Parts Compatible with the Bobcat T86 Compact Track Loader

The Bobcat T86 sits at the top of the R-Series compact track loader lineup, replacing the heavy-duty T770 and T870 in the M-Series. It uses the same redesigned R-Series cab as the T66 and T76, with the new front door glass, updated door seals, and revised control geometry that replaced the M-Series cab in 2021. Cab parts and most electrical components cross-fit across the R-Series, including the S66, S76, and S86 wheeled siblings.

Verify your serial number on the product page when ordering. Undercarriage components such as track tensioners, idlers, and drive sprockets are sized to the T86 and are not interchangeable with the smaller T66 or T76.
