Engine Bearing Failure Analysis Tools
As you know, every automotive engine part will eventually wear out. If every part always performed for the full length of its expected life, your job would be fairly simple – to replace parts that have worn. Unfortunately, we cannot always count on an engine part failing only because its normal lifespan is exceeded. Mechanics must not only be a “replacer of parts” but they must be capable of diagnosis to determine why a part failed prematurely. Below are two different tools available to help you identify engine bearing failures.

Engine Bearing Failure Analysis Guide
MAHLE Aftermarket has created a brochure explaining various engine bearing failures. The pages of this manual are organized, for your convenience, into four major subjects:
- 1. Appearance – an illustration and brief description of a bearing that has failed due to a specific cause.
- 2. Damaging Action – what actually damaged the bearing under the conditions which were present.
- 3. Possible Causes – a listing of those factors capable of creating the particular damaging action.
- 4. Corrective Action – the action that should be taken to correct the cause of failure.
We believe you will find this reference manual easy to read and use, and that it will be very helpful to you in properly determining the cause of premature bearing failure.
