An essential bucket working component – a high-quality aftermarket tooth for the popular CATERPILLAR J400 system. This is a standard dirt tooth profile, designed for general earthmoving, digging, and loading. The tooth is mounted on a weld-on adapter using a side pin and retainer. High-grade cast steel ensures high resistance to abrasion and impact. Fits machines from various manufacturers (CAT, JCB, Komatsu, etc.) using the J400 system.

| Brand | Type / Series / Model |
|---|---|
| CATERPILLAR (CAT) | Excavators: 231D, 320B, 320B L, 320B N, 320B S, 320C Wheel Loaders: 980G, 980G II, 980H, 980K |
| Other Brands | Any machine (JCB, Komatsu, Case, Bobcat, etc.) equipped with a J400 adapter system. |
The list above is for reference. It is crucial to verify the tooth system (J400) 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.

J400 is the size designation for a popular CATERPILLAR tooth system. It is a common system used by many manufacturers (CAT, JCB, Komatsu) on excavators and loaders in the approx. 30-40 ton operating weight class.
2. Will this tooth fit a J300 or J500 adapter?No. The CAT J-Series tooth systems are not interchangeable between sizes. A J400 tooth will only fit a J400 adapter and requires J400 hardware (7T3408/8E8409).
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.
