Industrial Gearbox Repair — Built for Production-Critical Equipment
An industrial gearbox is rarely a standalone component — it sits in the middle of a production line, kiln drive, mill, conveyor, mixer, crusher, or pump system that your entire operation depends on. When it fails, you do not need a generalist repair shop. You need an industrial gearbox repair company that understands the application, the urgency, and the engineering required to return the unit to service better than new. That is what TOP NOTCH GEAR does every day.

Documented Failure Analysis on Every Repair
Every industrial gearbox we repair comes with a written failure analysis report. We document the root cause — whether it is lubrication, misalignment, overload, contamination, fatigue, or design — and provide recommendations to prevent recurrence. For large industrial clients, this documentation is critical for maintenance planning, capital budgeting, and reliability engineering.
Rush Turnaround for Production-Critical Repairs
We routinely turn around industrial gearbox repairs faster than OEMs can quote new replacements. Rush service is available on every repair, and our 24/7 emergency response means production downtime is minimized from the moment you call.
Frequently Asked Questions
What sizes of industrial gearboxes do you repair?+
From fractional horsepower reducers to multi-ton mill and kiln drives. There is no size limit — if it can be transported to our shop or supported on-site, we can repair it.

Yes. We service gearboxes from every OEM. The vast majority of our work is on units we did not build, including custom and obsolete designs.
Do you offer warranty on repaired industrial gearboxes?+
Yes. Every industrial gearbox repair comes with a written warranty on workmanship and parts. Specific terms depend on the scope of the rebuild.
Can you provide on-site industrial gearbox repair?+
Yes. For very large or installed equipment, we can dispatch field technicians for on-site repair, alignment, troubleshooting, and reinstallation.
How long does an industrial gearbox repair typically take?+
Standard turnaround is several weeks; rush turnaround is days. Critical-path emergency rebuilds have been completed in as little as 24-72 hours.
