IntroductionDo not perform any procedure in this Special Instruction until you read this information and you understand this information. Refer to Special Instruction, SEHS7914 for any additional information.

This Special Instruction provides a procedure for the diagnosis of the engine related linear vibration problems for On-Highway Engines. The following Special Instruction will provide a method that will tell if the engine complies with Caterpillar's allowable vibration levels. Illustration 3 shows the complete troubleshooting procedure. Vibration complaints arise due to objectionable levels of vibration in the operator's compartment. Vibration problems are usually caused by one of the following:

Defects in the engine mounting due to misalignment or improper design

Defects in the cab mounting due to misalignment or improper design

Misalignment or equipment on the engine is not balanced.

Chassis resonance with orders of vibration in the engine that are standard

The above defects contribute to vibrations that may appear to the operator to be caused entirely by the engine. The troubleshooting procedure for the engine vibration that follows has been designed to diagnose the true source of the vibration with a minimum unnecessary expenditure of time and material.

A vibration meter that measures the amplitude of displacement and frequency is needed to perform the vibration analysis. 221-2370 Vibration Analyzer Group can be used to perform these tests. For more information, refer to Tool Operating Manual, NEHS0850.

Instructions for Completing the Engine Vibration QuestionnaireThe engine vibration questionnaire is a way to record the history of engine vibrations. The engine vibration questionnaire is a way to identify vibrations from nonengine components. A dynamic analysis is required when the vibration occurs while the vehicle is in motion. In most cases, the engine is not the cause of the vibration when this situation occurs. Instead, look for the components of the drive train that are out-of-balance or components that have been deformed due to the torque reaction.

Comments about suspected components are listed on the engine vibration questionnaire. If nonengine sources of vibration are discovered, consult the manufacturer of the chassis for assistance.
