Specialized in large excavator walking drive parts. Three quality grades satisfy different budget demands. Strict QC system ensures long-term stable working performance. Sufficient stock supports global sea & air shipping. Supply professional installation guidance and after-sales technical service.

Q1: Are these part numbers mutually replaceable?

A: These codes are upgraded supersession numbers for the same final drive assembly and can be interchanged for maintenance replacement.

Q2: Can left and right drives be installed in reverse?

A: Partial PN correspond to left/right exclusive configuration, reversed installation will cause walking failure or insufficient traction.

Q3: Difference between rebuilt and genuine new final drive?

A: Rebuilt products replace all worn internal parts and reach OEM performance with cost advantages; genuine goods are original factory standard assemblies.

Q4: Delivery lead time?

A: Spot goods available, dispatched in 3–7 working days with worldwide logistics solutions supported.
