Gearbox Repair Service

Types of Industrial Gearboxes We Repair

KMS services every major gearbox configuration used in industrial settings — including units that other shops turn away.

Helical Gearboxes — The workhorse of manufacturing and material handling. We rebuild single, double, and triple-reduction helical gearboxes, restoring gear mesh geometry, replacing worn shafts and bearings, and resealing to OEM specifications.

Planetary Gearboxes — High-torque, compact designs used in conveyors, mixers, and heavy-duty drive systems. Planetary gearbox repair demands precision — we disassemble every planet gear and carrier, inspect to spec, and rebuild to exact tolerances.

Bevel and Bevel-Helical Gearboxes — Common in 90-degree drive applications including kilns, agitators, and cooling towers. KMS checks and corrects bevel gear contact patterns as part of every rebuild, ensuring quiet, efficient operation is restored.

Worm Gearboxes — Found in conveyors, gates, and positioning equipment. We replace worm gear sets and bronze worm wheels, and address the housing bore wear that often accompanies long-term worm gear service.

Parallel Shaft Gearboxes — Widely used in pumps, fans, and mixers, parallel shaft units are restored to full rated capacity — shaft replacement, bearing repacking, and seal replacement included.

Right-Angle and Custom Configurations — If it transmits torque, we can work on it. Contact us with your unit’s nameplate data and we’ll confirm serviceability.

Frequently Asked Questions — Industrial Gearbox Repair

How much does industrial gearbox repair cost? Gearbox repair cost depends on the unit size, damage severity, parts required, and whether custom gear cutting is needed. Simple seal and bearing replacements on smaller units may run a few hundred dollars; comprehensive rebuilds of large mill drives can run into five figures. KMS provides a detailed, itemized quote after inspection — before any work begins, so there are no surprises.

How long does gearbox repair take? Standard turnaround is typically 1–3 weeks depending on parts availability and repair scope. Rush and emergency service is available for critical equipment with tighter timelines. Contact us with your situation and we’ll give you an honest estimate.

Do you repair all brands of industrial gearboxes? Yes. KMS repairs Flender, Falk, SEW-Eurodrive, Dodge, Hansen, Rexnord, David Brown, Nord, Sumitomo, Boston Gear, and many other brands. If you don’t see your brand listed, call us — we almost certainly service it.

What’s the difference between a gearbox repair, rebuild, and replacement? A repair addresses specific failed components — a bearing, a seal, a single gear — while leaving serviceable components in place. A rebuild is a comprehensive teardown and restoration of all wear components, returning the unit to like-new condition. Replacement means sourcing a new or remanufactured gearbox. KMS helps you evaluate which option is right based on inspection findings, unit age, and your budget.

Is it better to repair or replace my industrial gearbox? In most cases, repair or rebuild is the economically smarter choice — especially for large, expensive gearboxes where a new unit would carry a long lead time and significant cost. The exception is when a gearbox has suffered catastrophic internal damage, is obsolete, or has exceeded its practical service life. Our inspection report gives you the data to make that call confidently.

Do you offer 24/7 emergency gearbox repair? Yes. KMS operates emergency intake around the clock. When a gearbox failure is shutting down your operation, call our emergency line and we’ll prioritize your repair immediately.

Do you provide a failure analysis report with every repair? Yes — always. Every repair includes a written failure analysis documenting the root cause, inspection measurements, and corrective actions taken. This is useful for maintenance records, insurance documentation, and preventing future failures.

How do I ship my gearbox to KMS safely? We’ll walk you through proper drain, seal, and preparation steps before shipping. For large or fragile units, we can coordinate custom crating and specialized freight carriers. Contact us before shipping and we’ll guide you through the process.

What warranty do you offer on gearbox repairs? KMS backs all repairs with a written warranty. Warranty terms are provided with your repair quote and included in your final documentation package.

Can you repair a gearbox that’s been out of service for years? Yes. Idle gearboxes often have corrosion, seal degradation, and lubricant breakdown — but these are recoverable conditions in most cases. We’ll inspect, assess, and advise you honestly on what’s involved and whether repair is economically justified.

Do you manufacture replacement gears in-house? Yes. KMS has in-house gear manufacturing capability. When replacement gears are unavailable off-the-shelf or require custom cutting to drawing, we can produce them — often faster and at lower cost than sourcing through a gearbox OEM.

Do you offer on-site gearbox repair? Our primary repair work is performed in our facility to ensure access to precision tooling, measuring equipment, and test capacity. Contact us to discuss on-site assessment or partial disassembly support if your situation requires it.
