Introduction
Injector height setting is extremely important during the engine assembly process. The recommended intervals that are specified in the Operation and Maintenance Manual must be followed.Problem
An issue has been identified with the correct injector height settings. Check the injector height. Bottoming of the fuel injector rocker arm may be caused by the injector height being to high or low. Bottoming of the fuel injector can create a crack at the nose of the fuel injector rocker arm through the first and second threads of the adjusting screw hole. Once the crack has started it can result in the breaking of the fuel injector rocker arm at the nose. Breaking of the fuel injector rocker arm will result in an immediate poor engine performance.Solution
Performing the recommended inspection of the fuel injector rocker arm at the specified intervals in the operation and maintenance manual is important. Inspect the height
