Factory Price D10 Lug Pattern Excavator Idler Assy Front Idler

The D10 Idler Assy is a vital wear part in the undercarriage of Komatsu D10 series excavators, engineered to support the track chain, maintain proper track tension, and enable smooth, continuous movement of the tracks during excavation operations. As a core component of the "four-wheel-one-belt" undercarriage assembly (track links, rollers, idlers, and sprockets), the idler assy helps distribute the excavator’s weight evenly across the tracks, reducing stress on individual parts and preventing excessive wear.The product quality is excellent and it is worthy of being purchased by consumers.
