The Importance of Worn Bucket Teeth Replacement


The type of bucket teeth that you select for your grader, excavator or loader can spur on or hinder your construction project. The trick to effective bucket teeth selection is to ensure that you match up the tooth with adapter, and the shank with machine and work.

One of the most important things to consider when shopping for wear resistant bucket teeth is the manufacturing or forming process used during fabrication. There are 3 types of manufacturing processes typically used in the forming of bucket teeth as follows:

Forged bucket teeth: these offer the most impact and wear resistance. They are also known to last 50% longer than fabricated bucket teeth. The forging process involves heat treating high-quality alloy steel to ensure maximum durability and longevity.

Fabricated bucket teeth: these bucket teeth are also made from alloy steel and are self sharpening. The units are hardened to ensure resistance to wear, tear and impacts.

Cast bucket teeth: these bucket teeth are typically strong, yet lightweight by design. They are manufactured from austempered ductile iron and heat treated for optimal resistance to wear, tear and impact. Like the fabricated range of bucket teeth, cast bucket teeth are self-sharpening.

The lifespan and use of each of the bucket teeth units on the market is determined by their shape. And there are 3 factors that play a role, including wear life, penetration, and impact. Bucket teeth available on the market have varying degrees of each of these factors.

Determining how firm the tooth will stay over time depends on how you mount the tooth to the adapter. The mounting of the tooth to the adapter will also determine how easy it is to remove when it’s time to replace it. There are various retention systems to choose from when trying to select the right bucket teeth for the job, such as horizontal flex pin, diagonal flex pin, crimp on, and vertical roll pin.

There could be various negative impacts resulting from letting your worn bucket teeth remain attached for too long. Using worn bucket teeth will only result in a reduction in your machine’s digging performance and the requirement for expensive repairs to be carried out on the edge of the bucket. Therefore, it is essential to ensure that your bucket teeth are replaced before the adapter is worn. Damage to the adapter will result in new bucket teeth not fitting, tooth breakage, and excess wear.

In a word, having a set of maintenance schedule in place for your construction equipment and machinery can ensure that you never experience worn bucket teeth or adapter damage.
