KIT-GASKET 1457815 - Caterpillar

For basic troubleshooting of the engine, perform the following steps first in order to diagnose a malfunction.
Gather information about the complaint from the operator.
Verify that the complaint is not due to normal engine operation. Verify that the complaint is not due to error of the operator.
Perform a visual inspection. Inspect the following items:
Fuel supply
Oil level
Coolant level
Wiring
Electrical connectorsIf these inspections do not reveal any problems, identify the probable causes of the symptoms. The cause of a problem only provides an indication of the location of a possible problem. Conditions such as poor fuel quality or improperly adjusted components can cause some engine symptoms. All of the probable causes and recommended repairs cannot be provided. Additional work beyond the recommendation may be needed. A problem is not normally caused by a single part. Most problems involve the relationships of parts.Be sure to check the electrical connectors. This is specially true for problems that are intermittent. Narrow the probable cause. Consider the operator information, the conditions of operation, and the history of the engine. Service personnel may remember similar complaints which were corrected by a previous method of troubleshooting. However, a similar complaint can have a different cause.Operator Information
Obtain the following information from the operator:
The problem and the time of the occurrence
Determine the conditions for the occurrence. Refer to "Data Sheet".
Determine if there are any systems that were installed by the dealer or the customer that could cause the symptom.
Determine whether any other symptoms happened in addition to the problem.Note: If the problem only occurs under certain operating conditions (high idle, full load, engine operating temperature, etc), test the engine under those conditions.Other Symptoms
If other symptoms occurred in addition to the problem, determine whether the other symptoms are related to the problem. Determine whether the symptoms and the problem have a probable cause that is common.Report the Service Information
After you have successfully repaired the engine, it is important to provide good information about the repair. The following topics are recommended for your report:Complaint - Include a description of the customer's complaint in the report.Cause - Provide a specific description of the cause of the failure. Include the method that was used in order to diagnose the problem. For example, a visual inspection revealed abrasion of a wire in a harness. Be specific: testing of the engine produced power below specifications at 1800 rpm due to the loss of an ignition transformer.Repair - Explain your repair of the problem. For example, you may have installed a new wiring harness. You may have replaced the ignition transformer per instructions from the factory.Providing complete, accurate information will help Caterpillar provide better service to you and to the customer.Data Sheet
