Disc for Komatsu D155

The disc, part number 154-15-12715, serves as a functional component within the transmission or braking assemblies of heavy machinery. It is designed to either transmit torque or provide the necessary friction to manage the motion of the equipment, depending on its specific application within the drivetrain or brake system. In transmission assemblies, such components work alongside separators to engage or disengage engine power, while in braking systems, they provide the surface area required to create the force needed to stop the machine.

This part is compatible with Komatsu D155 bulldozers and HD785 rigid dump trucks. It is manufactured to meet the specific fitment requirements of these heavy-duty models, ensuring proper integration with existing transmission or brake hardware. Maintaining the integrity of these discs is necessary for the consistent operation of the drivetrain and the responsiveness of the braking system in both mining and construction environments.

In heavy machinery, discs are used to manage mechanical load and thermal energy generated during operation. They act as the primary interface for power transmission or deceleration, requiring precise alignment and surface contact to function correctly within the assembly.
