How Do I Repair Broken Bucket Teeth

May 10, 2013

Excavator buckets are the most common type of excavator attachment, and can be used for a variety of tasks, ranging from digging and carrying dirt to breaking up rock or scooping up construction materials on job sites around the world. While the bucket is one of the most important parts on an excavator, it is also one of the most heavily used. From time to time, the bucket teeth on the machine will need to be repaired and replaced to keep the excavator running properly and make the operator money.

1、Determine which of the teeth on the bucket are damaged. Visually inspect them to see if the metal has sheared away due to force, or if the teeth in question are simply dulled or worn out from over-exposure and use. Worn out teeth can be removed via the bolts that hold them in place, while mangled or sheared teeth will need to be cut away with a cutting torch. In addition, some teeth are welded and bolted on, which means a cutting torch is mandatory to remove them.        

2、Unbolt the broken teeth and remove them. Use an impact wrench with an appropriate-sized socket to break the bolt free. Check for spot welds holding the tooth in place in addition to the bolt, and use the cutting torch to cut through the weld to remove the tooth, if necessary. Sharpen the tooth or replace it.        

3、Replace any broken teeth with new weld-on teeth or with bolt-on teeth or both, if applicable. Use the impact wrench to tighten the bolts holding the teeth in place on the lip of the bucket, and spot weld according to the manufacturer's instructions, depending on the type of teeth you purchase to replace the old ones.        

4、Repair sheared teeth that are still connected by welding them back together for light excavation projects, such as in soft dirt or clay. Replace the teeth if you are going to be working with rock or gravel areas that will put extensive pressure on the teeth.
