The Doosan DX340 Excavator Undercarriage Chain Sprocket is a key component of the crawler undercarriage system. Working together with the track chain, the sprocket transfers driving force from the final drive to the track assembly, helping the excavator move smoothly across different working surfaces.

Xiamen Doozer supplies replacement sprockets for Doosan DX340 excavators, with options designed for undercarriage repair, routine maintenance and complete track system replacement. A properly matched sprocket helps maintain correct engagement with the track bushings and can help reduce irregular wear between the sprocket and track chain.

The 200108-00055 is listed by several undercarriage parts references as a sprocket rim for Doosan DX340LC, as well as related applications including S300LC-V, S340LC, DX300LCA and SOLAR340LC-V. Because undercarriage configurations can vary by machine version and serial number, the part number should be confirmed before ordering.

For heavy-duty excavator applications, sprocket manufacturing requires accurate tooth geometry, proper machining and controlled heat treatment. These factors affect the engagement between the sprocket and track chain and are important for maintaining reliable undercarriage performance. Supplier specifications for 200108-00055 commonly describe steel construction and heat-treated surfaces, although exact material and hardness can vary between manufacturers.

The DX340 undercarriage uses multiple components, including track chains, track shoes, bottom rollers, top rollers, sprockets and front idlers. A complete undercarriage replacement can therefore be coordinated according to the condition of the machine’s existing components.
