Hydraulic America carries 268 final drive motors made to fit Caterpillar excavators, skid steers and compact track loaders. Every unit is new, shipped across the contiguous United States and Canada, and covered for up to two years, depending on the item. Most in-stock Cat final drive parts are dispatched the same day you order.
The catalogue runs from the 302 and 303 mini excavators through the 305, 307 and 308 compact machines to the 311, 312, 313 and 314 class, and includes the skid steer and compact track loader range. If your machine is a skid steer or a compact track loader, the model-by-model list on our CAT skid steer final drive motors page is the faster way in. Everything else is below: the full list of Cat final drives for sale, indexed by the number cast into the motor housing.
Caterpillar changed travel motor specifications mid-production more than once, so two machines wearing the same model badge can take different drives. Before you order, collect three things.
Clean the housing and read the stamped number, for example 442-5642 or 372-5830. That number is what this catalogue is built on and it removes all guesswork.
Serial breaks separate otherwise identical machines. This is the single most common cause of a drive arriving and not bolting up.
Bolt count, pitch circle and sprocket type vary across the range. Send the photo to our parts specialist team and we will check it against the manufacturer parts books before anything ships. We are in daily contact with our parent factory in South Korea, so specification questions get a real answer rather than a catalogue lookup.
Used Cat final drives from a dismantled machine are a gamble on someone else's maintenance history. You cannot see the condition of the planetary set, you do not know whether the drive ran on contaminated oil, and there is nothing to fall back on when it fails six weeks later. The units on this page are new, built by a manufacturer that has supplied hydraulic components to the heavy equipment industry for over forty years, with hardened gears and housings specified for high-impact work.
If you are weighing a rebuild against a replacement instead, the cost comparison is set out in rebuild or replace a final drive motor.
The wholesale final drive motors on this page come factory-direct, which keeps the supply chain short. There are no core charges and nothing to send back. Repair shops and rental fleets replacing several units at a time order the same way, one model list and one shipment. Send your machine list through the request a quote form and we will come back the same business day.
Two jobs decide whether the replacement lasts as long as it should. Flush the system if there was any metal in the old unit, because debris left in the lines will be pumped straight into the new motor. Our guide to flushing before a final drive replacement covers the procedure. Then check track tension with a gauge instead of judging it by eye, and pull the mounting bolts up to the published figures on our bolt torque settings page.
If the drive is still in the machine and you are not certain it is the problem, work through the symptoms of a failing final drive first. Cat owners diagnosing a specific fault on a track loader should also read the CAT 289D drive motor problem guide, which applies to most of the D-series family.
Orders leave our Ontario and New York warehouses the same day when the motor is in stock, and travel by UPS anywhere in the contiguous US and Canada. Nothing goes back afterwards, because there is no core to return. If the unit turns out to be the wrong one, ask us for an RGA number inside 30 days and send it back unused in its packaging. Cover runs up to two years, as stated on the item listing, under our warranty policy.
