The CAT 289D is a multi-width application in TrackTECH's current governed fitment catalog. It should not be published as a one-size machine or automatically treated as identical to every 279/289 D-series model.
Current CAT 289D Governed Fitments
| Size | Status |
|---|---|
| 400x86B56 | cataloged, release-ready; configuration-specific |
| 450x86B56 | cataloged, release-ready; configuration-specific |
Both rows use 86 mm pitch, 56 links, and the governed B-guide family. Width is the variable.
Can You Switch Widths?
Do not assume a width change is appropriate simply because both dimensions appear in the governed catalog. Confirm the currently installed track and the machine configuration before changing between 400 mm and 450 mm.
289D vs 289D3
The 289D3 has a cataloged 450x86B56 primary fitment. The 289D has confirmed 400 mm and 450 mm rows that both require configuration-specific fitment. That difference is why TrackTECH keeps model-level fitment records rather than copying a family chart.
Tread and Maintenance
After machine configuration, choose from the tread patterns actually offered for that width. Inspect sprockets, rollers, idlers, alignment, and tension components before installation, and follow the CAT service specification for tension and wear limits.
Use the Rubber Track Finder if the molded track size is unreadable or you are considering a width change.

Quick Buying Answers
Which rubber track rides the smoothest? For a verified fitment that offers it, Multi-Bar is usually the first tread to compare when lower vibration and smoother travel matter most.
Which track lasts longest on pavement? On asphalt and other hard, relatively flat surfaces, Multi-Bar is a strong first choice because it spreads contact across more tread bars. For harsher abrasive work such as broken concrete, rock, or demolition debris, compare a heavier C-Block or Staggered Block pattern instead.
What is the best track for paving? Start with Multi-Bar when ride quality, steady contact, and hard-surface travel are priorities. Confirm that the exact pattern is available for your machine before ordering.
What is the most affordable track? Price depends on the exact width, pitch, link count, guide type, and tread. Once fitment is confirmed, compare the live compatible options rather than changing dimensions just to save money.
What about mud, snow, or soft ground? Zig-Zag is usually the better pattern to compare when cleanout and bite matter more than pavement manners.
