| Title | Part 21 Notification - Test Stand Deficiency |
| Event Description | The following is a summary of information obtained from Engine Systems, INC. (ESI) via fax:
On February 14, 2019, ESI determined that all new P/N H40084720 EMD fuel injectors they supplied are considered suspect. The endurance test stand utilized for new EMD fuel injectors was found to contain a deficiency that may damage injectors during the testing process. There is a potential for the actuating stem of the endurance test stand to strike the injector follower off center, creating side loading that results in inadvertent rubbing between the follower and body. The condition is exacerbated by a lack of continuous lubrication from the test stand. Over the 2-hour test duration, the running surface of the follower scores and metal particles are introduced into the top end of the injector. The migration of these particles through the injector could initiate a seizure. An improperly functioning fuel injector could affect the load carrying capability of the diesel engine and adversely affect the diesel's ability to perform its safety-related function. The licensees affected are Columbia, St. Lucie, Dresden, Fitzpatrick, Point Beach, Turkey Point, Quad Cities, and Grand Gulf.
