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 an 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.
