⚠️ Installation Warning

Welding an adapter is a critical operation. Proper pre-heating of the adapter and bucket lip must be observed to avoid weld cracks. When installing/removing teeth (knocking out pins 6254675), always wear safety glasses. Metal fragments can fly off and cause serious eye injury.

Part's Role in the Machine and Failure Diagnostics

The adapter is the foundation of the tooth system. It is permanently joined to the bucket and transfers all digging forces from the lip to the replaceable tooth. Its "nose" is the key locking component that must remain in perfect condition to prevent tooth loss.

  • › Cracked welds where the adapter joins the cutting edge.
  • › Worn or "rounded" adapter nose (causing the tooth to be loose).
  • › Ovalized or damaged pin hole for the 6254675 pin.
  • › Complete fracture of the adapter due to overload or impact.

🔧 Expert's Guide: Key Installation Tips

  1. Proper Welding: Adapters are cast steel and require correct welding procedures, including pre-heating, to prevent weld cracks.
  2. Protect the Adapter Nose: Never work with teeth that are worn down to the adapter. When the tooth is too short, all abrasive force is transferred to the adapter nose, destroying it irreversibly.
  3. Always Use New Retainers: Never reuse an old lock pin (6254675). It is a component that wears and loses its holding properties.

Frequently Asked Questions (FAQ)

1. What does "Bofors B-Lock" Size B1 mean?

Bofors is a popular tooth system, and "B-Lock" is a specific retention type. In this system, the tooth is slid onto the adapter and then locked with a vertical drive-through pin. "B1" is the size of the system - this adapter (31004 / 4046797) is exclusively for B1 teeth (e.g., 31102) and the B1 pin (6254675).

2. What is the difference between this adapter (4046797) and 4046819?

They are different sizes. This adapter (4046797) is Size B1. The 4046819 adapter (32004) is Size B2 (for 32101 teeth). They are not interchangeable.

3. Can I weld a CAT J300 tooth onto this?

No. This product is an adapter (a holder), which is designed to have a replaceable tooth *fitted* onto it. It is not designed to have another tooth welded to it. Furthermore, the Bofors B-Lock system is completely incompatible with the CAT J-Series.
