Doosan DX420 Track Adjuster / Tensioner Seal Kit 2274-6014AKT – OEM Quality Component

Description

The Doosan DX420 Track Adjuster / Tensioner Seal Kit, part number 2274-6014AKT, is a crucial set of components designed to maintain the integrity and performance of your excavator’s track tensioning system. While not the complete tensioner assembly, this kit provides the vital seals necessary for the hydraulic cylinder within the track adjuster. The track adjuster’s primary role is to maintain the correct tension of the track chain, which is essential for efficient machine movement, stability, and the longevity of all undercarriage components. The hydraulic cylinder, which is filled with grease or oil, allows for precise adjustment of the idler position to achieve optimal track tension.

This seal kit is typically manufactured from high-quality, durable materials such as PU, NBR, PTFE, and rubber, ensuring excellent resistance to high pressure, oil, abrasion, and various environmental conditions. These seals prevent the leakage of hydraulic grease or oil from the track adjuster cylinder, which is critical for the system to hold pressure and thus maintain track tension. Over time, seals can wear, crack, or become brittle, leading to a loss of pressure, inadequate track tension, premature wear on track links and rollers, and even the risk of track de-tracking.

Replacing worn seals with a genuine OEM-quality kit like the 2274-6014AKT is a cost-effective and essential maintenance procedure. It restores the hydraulic holding capability of the track adjuster, allowing it to properly absorb shocks from uneven terrain and maintain consistent track tension. This not only prevents costly damage to other undercarriage parts but also contributes to smoother machine operation, improved fuel efficiency by reducing friction, and significantly extends the overall service life of your track system. This kit is compatible with a range of heavy-duty Doosan excavators, including DX420, DX380, DX400, DX450, DX470, DX480, DX500, and DX520 series.
