Inspect all 0R0906, 0R1756, 0R1758, 0R2921, 0R2922, 0R2923, 0R2924, 0R2925, 0R3051, and 0R3052 Remanufactured Unit Injectors with date codes between January 01, 1997 and April 30, 1997 from Parts Stock.
The date code can be located below the part name and above the part number on part number tag attached to the box. The date code is formatted as DDMMYYXXX (example; a box marked with a date code of 150195068 would indicate a part manufactured on January 15, 1995 at plant number 068).
If the injector is no longer in the original box, use the date code engraved on the top of the unit injector tappet. It is in the "NUMERAL KOD" format. The code consists of the month and the year.
Where the numbers for the months and years are coded as follows:
January 1997 ... NUDKFebruary 1997... NMDKMarch 1997 ... NEDKApril 1997 ... NRDKTo inspect the injectors, push the rack bar in against the trim adjustment screw (the fuel off position). On the flat "D" section of the rack bar extending out of the injector and beyond the rack teeth, inspect for a shinny grooved machine mark completely across the flat surface and parallel with the rack teeth. This mark is caused by the plunger gear contacting the flat of the rack bar If the mark is present, the injector should be returned to Caterpillar.
Service Claim Allowances
Submit one claim for all 0R0906, 0R1756, 0R1758, 0R2921, 0R2922, 0R2923, 0R2924, 0R2925, 0R3051, and 0R3052 Remanufactured Unit Injectors with date codes between January 01, 1997 and April 30, 1997 removed from Parts Stock.
