Replacement sprockets (drive sprockets) for Komatsu machines, each one listed against the Komatsu model it fits.
Models covered include the Komatsu PC05-6, PC10-6, PC14R-2, PC15R-8, PC18MR-2, PC27MR-2, PC30MR-1, PC35MR-2, PC40MRX-1, PC55MR-3, PC60-7 and PC75UU-1, with the full list of Komatsu models below.
Sprockets in this range use a heat treated steel profile with induction hardened teeth, cast in quality steel. A worn sprocket will shorten the life of a new track, so the two are usually replaced together.
