Issue
Rocky Mount Engine Plant (RMEP) issued Engine Serial Numbers (ESNs) assigned to previously
built engines. This has resulted in duplicate ESNs being issued.
Verification
Verify that the ESN is within the affected ESN range of 75000001 to 75004314 and is a mid-range
engine 9 liters or below and that the build year is 2022, by referencing the engine dataplate.
Resolution
The affected ESNs have been issued a new ESN.
New ESN and new engine dataplates for installation will be provided.
ESN 9970XXXX will replace ESN 7500XXXX. For example, ESN 75000001 is reissued as
ESN 99700001.
Reference Campaign C2643 for details and additional instructions.
Reason for Change
New ESNs and associated dataplates are issued to avoid potential difficulties in sourcing the
correct service parts and executing warranty claims.
Service Instructions
Campaign C2643 has been released to correct the ESNs. Refer to C2643 for details on how
to order new dataplates, replace and dispose of existing dataplates, and change the ESN
within the ECM.
The new ESN will be provided and new engine, engine control module (ECM), and secondary
(if applicable) dataplates will be sent.
Reference campaign C2643 for instructions to submit a warranty claim.
