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 → ↗When OEMs cannot deliver, we measure, model, and manufacture replacement gearing in-house.
Read Capability → ↗Industrial buyers cannot afford to guess who is turning a wrench on their gearbox. Every technician who touches your equipment is certified, every rebuild is documented, and every job is backed by an unconditional warranty.
Certified for Timken bearing installation, tolerances, and failure analysis. Bearings are the number-one cause of gearbox failure — we install them right the first time.
Factory-certified for Falk gear drive rebuilds. Full access to OEM specifications, torque values, and lubrication standards. Your Falk unit is rebuilt the way Falk builds them.
Every rebuild ships with a 24-month unconditional warranty from installation date. No fine print, no exceptions. If our workmanship fails, we make it right.
Every gear we cut, rebuild, or manufacture is inspected to AGMA quality standards. Dimensional records, hardness, and geometry documented on every unit.
Ask any gearbox repair shop one question: "Who is actually doing the work?" A shocking number of "repair companies" are brokers — they take your gearbox, ship it out to whichever third-party shop is cheapest that week, and hope the certifications on the other end are good.
TOP NOTCH GEAR is different. Every repair, every rebuild, every custom gear, every dyno test — under our roof, by our certified technicians, on our equipment. Full control, full accountability, one warranty holder.
Come see for yourself. We host shop tours for prospective clients. Watch a rebuild in progress. Meet the technician who will touch your gearbox. If a repair shop won't let you walk the floor, you already have your answer.
Hot-shot freight and expedited LTL coordinated by our logistics team. We pick it up — anywhere in the 50 states.
Rebuild ships back to your dock at no additional freight cost. White-glove handling on critical units.
Live technician intake, rapid diagnostic assessment, honest quote. No sales team, no upsell.
Every phone call comes down to three words:
time, time, time.
When production is down, nothing else matters. Not price, not paperwork, not promises. Only how fast the line is running again. Every process at TOP NOTCH GEAR is built to compress that number.
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.
