3G8354

The 3G8354 is a Caterpillar-compatible J350 series mounting adapter manufactured by AzuLong Wear Parts. This adapter provides the critical connection between the bucket lip and replaceable tooth points on mid-size excavators — the most common class on construction sites.

Adapter Profile — Application & Performance

Precision-engineered mounting adapter that provides a secure mechanical connection between the bucket lip and replaceable tooth points. Machined to tight tolerances for reliable fit and quick tooth changes in the field. The adapter absorbs the transition forces between the rigid bucket structure and the replaceable wear point.

Material & Durability

At 9 kg, this adapter is built for 15-25 ton class equipment. Manufactured from heat-treated alloy steel with HRC 48-52 hardness, this mid-range tooth is calibrated to match OEM weight and dimensional specifications. The controlled heat treatment achieves consistent hardness distribution from the tip — where abrasion resistance is critical — through to the base, where toughness prevents cracking under impact. Each tooth is inspected for dimensional accuracy before shipping.
