Takeuchi — the company that built the world's first compact excavator — remains one of the most trusted names in mini and compact excavators, especially in North America, Europe, and Japan. When a TB-series final drive fails, a precise replacement keeps downtime to a minimum.
This guide covers Takeuchi excavator final drive replacement across the TB series: the models that matter, how to verify fitment, and how BN Gears supports owners.
Takeuchi's crawler excavator range spans compact and mid-size classes, including well-known models such as the TB153 and TB290 (compact class), TB2150, TB2250, and TB2350 (mid-size class). Final drive specifications differ between classes and generations — never order from the model name alone.
The full model designation and generation (e.g., TB2250 vs TB2250-2)
The machine serial number
The OEM part number stamped on the travel motor or gearbox if available
Sprocket hole and frame hole counts on the current unit
Whether the travel motor is still serviceable — a gearbox-only replacement keeps costs down
Like most compact excavator manufacturers, Takeuchi builds its machines around proven hydraulic travel motor platforms. BN Gears supplies aftermarket travel motors and components across the most common motor brands used on compact machines:
BN Gears (Hongxiang Machinery) has manufactured travel and swing reducers since 2000, covering 600+ construction machinery models. If your Takeuchi model is not yet in the standard catalog, the engineering team evaluates compatibility and can develop new fits on request.
