The information in this Service Bulletin advises you of the possibility that external noise can enter the cab through an air gap between the rubber door seal and the A-pillar of the cab frame. This concern affects both the left-hand door and the right-hand door of the cab.
To overcome this concern,NEW HOLLAND introduced an additional rubber seal for the cab frame. This additional rubber seal, in conjunction with the existing door seal, ensures an air tight seal between the door and the cab frame.
The additional rubber seal mounts on the rear edge of the A-pillar of the cab frame (A).
When the door (B) closes, the existing rubber door seal (C) should positively seal against the additional rubber seal strip (D).
The additional rubber seal is effective from the series 1965 onward.
If you find an air gap between the A-pillar of the cab frame and the door, NEW HOLLAND recommends you to install the additional rubber seal. See the below instructions.
