SK230‑6 SK250‑6 Final Drive for Kobelco Excavator spare parts MAG‑1700VP‑3800 Travel Motor with Reduction OEM

Product Overview

The Kobelco SK230‑6 and SK250‑6 sit in the heavy mid‑size class — machines built for serious earthmoving, road construction and bulk excavation where the tracks carry real weight across rough, rutted ground. The MAG‑1700VP‑3800 travel motor with its integrated planetary reduction is the unit that delivers the sprocket torque to move these machines: a larger displacement motor than the 20‑ton class uses, matched to the heavier machine mass and harder working cycles. Because each final drive supports half the machine's weight while absorbing constant shock from track links, stones and uneven terrain, internal wear here is felt immediately. One track crawls slower, the machine drifts on level ground, the final drive housing runs hot, a deep whining note comes from the track motor, and eventually the track will not pull at all. Running a worn final drive only accelerates scoring of the piston group and pitting of the reduction gears. This OEM‑grade MAG‑1700VP‑3800 is built to the original specification — motor, reduction gearbox and output shaft matched as one assembly — so a worn unit can be exchanged directly and the machine gets moving again.

Core Advantages

1. Larger‑displacement motor matched to a heavier machine
The MAG‑1700VP displacement is sized for the SK230‑6 and SK250‑6's mass and duty cycle. That means the tracks hold their push on slopes and soft ground, without the laboured, slow travel that undersized replacements produce.

2. Hardened reduction gears for sustained torque output
The planetary gear set is case‑hardened to handle the repeated torque peaks of track push, ramp climbs and breakout forces. Hard gears share the load evenly and wear slowly, which is what keeps a final drive quiet and reliable for its full service life.

3. Sealed against heavy‑site contamination
Mid‑size excavators work in quarry dust, mud and standing water. Correct output‑shaft and housing sealing keeps grit out of the motor and reduction gearbox — the single most important protection against premature internal damage.

4. OEM‑grade build quality for a long‑service component
Final drives are rarely opened for routine service, so the internal build quality has to be right the first time. OEM‑grade tolerances on the piston group and gears mean the unit stays quiet, leak‑free and powerful through years of operation.

5. A complete assembly that drops straight in
Supplied as one motor‑and‑reduction unit, the final drive bolts into the original mounting position. No matching separate parts, no mid‑job surprises — the whole assembly exchanges, which is essential when a stationary machine is costing money every hour.

Manufacturing & Quality Control

The OEM‑grade route follows controlled specifications: material certification, precision gear and housing machining, heat treatment of wear surfaces and clean assembly. Each final drive is bench‑tested for output torque, leakage and running noise before release, and only passing units are packed. Full preservation treatment and shock‑absorbing export packing protect the assembly during long‑distance transport.

Frequently Asked Questions

Q1: How do I confirm this unit suits my machine?
A: Match the motor model on your existing final drive (MAG‑1700VP‑3800) and share your machine serial number. Build variants can differ between the SK230‑6 and SK250‑6, so we verify before dispatch.

Q2: Is this the complete travel motor and reduction gearbox?
A: Yes — the listing covers the full MAG‑1700VP‑3800 unit, motor and planetary reduction together, ready to install as one piece.

Q3: What symptoms point to final drive wear?
A: Uneven track speed, pulling to one side on level ground, a hot or noisy track motor and tracks that fail to pull under load. Inspect before contamination circulates through the travel circuit.

Q4: What is the warranty coverage?
A: Manufacturing and material defects are covered. Damage from contaminated oil, foreign objects in the travel circuit, track obstruction, overload operation or incorrect installation is excluded; please follow the Kobelco service manual for fitting and bleeding.
