6Y0309HDU

The 6Y0309HDU is a Caterpillar-compatible ripper bucket tooth from the R300 series — a medium-duty CAT ripper tooth for mid-size bulldozers breaking compacted ground. Manufactured as a premium aftermarket replacement by AzuLong Wear Parts, it is designed for bulldozers performing ripping, land clearing, and site preparation.

Ripper Profile — Application & Performance

Built for extreme ripping operations, the ripper profile features a reinforced cross-section and hardened tip designed to break through frozen ground, compacted fill, asphalt, and rock formations. The geometry distributes impact forces across a wider area to prevent premature tip failure under heavy shock loads, while the elongated shape provides effective prying leverage.

Material & Durability

At 6.4 kg, this tooth is built for medium bulldozer 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.
