CATERPILLAR 227‑6189 Final Drive Travel Reduction Gearbox

If your CAT330D has started to lose pulling power or makes a worrying rumble when tracking, the final drive could be the reason. The Caterpillar 227-6189 final drive is the component that turns hydraulic force into smooth, reliable track movement—keeping your excavator moving steadily whether it’s climbing loose gravel banks, crossing muddy slopes, or working long hours in a quarry. The 227-6189 final drive sits inside a heavy alloy steel shell, built to take knocks without flinching. Inside, the gears are cut for a precise fit, so they run smooth even under a full load. A solid seal system keeps out the grit, dust, and water that usually spell trouble for bearings and gears.
