Fitment, width, tread, shipping, warranty — straight answers with links to Track Finder and money machine hubs.

  • Brand New

    New belts — not remills or retreads.

  • Drop Forged Steel Links

    Heat-treated guides for sprocket engagement.

  • Continuous Steel Cord

    Endless cord — no splice weak points.

  • 100% Virgin Rubber

    Contractor-grade compound for abrasion.

  • Precision Fitment

    OEM-spec width, pitch, and link count.

  • High-Traction, Low-Vibration

    Tread patterns matched to the jobsite.

Bottom rollers carry the machine. On a CAT 249D or 249D3 compact track loader, worn rollers flat-spot, cook bearings, and grind new rubber tracks into early scrap.

Replace rollers when you see

  • Flat spots on the roller OD (track thumps every revolution)
  • Side play or wobble with the machine locked out
  • Oil/grease leaks at the hub or seal
  • Chunked or missing flanges that no longer guide the belt
  • Uneven track wear matching a bad roller station

There is no honest universal hour number. Inspect when you change tracks — every time.

Why rollers and tracks are a pair

Install a new 320x86x49 or 400x86x49 belt on flat-spotted rollers and the new track inherits the damage pattern.
