Main features
The 17M‑30‑66151 Guide Wheel Bracket adopts one‑piece cast steel construction to deliver outstanding load‑bearing performance and high impact resistance for heavy‑duty operations. Manufactured to OEM dimensional specifications, it ensures precise fit‑up and seamless compatibility during field installation. Finished with heavy‑duty yellow coating for construction equipment, it delivers reliable anti‑corrosion and anti‑abrasion performance against mud, rock debris and harsh site conditions. Serving as the mounting base for the idler assembly, it works in coordination with the track tension system to stabilize track travel path, mitigate track wandering and minimize the risk of track derailment under severe working loads.
Applicable scenarios
Ideal for chassis overhaul and component replacement on Komatsu D275‑5 and D275‑6 bulldozers. Suited for heavy‑load site environments including open‑pit mining, earth‑moving projects and other abrasive operating conditions, as a direct replacement for worn or damaged original idler bracket assemblies.
