Troubleshooting
On the following pages there is a list of possible problems. To correct a problem, make reference to the CAUSE and CORRECTION.
If problems are encountered, they should be corrected promptly to maintain engine operation.
This list of problems, causes, and corrections, will only give an indication of where a possible problem can be, and what repairs may be needed.
Remember that a problem is not normally caused only by one part, but by the relation of one part with other parts.
This list can not give all possible problems and corrections. The serviceman must find the problem and its source, then make the necessary repairs.
Your Caterpillar dealer is equipped with the necessary tools and personnel to provide assistance when necessary.
