Komatsu Bulldozer Tooth D155
The 175-78-31230HD is an aftermarket replacement bulldozer tooth compatible with Komatsu D155 excavators — an aftermarket ripper point for Komatsu D155 large bulldozers performing heavy ripping. Manufactured by AzuLong Wear Parts to match OEM specifications, it provides reliable digging performance for Komatsu large bulldozers in heavy ripping and mining operations.
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.
At 16 kg, this tooth is built for large bulldozer class equipment. This heavy-duty tooth is forged from heat-treated alloy steel and finished to HRC 48-58, with the higher hardness range available for demanding rock and mining applications. The increased cross-section provides greater resistance to the bending loads that occur during heavy ripping and prying operations. The heat treatment process is tightly controlled to prevent internal stresses that could cause premature failure under shock loading.
Compatible with: Komatsu D155. 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.
