The information in the Service Bulletin will prevent the grain leakage from the front side of the grain pan on units that have a self-leveling cleaning shoe.

 

On some units, it is possible that  NEW HOLLAND incorrectly adjusted the grain pan seal on the front side in the factory. As a result, grain leakage occurs from the front side of the grain pan. The grains leak onto the ground, the traction beam, and the top of the transmission.
