PROBLEM

The mounting location on the door group claw latch may leak water through the weld joint gap on certain 424B Backhoe Loaders. Water may leak through the gap and accumulate on the door frame. This can create a tumbling noise when the door is opened and closed. This can also cause water to leak through the frame weld gaps.
