Bobcat T770 Rubber Tracks — Complete Guide
The Bobcat T770 is one of the most recognized compact track loaders in the industry. With a 92-hp engine and Bobcat's proven vertical-lift geometry, the T770 handles construction, landscaping, and material handling with equal capability. Bobcat has been a market leader since inventing the first skid steer in the 1960s.
What size rubber track does the Bobcat T770 use?
The Bobcat T770 uses a 450x86x55 rubber track with a Block (B) guide. That's 450mm (18 inches) wide, 86mm pitch, 55 links. This size is shared with the T750, T740, Bobcat T650, T300, T320, and T250.
What tread patterns are available for the Bobcat T770?
- C-Block: OEM standard. Construction, demolition, hard surfaces.
- Zig-Zag: Mixed terrain, snow, all-season work.
- Straight Bar: Landscaping, turf, snow removal.
- X-Terrain: Extreme off-road, mud, forestry.
Bobcat T770 sprocket and undercarriage specs
The T770 uses Bobcat's 8-bolt 2-speed sprocket assembly:
- sprockets: OEM 7196807 (8-bolt, 2-speed) or 7165109 (6-bolt, single-speed on older units) — 17 teeth
- idlers (front): OEM 6732902 — sealed bearings, fits T140 through T770
- Rear idler: OEM 6732903
- rollers (bottom): OEM 6689371 — shared across most Bobcat T-series
Note: The T770 was available in both solid-mount and roller-suspension undercarriage configurations. Verify your serial number range before ordering undercarriage parts — front idler mounting differs between the two.
How long do Bobcat T770 tracks last?
The T770's mid-weight frame and 92-hp engine are moderate on track wear. Expect 1,500 to 2,000 hours under normal conditions. The T770 is slightly easier on tracks than heavier machines like the CAT 289D3 or Bobcat T870 due to lower operating weight.
Bobcat T770 vs T770-2 Pro — what changed for tracks?
