Lufkin Gearbox Repair

Repair experience with Lufkin gearboxes

American Gearbox Repair repairs and rebuilds Lufkin gearboxes serving oil and gas production, marine propulsion and auxiliary drives, power transmission and general heavy industry. Our repair experience includes Lufkin parallel-shaft and right-angle reducers, high-speed gear units and the rugged enclosed drives built for continuous duty in harsh environments.

Please note: we are not an authorized dealer or authorized service center for Lufkin. We repair Lufkin equipment based on our repair experience, using careful inspection and rebuilding practices developed over years of working on industrial gearboxes.

Lufkin units often run for decades, so many of the boxes we see are older designs with worn gearing and obsolete parts. We inspect every unit fully before quoting, and where parts are no longer available we can often manufacture replacement gears and shafts in-house.

Common Lufkin gearbox problems we fix

• Gear tooth wear and scoring — long service life, heavy loads and marginal lubrication take their toll on tooth flanks
• Bearing failure — worn or spalled bearings on high-speed input shafts and slow-speed output shafts
• Oil leaks — failed lip seals, worn seal sleeves and gasket leaks at split-line housings
• Shaft wear — scored seal journals, worn bearing seats and damaged keyways
• Thrust and alignment damage — from coupling misalignment and axial loading in marine and pump drives
• Oil contamination damage — water or particulate ingress scoring gears and bearings
