Komatsu 20T-60-76710 Final Drive Motor（PC40-7）

On a PC40-7, the travel motor is the muscle that keeps the tracks moving, and when it’s worn, you feel it—sluggish travel, uneven turns, and lost time on the job. The 20T-60-76710 final drive motor brings that power back. Built with a thick steel case that shrugs off knocks and a gear system cut for smooth torque, it’s made to handle daily abuse on site. The seals are tough too—built to cope with heat, moisture, and gritty mud—so the gears inside stay clean and turning freely. It’s built to Komatsu specs, so it lines up right and bolts straight in.
