If you excavator is down because a bucket tooth or some other ground engaging tool is worn down or broken then you'll need to find a replacement quick. Many companies now sell aftermarket bucket teeth online and can usually ship the same day. When your Caterpillar excavator, which is a piece of heavy machinary, is held up because your caterpillar bucket teeth have worn down or the bolt is broken, you have a serious problem.
Of course you can always contact your local Caterpillar sales rep but those parts are often very expensive and not always in stock. Finding aftermarket replacement bucket teeth is the best option as most of these companies do business online and are very customer service oriented. Many of these online resources for ground engaging tools carry not only cat bucket teeth but also have many other bucket replacement parts like Caterpillar guards, Caterpillar packer feet and Caterpillar sidecutters.
