CAT Sprockets

Replacement sprockets (drive sprockets) for CAT machines, each one listed against the CAT model it fits.

Models covered include the CAT 239D, 239DR, 259B3, 279C, 279D, 289C2, 299C, 299D3, 301.8C, 304 CR, 305 CR and 308C CR, with the full list of CAT 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.

For the rest of the undercarriage, see CAT rubber tracks, CAT track rollers, CAT carrier rollers, CAT idlers, CAT track bolts & nuts and CAT rubber pads.
