operation.Table 1 is offered for use as a log for engine performance. Make several copies of Table 1 for continued use. Retain the recorded information for reference.
