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.

That grinding noise from a Falk gearbox? Don't ignore it.

Grinding, unusual vibration, overheating, or oil leaks can point to problems with bearings, gears, lubrication, alignment, or gear mesh. Catching these signs early can help prevent a much bigger failure and unexpected downtime.

A proper Falk gearbox repair starts with a teardown and inspection—not just swapping out a damaged part. Gears, shafts, bearings, seals, clearances, backlash, and alignment all need to be checked before the unit goes back into service.

Regular oil checks, vibration monitoring, leak inspections, and keeping the gearbox properly aligned can also go a long way toward extending its service life.

Have you ever caught a gearbox problem early because of a noise or vibration? At National Gear Repair, we're Falk-certified and ready to help diagnose and repair your gearbox before small issues become big problems.
