The 159-0400 Sharp Bucket Teeth for Caterpillar Excavator is a J400 Series bucket tip designed for demanding excavation applications where strong material penetration is required. Cat identifies 159-0400 as a J400 Bucket Long Sharp Tip, featuring a sharp spike profile with a relatively small cross section. This design is intended to improve penetration when working in densely compacted materials.

As an important Ground Engaging Tool (GET), the bucket tooth protects the cutting edge of the excavator bucket while transferring digging force into the working material. The 159-0400 uses a long, sharp profile that can be useful for excavation conditions where penetration is more important than a wide cutting profile. Cat states that its J Series sharp long tips are factory sharpened and manufactured from cast steel designed to maintain hardness for wear life.

Xiamen Doozer supplies replacement 159-0400 bucket teeth for Caterpillar-style J400 bucket tooth systems. The aftermarket market also identifies 159-0400 as a Caterpillar J400-series tooth, with commonly referenced components including a 7T3408 pin and 8E8409 retainer. Fitment should be confirmed against the existing bucket adapter and machine configuration before ordering.

Application

The 159-0400 J400 sharp bucket tooth is particularly suited to excavation involving densely compacted materials, where a narrow and penetrating tooth profile can help concentrate digging force. It can be used for general excavation, earthmoving, trenching and other applications requiring effective bucket penetration.

For optimum performance, the tooth should be inspected together with the bucket adapter, pin and retainer. Excessive adapter wear or an incorrect tooth-to-adapter combination can affect installation and working performance.
