That grinding noise? It's not going to fix itself.

Titan gearboxes are built tough, but they're not maintenance-free. Ignoring early warning signs—unusual vibrations, temperature spikes, or oil contamination—can turn a simple bearing replacement into a complete catastrophic failure.

Our technicians use thermal expansion techniques and precision machining to restore Titan gearboxes to factory-new condition. We're talking .0001" tolerances and a 24-month warranty that doesn't start until you put the unit back into production.

Don't wait until your gearbox seizes. Preventive care saves you from costly emergency shutdowns.

Need a Titan gearbox inspection or rebuild? We offer flexible financing to keep your budget intact while your equipment gets back to work.

⚙️ Westech Gearbox Repair: From Disassembly to Like-New Performance

When your Westech gearbox arrives at our facility, it goes straight into our industrial parts washer for a thorough inspection. We measure every gear and shaft to determine what's repairable and what needs to be manufactured.

Once repairs are complete, we reset all original backlash, bearing floats, and preloads to OEM standards. Then comes the real test: a 6-hour run on our custom-built test bench to confirm zero leaks, proper temperatures, and smooth operation.

We stock critical spare parts and manufacture custom gearing in-house to keep your downtime minimal.

Rush service available. All work guaranteed for 24 months.

Every rebuild includes full teardown, in-house gear and shaft manufacturing to OEM hardness specs, and a 6-hour bench test. You'll save up to 60% compared to buying new.

⚙️ Your Winsmith gearbox just grenaded itself. Wednesday morning. Middle of a production run.

Your capital budget? Locked until January.

Here's the problem: waiting for budget approval costs more than the repair. Every hour that line sits idle, you're bleeding money.

So here's what we do differently: We start the repair NOW. You pay over time.

The repair itself? Full teardown, precision inspection, and if your gears or shafts are toast, we manufacture replacements in-house. Then we run a 6-hour bench test checking for heat, vibration, and leaks before it leaves our shop.

Free pickup. Free delivery. Free quotes.

Don't let budget cycles dictate your uptime.

🎈 ZF Gearbox Trivia Time!

Did you know ZF started as a gear supplier for Zeppelin airships? "Zahnradfabrik" literally translates to "gear factory" — and those early precision gears helped keep massive airships floating across Europe.

But when one of these German-engineered beasts needs repair, waiting for overseas parts isn't an option.

That's where we come in. National Gear Repair keeps critical ZF spare parts in stock stateside. Your gearbox gets the attention it needs the moment it arrives at our shop.

🔧 Full inspection and organic parts wash
🔧 In-house gear manufacturing (up to 20 feet in diameter!)
