How to replace old bucket teeth by yourself?

Oct. 22, 2021

Determine the type of bucket teeth you have

Depending on the application, there are three types of bucket teeth commonly found on the market.

▷ Rock teeth: Rock teeth are usually suitable for excavation in iron ore, stone and other environments. They are made of heavy-duty wear-resistant steel, providing better digging performance and outstanding economic results.

▷ Tiger teeth: Tiger teeth are mainly used to penetrate rock layers with low hardness. Tiger teeth have a great impact force and are widely used in coal mining.

▷ Chisel teeth: Chisel teeth are bucket teeth used to excavate soil, sand and gravel in sandy terrain. Generally chisel teeth are used with buckets that have a large bucket mouth area and a large stacking surface, so the filling factor is high and the operating time is saved.

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 refers to the horizontal mounting of the pin. The side operation space is small, disassembly and installation is not very convenient, and special long pole tools are required for disassembly and installation. When digging, the side pin can withstand greater digging force, and is generally used for excavators of 20 tons or more. However, if the keeper is subjected to large reciprocating lateral force in use, it will easily wear out and cause the tooth pin to fall off.

▷ Top pin: Top pin type means that the pin is installed vertically with the excavator bucket teeth, with large operating space and easy removal, and the pin is smashed directly from above. When digging, the top pin will be subjected to the frontal squeezing pressure of the material, and if the digging force is large and the retainer does not meet the requirements, it is easy to cause the tooth pin to fall off, so this style is generally used for lower tonnage excavators.

 

Replacing worn bucket teeth

▷ Adjust the excavator bucket to the proper position for safety and stability (to prevent the bucket teeth from touching your legs or feet).

▷ Use a pin removal tool to remove worn teeth by tapping out the pointed pin from the side with the retainer.

Remove stains from the adapter with a wire brush or other cleaning tool. If the adapter is worn out, 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 it in with a sledgehammer, making sure that the pin is fully inserted.

▷ After completing the replacement of one tooth, you can successfully install all the teeth of your loader or excavator without professional help by repeating the above steps.
