Depending on the application, there are three common types of bucket teeth on the market.
Rock teeth: Rock teeth are typically used for excavation in environments such as iron ore and stone. They are made of heavy-duty wear-resistant steel and offer better digging performance and excellent economic efficiency.
Tiger teeth: Tiger teeth are mainly used to penetrate less hard rock formations. Tiger teeth have a high impact force and are widely used for coal mining.
Chisel teeth: Chisel teeth are bucket teeth used to excavate soil, sand and gravel in sandy areas. Chisel teeth are generally used in conjunction with buckets with a large bucket mouth area and a large stockpiling surface, resulting in a high loading factor and saving work time.
Determine your bucket tooth mounting method
Common mounting methods are the side pin mounting method and the top pin mounting method.
Side pin: The side pin type is a horizontally mounted pin. With little space for side operation, dismantling is less convenient and special long pole tools are required for dismantling. When digging, the side pins can withstand large digging forces and are generally used on excavators of 20 tonnes or more. However, if the keeper is subjected to large reciprocating lateral forces in use, it can easily wear out and cause the tooth pin to fall out.
Top pin: The top pin type means that the pin is installed vertically with the bucket teeth of the excavator, with a large operating space and easy removal, and the pin is smashed directly from above. When digging, the top pin is subjected to frontal squeezing pressure from the material. If the digging force is high and the retainer does not meet the requirements, it is easy to cause the tooth pin to fall out, so this style is generally used for small tonnage excavators.
Replacing worn bucket teeth
Adjust the excavator bucket to a safe and stable proper position (to prevent the bucket teeth from hitting the legs or feet).
Use a pin removal tool to remove worn teeth by tapping out the pointed pins from the side of the retainer.
Remove stains from the adapter with a wire brush or other cleaning tool. If the adapter is worn, replace it.
Place the new tooth and retainer in the original position of the adapter, insert the pin into the adapter and retainer and tap in with a sledgehammer, making sure that the pin is fully inserted.
Once you have completed the replacement of one tooth, repeat the above steps to successfully fit all the teeth of your loader or excavator without professional help.
