Dodge gearboxes have been running industrial equipment since the early 1900s, and honestly, that's part of the problem when they fail — a lot of shops just don't stock parts for the older models anymore. We do. Whether it's a worn bearing, a cracked housing, or a full rebuild, we can usually get a Dodge gearbox back in service instead of you having to hunt down a replacement that might not even fit right.

If the repair vs. replace math is tight, we also offer flexible payment installment options, so downtime doesn't have to wreck your budget too.

The backbone of steel manufacturing, aviation components, and rail production?

Forging manipulators.

These precision machines work alongside hydraulic presses to shape metal under extreme heat and pressure. They grip, rotate, and position workpieces with incredible accuracy—often in environments exceeding 2000°F.

But here's what most people don't realize: the mechanical components inside these manipulators face brutal conditions. Constant thermal cycling, heavy loads, and continuous operation take their toll.

That's where reverse engineering becomes critical. When legacy equipment needs parts that are no longer manufactured, our team can recreate components to exact OEM specifications using precision boring, weld overlay, and custom brass sleeve manufacturing.

We don't just repair equipment—we keep entire production lines alive.

A vacuum pump doesn't actually "suck." It removes. 🌀

That distinction matters more than it sounds. A Duravac vacuum pump works by continuously pulling gas molecules out of a sealed space to create negative pressure — it's not pulling anything "in" so much as it's evacuating what's already there. Once wear creeps into the rotor, shaft, or impeller, that evacuation process loses efficiency fast, and most operators don't notice until output drops or the whole line slows down.

The fix isn't always a new pump. Once a Duravac unit is disassembled, cleaned, and measured, worn shafts, rotors, and impellers can often be rebuilt to spec — and when a part's too far gone, we manufacture a new one in-house instead of waiting on OEM lead times.

Free pickup and delivery. 24/7 emergency service if your line can't wait.

Why replace an entire Dyun gearbox when the problem might be one gear?

Grinding, overheating, or leaking doesn’t always mean it’s time for a new gearbox. A proper teardown can reveal what actually needs attention—and what doesn’t.

We inspect, measure, rebuild, and reverse-engineer Dyun gearboxes, manufacturing hard-to-find gears and shafts when needed instead of waiting on backordered parts. Every rebuilt unit goes through a 6-hour test cycle for heat, vibration, and leaks before leaving our shop.

Free pickup & delivery. 24/7 emergency turnaround. Plus, we offer flexible payment installment options to make a major repair easier on your budget.

Because sometimes, the smartest replacement is no replacement at all.

When a legacy Dover gearbox fails, plant managers usually face two frustrating options: waiting months for a backordered OEM replacement or paying top dollar for a new unit.

Rebuilding is almost always the smarter move—if it’s done right.

A proper Dover gearbox repair goes beyond swapping out seals and bearings. At National Gear Repair, units undergo a complete teardown and high-precision inspection. If worn helical gears, shafts, or worm drives are beyond saving, they're reverse engineered and re-manufactured in-house to original specs. That gets equipment back online in a fraction of the time, often at half the cost of buying new.

A Drive-All gearbox is built for hard work—but even tough equipment has its limits.

When you start noticing unusual noise, heat, vibration, or changes in performance, it may be time to take a closer look. Catching gearbox wear early can help prevent a small issue from turning into costly downtime.

National Gear Repair specializes in Drive-All gearbox repair and rebuilding, helping restore these workhorses and get them back in service.

Eagle Iron Works Gearbox Tip: Heat-Treated Helical Gears = Longevity

Eagle Iron Works gearboxes are built with heat-treated helical gears that allow triple reduction and oil bath lubrication for virtually maintenance-free operation. But even the best-engineered equipment eventually needs attention.

Regular inspections can catch small issues before they become costly failures. Monitor oil quality, listen for unusual sounds, and watch for temperature changes.

When repair time comes, National Gear Repair has you covered. Our Falk-certified technicians use thermal expansion methods—liquid nitrogen and induction heating—to ensure bearings and shafts lock perfectly into place. No shortcuts. Just precision.

We stock critical spare parts and can manufacture custom gears up to 20 feet in diameter. That's how we deliver the fastest lead times in the country without sacrificing quality.

Need Eagle Iron Works gearbox repair? We're here 24/7.

When a Diaphragm Pump Starts Acting Up…

A diaphragm pump may look simple, but there’s a lot happening inside.

The diaphragm moves back and forth to create suction and discharge, while check valves control the direction of flow. That simple cycle makes these pumps useful for handling everything from water and chemicals to slurries and other demanding fluids.

But constant cycling, abrasive materials, worn components, or gearbox problems can eventually take their toll. A pump that’s losing pressure, running rough, or simply not performing like it used to may need more than a quick fix.

At National Gear Repair, diaphragm pumps can be disassembled, cleaned, inspected, and measured to determine whether they can be rebuilt or require replacement components.

Sometimes the smartest solution isn’t replacing the whole pump—it’s finding out what actually failed.

Think your Egan gearbox is too far gone to save? Think again.

Grinding, leaking, or completely seized? A damaged gearbox doesn’t always mean you need a new one.

With Egan gearbox repair, worn gears and shafts can be rebuilt or even manufactured from scratch when OEM parts are no longer available. Through reverse engineering, everything is matched to the original specifications.

Before it leaves the shop, the rebuilt gearbox goes through a 6-hour test run to check for overheating, vibration, and leaks—backed by a 24-month warranty.

Repair it. Rebuild it. Keep your equipment running.

Eisenbeiss Gearbox: Built to Run. When It Needs Repair, Rebuild It Right.

Eisenbeiss gearboxes are designed for demanding industrial applications—but even heavy-duty equipment eventually needs maintenance or repair.

A proper Eisenbeiss gearbox repair starts with a complete teardown, cleaning, inspection, and measurement of gears and shafts. If components are beyond repair, replacement gears and shafts can be manufactured to specification. Every rebuilt unit is also put through a 6-hour test run to check for vibration, overheating, and leaks.

And when repair costs need to fit your budget, flexible payment installment options are available.
