TrackTECH's current governed fitment catalog lists the CAT 289D3 with a merchant-confirmed primary rubber-track size of 450x86B56. That is the fitment fact that matters first; tread, price, and maintenance decisions come after the machine is matched to the correct track identity.
CAT 289D3 Track Size
| Model | Governed size | Status |
|---|---|---|
| CAT 289D3 | 450x86B56 | Merchant-confirmed primary, release-ready |
The size represents 450 mm width, 86 mm pitch, 56 links, and the governed B-guide family.
Do Not Assume Every 279/289 Model Uses the Same Configuration
Related CAT models can share dimensions, but model-family similarity is not enough to prove direct interchangeability. TrackTECH verifies each model as its own fitment record instead of copying one size across an entire D-series family.
Tread Pattern
Choose among the patterns currently offered in 450x86x56 after fitment is confirmed. C-Block, Zig-Zag, Multi-Bar, and other patterns can emphasize different combinations of traction, ride, cleanout, and surface impact. See the tread-pattern guide.
Undercarriage Check
Inspect sprockets, rollers, idlers, alignment, and the tensioning system before installation. Replace components based on measured wear and the CAT service criteria, not a generic every-other-track-change interval.
Track Tension
Use the CAT procedure and specification for the exact machine. Do not apply a universal 1-to-1.5-inch sag rule across CTLs.
Current Price and Availability
Rubber-track pricing and inventory change. Use the live CAT 289D3 collection or request a quote instead of relying on a static blog price.
If the machine identification or current track marking is unclear, use the Rubber Track Finder before ordering.
