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 record 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.

Gauges provide an indication of the performance of the engine. Ensure that the gauges are in good working order. Determine the normal operating range by observing the gauges over time. Noticeable changes in gauge readings may indicate potential gauge or engine problems. Problems may be indicated by gauge readings that change even when the readings are within specifications. Determine and correct the cause of any significant change in the readings. Refer to the Troubleshooting Guide or contact your Cat dealer for assistance.
