DX258 DX260 Final Drive for Excavator spare parts Travel Motor Assembly Aftermarket

Product Overview

The Doosan DX258 and DX260 are 25‑to‑26‑ton excavators built for general construction, quarry loading and large‑site grading — machines that balance dig depth with fuel economy on modern production crews. Under each track frame sits the travel motor assembly, the unit that takes high‑pressure oil from the main pump and turns it into the slow, torque‑rich pull moving the machine across uneven ground.

On a worked Doosan DX, the drive wears down in ways that crews often dismiss until they can no longer. One track lags on the ramp climb, the track shell warms faster than its opposite after a few cycles, and a low note builds through the floor under reversing. Most operators keep digging — but by then the piston block and valve plate have been lapping swarf into the oil. This aftermarket unit reproduces the original motor‑and‑reducer pairing as one sealed, bench‑run assembly, covering both the DX258 and DX260, so the worn drive lifts out whole and the new one bolts straight in.

Core Advantages

1. One assembly covers both DX258 and DX260
The travel motor platform is shared across these two Doosan models, so workshops running a mixed fleet keep one unit on the shelf rather than two separate parts.

2. A lapped piston group that holds pressure
The cylinder block, piston shoes and valve plate are finished to close clearance, so oil pressure does not bleed internally. Both tracks pull in step — no drift, no lazy side, no hesitation when the bucket loads up.

3. Hardened gears for modern production cycles
Doosan DX machines run long shifts on subdivisions and road jobs. Case‑hardened planetary teeth share the load across several surfaces, and controlled backlash keeps the reducer quiet.

4. Sealed for dust, mud and pressure washing
Whether the site is dusty topsoil or muddy clay, fresh shaft and housing seals keep grit out of the lube. That is the line between a drive that reaches its first rebuild and one that does not.

5. Aftermarket price for a high‑hour fleet
An OEM exchange drive carries a premium that is hard to justify on a worked DX. This unit restores full track mobility at a fraction of that cost, with sample and bulk supply available.

Manufacturing & Quality Control

Parts are machined to Doosan print, heat‑treated at wear points, and assembled in a clean shop. Each finished drive runs on a hydraulic stand while torque, leakage and noise are logged; units outside spec are reworked before packing. The internals are fogged with preservation oil, ports are plugged, and the assembly ships on shock‑absorbing dunnage.

Frequently Asked Questions

Q1: How do I confirm this fits my DX258 or DX260?
A: Send the machine serial number and a photo of the old drive's tag. Doosan build variants can differ between the two models, so we cross‑check before dispatch.

Q2: Is this the complete motor and reducer?
A: Yes — the listing is the full travel motor assembly with planetary reduction as one bolt‑on unit. If you need only internal parts, ask and we will check availability.

Q3: What symptoms mean the drive is wearing out?
A: Uneven track speed, pulling to one side, a hot or noisy track motor, and tracks that hesitate under load. Catch it before swarf spreads through the whole travel circuit.

Q4: Can I ship this by sea to African ports?
A: Yes — drives this size ship well by sea. Tell us the destination port and we will quote door‑to‑port or door‑to‑door, including any inland trucking needed.

Q5: What is the warranty position?
A: Materials and build defects are covered. Damage from dirty oil, debris in the motor, track obstruction, overload or incorrect fitting is excluded. Photograph any arrival damage before uncrating.
