NOTE: Necessary parts must be on hand before beginning this field action.
ACTION:
In order to qualify for repair under this field action, an engine:
1 will be covered Regardless of coverage status, and
2 must show OPEN on QuickServe® Online.
After verifying that the engine meets the above requirements, perform the following actions:
1 Remove and inspect the fuel pump tappets. Please refer to Fuel Pump Head Procedure 005-227 in Service
Manual 4310641.
NOTE: If the tappets or fuel pump cam are found damaged, please refer to TSB140019 for repair direction.

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

correctly installed if the tappet guide pin is out of position. Please refer to Attachment B for the proper
