CENTER WELD-ON TOOTH ADAPTER (CAT J400) SUITABLE FOR CATERPILLAR, JCB - 6I6404

Technical Specification and Compatibility

An essential base for bucket teeth – a high-quality center weld-on adapter, compatible with the popular CATERPILLAR J400 system. It is designed to be welded onto a (approx. 46.5 mm) thick cutting edge. Made from high-grade cast steel, it is resistant to cracking and impact, providing a durable and solid mount for J400 teeth. This is a critical structural component that transfers digging forces from the bucket to the tooth.

Part number: 6I6404
Alternative part numbers: 7T3404
System: CAT J400
Type: Center, Weld-on Adapter
Lip Thickness: approx. 46.5 mm

Application in machines

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, Kubota, John Deere, ESCO, Hensley, H&L) with a 1.75" (44.5mm) lip and J400 tooth system.

The list above is for reference. It is crucial to verify the tooth system (J400) and lip thickness (1.75" / 44.5 mm).

⚠️ Installation Warning

Adapter installation requires welding. Welding work on structural attachments should only be performed by a certified welder, following proper procedures (pre-heating, correct welding consumables) to prevent cracks and ensure the full strength of the joint.

Part's Role in the Machine and Failure Diagnostics

The adapter is the base that mounts the tooth to the bucket's cutting edge. It is a critical component that transfers the entire digging force from the bucket to the tooth. Damage or wear makes work impossible and leads to lost teeth.

  • › Excessive wear of the adapter "nose", causing new teeth to be loose and "rock".
  • › Cracks in the adapter body or on the welds connecting it to the bucket.
  • › Complete breakage or detachment of the adapter from the bucket.
  • › Damaged pin hole, making it impossible to properly secure the tooth.

🔧 Expert's Guide: Key Installation Tips

  1. Surface preparation: Before welding, the edges of the adapter and the bucket lip must be beveled and perfectly clean (no rust, paint, or grease).
  2. Pre-heating: Cast steel adapters must be pre-heated (typically to 150-250°C) before welding to avoid thermal shock and cracking.
  3. Correct consumables: Use electrodes or wire designed for welding high-strength cast steel, not standard structural steel.
  4. Post-weld inspection: After cooling, thoroughly inspect the weld for any cracks or porosity.

Frequently Asked Questions (FAQ)

1. What does "J400 System" mean?

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 a J300 tooth fit this adapter?

No. The CAT J-Series tooth systems are not interchangeable between sizes. This J400 adapter will only fit J400 teeth (e.g., 7T3402) and requires J400 hardware (7T3408/8E8409).

3. Why must I pre-heat the adapter before welding?

Adapters are made of cast steel with a high carbon content, which gives them hardness but makes them susceptible to cracking during welding. Pre-heating slows down the cooling process of the weld, reduces stress, and prevents the formation of brittle structures in the metal, which is crucial for the joint's durability.
