PROBLEM
All 20R-0476 Injector Assemblies in dealer parts stock need to be inspected for the date code. 20R-0476 Injector Assemblies that have a date code of D08M07Y15P47 need to be removed from dealer parts stock. These injector as may have a nozzle assembly marked 2645K015 which is not correct. (Image1 = Incorrect) The correct nozzle assembly should be marked 2645K016. (Image2 = Correct) These two nozzles are not interchangeable.
ACTION REQUIRED
Inspect the date code on all 20R-0476 Injector Assemblies in dealer parts stock. 20R-0476 Injector Assemblies that have a date code of D08M07Y15P47 need to be removed from dealer parts stock.
