SK200‑8 Final Drive for Excavator spare parts YN15V00037F2 K3V112DTP‑YT6K OEM

Product Overview

The Kobelco SK200‑8 is a modern 20‑ton excavator working across infrastructure, road construction and bulk earthmoving, and the final drive under each track is the component that keeps it moving. The travel motor and planetary reducer referenced by part number YN15V00037F2 is what converts hydraulic flow into the slow, powerful rotation that pulls the machine across rough, rutted ground. On a 20‑ton machine that logs long hours, drive wear accumulates in stages: first the tracks stop quite matching speed, then the machine drifts on level ground, the drive housing warms faster than its opposite, and eventually one side hesitates rather than pulls. Running on past that point scores the piston group and reduction gears further, and contamination then spreads through the travel circuit. This OEM‑grade drive is built as one matched motor‑and‑reducer unit, so the worn assembly can be unbolted and the new one fitted in a single swap — the SK200‑8 moving again with minimum downtime.

Core Advantages

1. Motor internals that hold pressure for even track pull
The piston, cylinder block and valve plate are finished to tight tolerances, so hydraulic pressure does not leak away inside the unit. Both tracks then push in step — no wandering, no slow side, no hesitation the moment the bucket loads up.

2. Hardened reduction gears built for 20‑ton duty
The planetary gear set is case‑hardened and precision‑cut with controlled backlash. That keeps meshing smooth and quiet, spreads the drive torque across the teeth and slows wear from years of track push, ramp climbs and breakout force.

3. Sealed for long hours on mixed site conditions
Modern 20‑ton machines work through long shifts in quarry dust, mud and standing water. Fitted output‑shaft and housing seals keep grit out of the motor and reducer — the protection that decides whether a final drive lasts its service life.

4. One matched, tested assembly for a clean swap
Motor and reducer arrive pre‑assembled and bench‑checked, so the fitter removes the old drive and bolts on the new one without sourcing or mating separate components. On a machine that earns by the hour, that straightforward turnaround matters.

5. OEM‑spec build at a practical repair cost
An original Kobelco final drive exchange carries a premium price. This OEM‑grade unit matches the original fit and performance, giving workshops and fleet owners a dependable option with sample and bulk supply available.

Manufacturing & Quality Control

The OEM‑grade route follows controlled specifications: material certification, precision machining of housings and gears, case hardening of wear surfaces and clean assembly. Each completed drive runs on a test rig to verify output torque, internal leakage and running noise before release, and only passing units are packed. Full preservation coating, moisture sealing and shock‑absorbing export casing protect the assembly during transport.

Frequently Asked Questions

Q1: How do I confirm these references match my SK200‑8?
A: Check the tag on your existing drive against YN15V00037F2 and share your machine serial number. Build variants can differ, so we confirm the correct unit before dispatch.

Q2: Is this the complete motor and reducer?
A: Yes — the listing covers the full travel motor with planetary reduction as one assembly, ready to bolt on. Separate components can be checked on request.

Q3: What faults point to final drive wear?
A: Uneven track speed, drifting on flat ground, a hot or noisy track motor and tracks that fail to pull under load. Inspect before contamination spreads through the travel circuit.

Q4: What is the warranty position?
A: Manufacturing and material defects are covered. Damage from contaminated oil, debris in the motor, track obstruction, overload or incorrect installation is excluded; follow the Kobelco service manual for fitting and bleeding.
