Ensure optimal track tension and smooth operation of your Hitachi mini excavator with the YNF16736 Track Adjuster Seal Kit. This kit is a high-quality replacement for the original 9108186K part and is specially designed to fit the ZX17U-2 model.

Track adjusters are vital for maintaining the correct track tension on excavators, preventing derailment, reducing wear, and increasing track life. Over time, the seals in the tension cylinder degrade, leading to hydraulic fluid leaks and inconsistent tension. The YNF16736 seal kit contains all the necessary components to fully refurbish the tension cylinder and restore its factory performance.

This repair kit is manufactured from premium-grade materials to provide superior resistance to pressure, heat, and hydraulic fluids. It’s suitable for use in heavy-duty environments, including construction sites, demolition zones, and forestry operations.

Key Benefits

• Prevents track slack and misalignment
