YNF16835 Seal Kit D31P-20 Track Adjuster Seal Kit Bulldozer Tension Cylinder Repair Kit

The YNF16835 Track Adjuster Seal Kit, compatible with the D31P-20 bulldozer, is engineered to restore sealing performance in the track tension cylinder. The track adjuster—also known as the recoil or tension cylinder—is essential for maintaining proper track tension. Worn seals can lead to hydraulic oil leakage, loss of track tension, misalignment, unstable travel, or derailment risks.

This seal kit includes high-pressure polyurethane seals, NBR O-rings, PTFE wear components, and dust seals that protect the adjuster from contamination and ensure smooth operation. Each component is manufactured to OEM specifications for precise fitment and long-term durability, even under heavy working conditions in construction, forestry, and mining.

Trusted by bulldozer maintenance providers, equipment rental fleets, and aftermarket distributors, the YNF16835 kit offers a reliable and cost-effective solution for restoring track adjuster performance and reducing machine downtime.
