Inspect the build date. The build date can be found on the shipping label on the box (Image 1).

Remove all new injectors within the date range D10M07Y17-D13M10Y17 from dealer parts stock.

Inspect all Reman injectors within the date range D10M07Y17-D13M10Y17. When checking the Reman injectors inspect the tappet.

If the tappet is lapped and has a dull gray appearance (Image 2), mark the box with a green dot under the label (Image 4) and mark the package to indicate that the injector has been inspected according to this program and return the injector to dealer parts stock.

If the tappet on the Reman injector has a shiny machined finish (Image 3) remove from stock.

If unable to differentiate between the tappets, then remove the injector from dealer parts stock.

For the injectors removed from dealer parts stock, refer to the Parts Disposition.

If there is a new or Reman injector in dealer parts stock that has a green dot under the label on the box (Image 4), inspection was completed at the parts depot and material is certified as acceptable to use.
