Doosan DX225LC-7 Sprocket / Drive Sprocket K1000682 – Heavy-Duty Undercarriage & Drivetrain Component

Description

The Doosan Sprocket (or Drive Sprocket), part number K1000682, is an indispensable component of your excavator’s undercarriage and drivetrain system. This toothed wheel is mounted on the final drive and is responsible for engaging with the track chain links, receiving power from the machine’s hydraulic travel motor and propelling the excavator forward or backward. Its precise interaction with the track chain is critical for efficient movement, optimal traction, and the overall longevity of your excavator’s track system.

This sprocket is confirmed to be compatible with a range of Doosan (and older Daewoo) excavators, including Doosan DX220, DX225LC, DX235LC, DH220-5, Solar S220-V, Solar S225-V, and Solar S230. Given the direct lineage and shared undercarriage architecture, the K1000682 sprocket is highly suitable for your Doosan DX225LC-7 model, ensuring a precise fit and reliable performance that meets or exceeds original equipment manufacturer specifications.

Typically constructed from high-strength alloy steel (such as 35SiMn or similar grades), this sprocket undergoes rigorous manufacturing processes including forging, casting, and advanced heat treatment. The teeth are meticulously machined and surface-hardened (commonly to HRC50-56 with a hardened depth of 4-10mm) to resist abrasive wear and maintain optimal engagement with the track chain, even under severe operating loads. The robust construction ensures it can withstand the continuous stress of power transmission and the harsh impacts encountered in typical excavation environments. A confirmed gross weight for a similar sprocket assembly is 55 kg, indicating a substantial and durable component designed for heavy-duty applications.

A worn, broken, or improperly fitting sprocket can lead to a cascade of problems, including reduced traction, track slippage, accelerated wear on track links and idlers, and potential damage to the final drive system. These issues compromise the machine’s stability, reduce operational efficiency, and can result in costly repairs and unexpected downtime. Replacing a failing sprocket with a high-quality, OEM-standard part like the K1000682 is crucial for maintaining the integrity of your excavator’s undercarriage and drivetrain, ensuring smooth and reliable operation, and safeguarding your significant investment in the machine.
