PROBLEM
Certain Reman fuel injectors were labeled with the same "2755" trim code from January 9, 2017 through April 18, 2017. The injector serial numbers of suspect injectors are 1825569 through 1880788. The trim code may or may not be correct. Image 1 shows a suspect trim code.
Parts from part distribution centers have been inspected and the boxes have been marked with a large green dot to indicate the injector has been inspected, marked correctly, or the trim code is correct. Refer to Image 2.
ACTION REQUIRED
Inspect the following Reman injectors in dealer parts stock:

Inspect the date code on the box.
If the date code on the box is not January 9, 2017 through April 18, 2017, then mark the box as inspected per this program and place the part back in dealer parts stock.
If the date code on the box is January 9, 2017 through April 18, 2017, then inspect the injector trim code.
If the trim code is not "2755", then mark the box as inspected per this program and place the part back in dealer parts stock.
If the trim code is "2755", then inspect the injector serial number using the following inspection and rework the procedure:
Use the following web address and download the spreadsheet file:
https://cat.box.com/s/4fwh9nz0lwguh8vomifxj2rapqjc27e9
Use the downloaded file. Type in the injector serial number to check the trim code. The spreadsheet will return whether the trim code is OK to use, or rework and mark the injector with the correct trim code.
Note: Some injector serial numbers will show "2755" as the correct trim code.
If the trim code is correct (acceptable trim code), record the injector serial number, then mark the box as inspected per this program and place the part back in dealer parts stock.
If the trim code is not correct (rework), the injector must be relabeled. Use an engraving tool to cross out the original trim code and write the correct trim code as shown in Image 3. Record the injector serial number and the updated/corrected trim code, then mark the box as reworked per this program and place the part back in dealer parts stock.
