175-78-31230

The 175-78-31230 is an aftermarket replacement bulldozer tooth compatible with Komatsu D85 excavators — an aftermarket replacement tooth for Komatsu D85 series bulldozers, workhorses of land clearing and earthmoving operations. Manufactured by AzuLong Wear Parts to match OEM specifications, it provides reliable digging performance for Komatsu bulldozers for dozing, ripping, and land clearing.

Bulldozer Profile — Application & Performance

Purpose-built for bulldozer blade applications including pushing, grading, slot dozing, and land clearing. The reinforced shank design withstands the lateral forces common in dozer operations, where teeth encounter loads from multiple angles as the blade pushes material forward and to the sides.

Material & Durability

At 13.5 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.

Compatible with: Komatsu D85, Komatsu D85EX, Komatsu D85PX. Always verify tooth-to-adapter fitment for your specific machine configuration before ordering. AzuLong's technical team can assist with compatibility confirmation — contact rocky@azulong.com or WhatsApp +86-13777046128.
