DX180 DX180LC Final Drive for Excavator spare parts K1017674 Travel Motor with Reduction OEM

Product Overview

Picture a subdivision site: a Doosan DX180 backing up a truck with basement spoil, pivoting in tight rows between foundations. The crew is watching the clock, and the last thing anyone needs is one track to lose its bite halfway through a load. That pulling power comes from the travel motor and reduction box tucked inside each track frame — Doosan part K1017674. It takes high‑pressure oil from the main pump and trades speed for torque, spinning the sprocket slow enough to move an 18‑ton frame steadily over ruts and mud. Hours of reversing, curb climbs and loaded pulls leave their mark gradually: one track begins to trail the other on a straight line, the undercarriage shell runs warm to the touch after lunch, and a new whine creeps into the travel circuit. Most operators nurse it along until a track hesitates on a grade — but by then steel swarf has already worked its way through the motor. This OEM‑grade replacement arrives as one complete motor‑and‑reduction unit, matching the DX180 and the longer DX180LC undercarriage, so the old drive comes out in one lift and the new one drops straight in.

Core Advantages

1. One part number covers two undercarriage lengths
Whether the machine is the standard DX180 or the wider‑floated DX180LC, this drive shares the same mounting and output interface. Workshops running both variants keep one part on the shelf instead of two.

2. Smooth low‑speed control around foundations
Tight residential work demands fine track modulation. A lapped piston block and valve plate hold pressure without internal slip, so the operator can feather the machine between trenches without a jerky, grabbing track.

3. Gears cut to run quiet for years
Ground, hardened planetary teeth mesh with controlled backlash — no early‑life rattle, no harshening whine as hours pile up. The reducer stays civilised enough for neighbourhood work.

4. Sealed against mud‑season site conditions
Spring jobsites mean mud, puddles and pressure washer runoff. Fresh shaft and housing seals keep that slurry out of the lube and the motor, which is what separates a drive that lasts from one that fails before its first rebuild.

5. Drop‑in fit, no fabrication needed
Flange diameter, stud count and port positions all match the original. The service crew unbolts the old unit, bolts on the new one, bleeds the circuit, and the machine is tracking again the same afternoon.

Manufacturing & Quality Control

Each unit is assembled in a clean shop from traced, certified materials. Machined housings and ground gears are checked on CMM fixtures before build, and the finished drive spins on a hydraulic stand to map torque, pressure drop and noise across its speed range. Units that leak, bind or read outside spec come apart for rework rather than shipping. Before crating, the internals are fogged with preservation oil, the ports are plugged, and the assembly sits on a shock‑absorbing pallet for sea and road freight.

Frequently Asked Questions

Q1: How long does the swap take?
A: On the machine, a competent crew can exchange the drive in a single afternoon once the track frame is lifted — bolt‑out, bolt‑in, bleed and test.

Q2: Can this be fitted to either track side?
A: The design is symmetric for left and right on this platform. If your old drive carries a side‑specific tag, send it across and we will confirm.

Q3: What break‑in should the operator do?
A: Avoid full‑load reversing on grades for the first day. Let the tracks cycle under light load so the new gears and seals seat properly before digging in.

Q4: Do you supply only the gearbox or only the motor cartridge?
A: The listing is the complete assembly. If you are repairing rather than replacing, ask about internals — we can usually supply pistons, plates and gear sets separately.
