Introduction
Sumitomo excavators — the SH series — are renowned for fuel efficiency and smooth operation, with a strong presence across Asia, the Middle East, and beyond. When a travel gearbox fails, a reliable aftermarket replacement is the fastest way back to production.
This guide covers Sumitomo final drive replacement across the SH series: the models BN Gears supports, how to confirm fitment, and why factory-direct supply matters.
Sumitomo Final Drives Supported by Model
BN Gears stocks and manufactures travel gearboxes and final drives for popular Sumitomo SH-series excavators:
Sumitomo SH models are generation-specific — an SH350A1 and an SH350A3 are not the same machine. Always confirm the full model designation (e.g., SH200A3 vs SH200-3), the part number stamped on your existing gearbox, and the sprocket and frame hole counts before ordering.
How to Order the Right Sumitomo Final Drive
Provide the full model name and generation (e.g., SH350A1)
Include the OEM part number from the existing gearbox if available
Confirm sprocket and frame hole counts
Specify painted or unpainted finish and delivery terms
Sumitomo Final Drive Maintenance Tips
Check gear oil level every 250 operating hours
Change gear oil every 1,000 hours (or per manufacturer spec)
Inspect floating seals during daily walk-around
Address grinding noise, track slippage, or oil leaks early to avoid complete gearbox failure
