An essential bucket working component – a durable aftermarket tooth for the extremely popular CATERPILLAR J300 system. This is a standard dirt tooth profile, designed for general earthmoving, digging, and loading. The tooth is mounted on a weld-on adapter (e.g., 3G6304 / 9W1304) using a side pin and retainer. High-grade cast steel ensures high resistance to abrasion and impact. It is widely used on machines from various manufacturers (CAT, JCB, Komatsu, Case, etc.) that utilize the J300 system.

| Brand | Type / Series / Model |
|---|---|
| Universal | Any machine (Caterpillar, JCB, Bobcat, Takeuchi, John Deere, Case, Komatsu, Kubota, ESCO, Hensley, H&L) equipped with a J300 adapter system. |
The list above is for reference. It is crucial to verify the tooth system (J300) on your bucket's adapter.
When installing or removing teeth (knocking out pins), always wear safety glasses and use a proper hammer and punch. Metal fragments or retainers can fly off and cause serious eye injury.
The tooth is the main working part of the bucket that comes into direct contact with the ground. A worn tooth leads to decreased digging performance, increased resistance, and higher fuel consumption. A worn tooth also puts extra stress on the adapter, leading to its failure.

J300 is the size designation for a popular CATERPILLAR tooth system. It is one of the most common systems, used by many manufacturers (CAT, JCB, Komatsu) on backhoes and excavators in the approx. 15-25 ton operating weight class.
2. Will this tooth fit a J400 or J250 adapter?No. The CAT J-Series tooth systems are not interchangeable between sizes. A J300 tooth will only fit a J300 adapter and requires J300 hardware (9J2308/8E6259).
3. Why is it important to replace worn teeth?Working with worn, "rounded" teeth drastically increases digging resistance. This leads to higher fuel consumption, slower work, and places enormous stress on the adapters, cutting edge, and the arm's pins and bushings, accelerating their wear.
