ACTION:

In order to qualify for repair under this field action, an engine:

• will be covered Regardless of coverage status, and
• must show an OPEN status for this field action on QuickServe®

After verifying that the engine meets the above requirements, perform the following actions:

NOTE: Data is needed from each ESN that is either campaigned or repaired in the field. Enter “data request” in to the search field in EDS or Guidanz and follow the solution to provide the data necessary.

• Remove and inspect the fuel pump tappets. Please refer to Fuel Pump Head Procedure 005-227 in Service Manual 4310641

– If no damage is found:

• Complete Installation of new fuel pump tappets. Please refer to Fuel Pump Head Procedure 005-227 in Service Manual 4310641.

NOTE: Warning! The tappet guide pins may rotate during the removal of the tappet. The tappet cannot be correctly installed if the tappet guide pin is out of position. Please refer to Attachment B for the proper orientation of the tappet guide pin.

NOTE: Use care when handling the roller tappet as the diamond-like coated tappet roller pin can fall out, resulting in damage to either the tappet roller or the pin. If the tappet roller pin does fall out during inspection, but the tappet roller and roller pin are not damaged, the roller pin can be reinserted.

• Mark the fuel pump head forging number with white paint, as illustrated in Attachment C, to signify completion of this field action.
