PLATE-SPACER 6I4613 - 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
Engine oil level
Coolant level
Wiring
Electrical connectors
Check the diagnostic codes and event codes. Repair any active codes. If 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.Data Sheet
To help troubleshoot a gas engine, complete the information in Table 1. Be sure to include the units of measurement.
