The list above is for reference. It is crucial to verify the blade thickness (22mm) and hole spacing (80mm) on your machine.
The tooth is mounted using plow bolts with nuts. We recommend replacing the bolts with new ones every time teeth are changed. This tooth pairs with the Right Corner Tooth (42N-812-1230) and Central Teeth (42N-833-1390).
Working with loose teeth leads to ovalization of holes in the bucket blade. This can result in permanent damage to the bucket and require costly blade repair. Regularly check bolt tightness.
Corner teeth act as a replaceable cutting edge and side cutter. They facilitate penetration and protect the bucket's permanent structure.

Corner teeth are asymmetrical. The wider side (flange) should be on the outside of the bucket, protecting its sidewall. The left tooth is mounted on the left side of the bucket (viewed from the cab).
It is the thickness of the bucket cutting edge onto which the tooth slides. If your blade is thicker (e.g., 25mm) or thinner, the tooth will not fit properly.
It is the distance between the centers of the mounting holes. For this tooth, it is 80mm.
