Our Industrial Gearbox Repair Process

Inspection & Disassembly
Sumitomo performs a visual inspection before disassembly. For each gearbox, Sumitomo disassembles it with extreme care, cataloging every part to prevent further damage.
Gearbox Evaluation
Reverse engineering allows us to verify the gear geometry and sizes of each gear and pinion requiring repair or replacement. We'll evaluate the unit for issues and broken parts.
Report Our Findings
Sumitomo provides the customer with a detailed quote based on findings and photographs after the evaluation.
The Repair Process Begins
Upon discussion of our inspection/findings and approval of your quote--our gearbox repair and rebuild process begins.
Gearbox Reassembly & Testing
Every gearbox is checked for tooth contact and backlash, and all shaft end play is recorded. We perform a no-load spin test at the top speed of the gearbox before shipping to ensure its correct operation.
Receive Your Unit Back
After rebuilding your gearbox, Sumitomo safely transports it back to your designated facility.
