Disc for Komatsu D155

The disc, identified by part number 175-15-12715, serves as a fundamental mechanical component within the transmission or braking systems of heavy equipment. It functions by facilitating the transfer of power through friction or by dissipating energy to slow down or stop the machine. Proper installation and maintenance of this component are necessary to ensure the effective operation of the drivetrain and braking assemblies.

This part is designed for use in the Komatsu D155 bulldozer and the Komatsu HD785 rigid dump truck. It is engineered to meet the specific fitment requirements for these models, ensuring correct alignment and interaction with the surrounding transmission or brake hardware. Regular inspection of the disc for signs of wear or deformation is standard practice to maintain system integrity.

In heavy machinery, discs act as the primary interface for power engagement or kinetic energy dissipation. Within a transmission, they often function as friction plates that engage or disengage power flow. In braking systems, they provide the necessary surface area to convert kinetic energy into heat, thereby controlling the speed of the vehicle. Consistent contact and dimensional accuracy are required for these components to perform their intended function within the machine's power train or braking circuit.
