Final Drive for Caterpillar 350

The Caterpillar 350 is a popular Cat platform with broad global parts demand. As a heavy excavator (around 50 t class), it is typically used for mass excavation, quarry and loading in rock. When its final drive wears — slow tracking, a leaking travel motor, noise from the track drive, or metal in the oil — a replacement travel motor and gearbox assembly is usually the fastest way back to work.

Why source this final drive through us

We help you source a matching final drive for the Caterpillar 350 from vetted China aftermarket and OEM-equivalent manufacturers, then confirm the exact unit against your tag before you commit. You get factory-direct pricing with technical checking on every order, not a blind cross-reference.

Confirm the exact fit before you order

Send the OEM number stamped on your travel motor or gearbox, your machine serial number, and a clear nameplate photo. We verify displacement, mounting bolt pattern, sprocket interface and speed ratio before quoting, so the unit that ships is the one that bolts on.

Same model name can mean a different unit

Different build years and regions of the Caterpillar 350 can use different final drives even within the same model name. Always confirm by serial number and nameplate rather than model name alone.

Buying questions

What is the lead time for a Caterpillar 350 final drive?
Lead time depends on the confirmed configuration and the supply route for your unit. Once we have matched the unit to your tag, the quote states packing dimensions, gross weight and the current lead time — these are confirmed per order rather than posted as blanket promises.
Do I need the nameplate part number to order?
It is the fastest way, but not required. Send a clear photo of the travel-motor nameplate together with the machine serial number and we identify the unit from the tag instead of guessing from the model name.
Is this an OEM or an aftermarket unit?
We source from vetted China aftermarket and OEM-equivalent manufacturers. Each quote states the supply type and country of origin for that specific unit, so you know exactly what you are buying.
How do you confirm the unit fits my machine?
We match the OEM number and machine serial, check the nameplate photo, and verify displacement, mounting bolt pattern, sprocket interface and speed ratio against the factory data sheet. The configuration is confirmed on paper before anything ships.
Do you ship worldwide?
Yes. We arrange EXW, FOB, CIF or air freight depending on destination and urgency. Shipping method, packing and terms are stated on your individual quote.
When will I receive my quote, and how long is it valid?
We reply after the configuration check is complete, and the quote states its own validity period. Complete nameplate details up front keep the turnaround short.
