Liebherr excavators — the R-series — are premium German-built machines trusted across Europe, the Middle East, Africa, and beyond for heavy construction, mining, and quarrying. Their final drives are engineered to the highest standards, and when replacement is needed, precision matching is everything.
This guide covers what to consider when replacing a Liebherr excavator final drive, and how BN Gears helps owners source a reliable aftermarket unit.
Liebherr's crawler excavator range spans compact models through large mining-class machines, including the well-known R 914, R 924, R 934, R 944, and R 950 generations, along with the newer G8-series (R 920, R 925, R 935, R 945, R 950) models. Final drive specifications differ between generations and machine classes — never order from the model name alone.
The full model designation and generation (e.g., R 924 vs R 924 G8)
The machine serial number
The OEM part number stamped on your existing final drive if available
Sprocket hole and frame hole counts on the current unit
Whether the unit is a travel gearbox with integrated motor housing or a separate assembly
Liebherr uses its own part numbering system, and dealer lead times can be long in some regions. An aftermarket manufacturer that can evaluate compatibility against these details — and develop new fits when needed — is the practical alternative.
BN Gears (Hongxiang Machinery) has manufactured travel and swing reducers since 2000, covering 600+ construction machinery models. If your Liebherr model is not yet in the standard catalog, the engineering team evaluates compatibility and can develop new fits on request.
