Ultra Track Rear Idler – Restore Track Tension and Stability. Ultra Track rear idlers are designed to deliver reliable performance and a precise fit, matching OEM specifications for your equipment. Built with durable materials and sealed with high-quality double lip seals, these idlers keep out dirt and debris while retaining lubrication—ensuring long-lasting operation in rugged conditions. The rear idler plays a crucial role in maintaining proper track alignment and tension. When worn, it can reduce track tension and cause issues like rear de-tracking or premature wear on other components. If your tensioner is fully extended and slack remains, it’s often a sign the rear idler needs replacing. To extend the life of your undercarriage, we recommend inspecting all track components during routine maintenance and replacing worn parts together.

What Goes Into Every UltraTrack Track

Every UltraTrack rubber track is engineered with a multi-layer construction system designed for maximum service life under real jobsite conditions.

  • Continuous Steel Cord Belt — A single continuously wound steel cable runs the full length of the track, eliminating splice points that cause premature failure. This is the same belting method used in OEM tracks.
  • High-Tensile Steel Links — Drop-forged steel links engage cleanly with your machine's sprocket for smooth power transfer and reduced undercarriage wear.
  • 100% Virgin Rubber Compound — Acid-washed steel cords are bonded through multi-stage vulcanization. No reclaimed or recycled rubber. The result is a track body that resists delamination, cracking, and chunking even under sustained heavy loads.
  • UV and Ozone Stabilizers — Built-in antioxidants and antiozonants protect against sun and weather degradation, extending track life for machines that sit outdoors between jobs.

Undercarriage Care: Getting the Most Hours from Your UltraDrive Idlers

  • Check for Seal Leaks — Oil weeping at the hub means the seal is gone. A dry idler seizes, flat-spots, and starts cutting into the inner rail of the track.
  • Inspect the Flange and Tread Face — The idler flange is what keeps the track running straight. Once the flange is worn thin or cracked the track will wander and can derail under side load.
  • Verify the Tensioner Works — The idler carries the track adjuster. A seized grease cylinder or a tired recoil spring leaves the track permanently over- or under-tensioned no matter what you set.
  • Clean Around the Idler and Recoil — Packed material stops the recoil assembly absorbing shock loads, and that force goes straight into the idler and the track instead.
  • Check Alignment — An idler out of line with the sprocket wears one flange and one side of the rail. Uneven flange wear is the symptom; alignment is the cause.
