When the gearbox fails, the line stops. TOP NOTCH GEAR restores uptime for the largest factories, plants, mines, and refineries in North America — with 24/7 emergency response, documented rebuilds, and in-house gear manufacturing.
For the operations we serve, the deliverable is never a rebuilt gearbox. It's the production line back online, the kiln back at temperature, the mill back at full torque. Every capability we offer exists in service of one outcome.
Restore rated torque, rated speed, and rated life. Every rebuild ships to OEM specification or above — not patched, not repaired, restored.
Emergency Repair → ↗Documented root-cause failure analysis on every job. The failure mode is identified, corrected, and engineered out — so the next call isn't about the same gearbox.
Documented Rebuilds → ↗Obsolete, discontinued, OEM-gone? We reverse-engineer and manufacture replacement gearing in-house — so your legacy equipment keeps running for another generation.
Reverse Engineering → ↗For a steel mill, a cement plant, or a refinery, unplanned downtime is measured in hundreds of thousands of dollars per hour — sometimes more. A failed gearbox doesn't stop a machine. It stops a P&L.
TOP NOTCH GEAR is structured around that math. Live 24/7 intake, nationwide dispatch within hours, rush rebuilds in days. Every minute we shave off your return-to-service is real money kept on your balance sheet.
Every capability is in-house. We do not subcontract critical work. We do not wait on OEMs. We control quality, schedule, and turnaround from inbound freight to final QC.
Live intake. Rapid diagnostics. Rush teardown. Nationwide dispatch the moment you call.
Read Capability → ↗Parallel shaft, helical, bevel, worm, planetary, and custom gearboxes for plants and factories.
Read Capability → ↗Teardown, NDT, machining, gear cutting, reassembly, dyno test. OEM spec or better.
Read Capability → ↗Spur, helical, bevel, worm, and specialty gears. Hobbing, shaping, grinding, heat treat in-house.
Read Capability → ↗Falk, Dodge, Sumitomo, Hansen, Flender, Cone Drive, Nord — repaired, rebuilt, returned to service.
Read Capability → ↗When OEMs cannot deliver, we measure, model, and manufacture replacement gearing in-house.
Read Capability → ↗TOP NOTCH GEAR supports the largest, most demanding industrial environments in North America. The equipment, the duty cycle, the documentation standards — we understand the way you run.
We answer the phone when the line goes down. We rebuild faster than the OEM. And we document every decision like your reliability program depends on it.
A documented, accountable emergency repair process built around the cost of your downtime — and a logistics network that mobilizes in hours, not days.
Live 24/7 phone access to a technician. Unit details captured and dispatch coordinated within the call.
Hot-shot freight, expedited LTL, or technician travel coordinated by our logistics team — nationwide.
Full disassembly, NDT inspection, dimensional measurement, and documented failure analysis.
In-house machining, gear cutting, reassembly, dyno test, QC. Delivered back faster than OEM lead time.
If your question isn't covered, call our 24/7 hotline — a technician will answer immediately.
Call 1·800·XXX·XXXX →Yes. A live technician — not an answering service — picks up around the clock. When you're calling about a down gearbox, every minute matters and you need someone who can take technical information immediately.
Rush turnaround depends on size and condition, but our emergency rebuilds typically beat OEM lead times by weeks or months. Critical-path gearboxes have been rebuilt and dyno-tested in as little as 24–72 hours for catastrophic plant failures.
Any make, any model. Falk, Dodge, Sumitomo, Hansen, Flender, Cone Drive, Nord, Lufkin, Philadelphia Gear, Horsburgh & Scott, SEW Eurodrive, Rexnord, and custom OEM builds. If it transmits torque, we can repair or rebuild it.
Yes. We serve industrial clients in all 50 states and coordinate emergency freight, hot-shot delivery, and on-site technician dispatch nationwide.
Yes. Our gear manufacturing and reverse engineering capabilities mean obsolete or discontinued parts are not a problem. We measure, model, and manufacture replacement gears in-house.
Every repair includes documented root-cause failure analysis — written report with photographs, dimensional findings, metallurgical observations, and recommendations to prevent recurrence.
Live emergency intake 24 hours a day. We mobilize before you finish the call.
