Doosan DX300 Track Tensioner / Track Adjuster Assembly 200101-00005 – OEM Quality Undercarriage Component

Description

The Doosan DX300 Track Tensioner, part number 200101-00005, also widely known as a Track Adjuster or Recoil Spring Assembly, is a vital component within your heavy-duty excavator’s undercarriage system. Its primary function is to maintain the correct tension of the track chain, which is essential for efficient machine movement, stability, and the longevity of other undercarriage parts. This assembly typically includes a heavy-duty recoil spring, a hydraulic cylinder (piston), and a yoke that works in conjunction with the front idler. By absorbing shocks from uneven terrain and maintaining consistent track tension, it prevents premature wear on track links, rollers, sprockets, and the idler itself, directly contributing to extended track life and reduced operating costs.

Manufactured to stringent OEM specifications, this track tensioner assembly is constructed from high-strength steel and precision-machined components. The robust recoil spring is engineered to withstand significant compression and rebound cycles, effectively buffering impacts and maintaining tension. The hydraulic cylinder components are built for durability and sealed effectively to prevent grease loss, ensuring smooth adjustment and reliable shock absorption. Proper functioning of the track tensioner is critical; if the track is too loose, it can de-track or wear unevenly, and if it’s too tight, it can put excessive stress on all undercarriage components, leading to accelerated wear and potential damage. Common issues like broken springs or damaged seals can lead to a loss of tension, highlighting the need for a high-quality replacement.

Replacing a faulty track tensioner with a genuine OEM-quality part like the 200101-00005 is paramount for restoring your excavator’s optimal performance and minimizing costly downtime. A correctly functioning tensioner contributes to smoother machine operation, improved fuel efficiency by reducing friction, and significantly extends the service life of your entire track system. This assembly is an indispensable replacement for routine maintenance or when diagnosing issues related to track tension loss, abnormal undercarriage wear, or track de-tracking on your Doosan DX300, DX300LC, or DX300LCA excavator.
