Eagle Iron Works Gearbox Repair in Fontana

When a Eagle Iron Works gearbox starts making noise, running hot or shedding metal into its oil, the machine behind it is living on borrowed time. We rebuild Eagle Iron Works gearboxes working in aggregate washing plants — classifying tanks, sand screws and dewatering equipment drives at our Fontana shop at 14166 Whittram Ave — complete teardown, gear-by-gear measurement, bearing and seal renewal, and in-house gear manufacturing when a gear is worn, chipped or no longer supplied. The finished box is set to specification for preload and backlash and run-checked before it leaves, not simply put back together and hoped for.

How Eagle Iron Works gearboxes wear — and what we do about it

The Eagle Iron Works units that reach our bench most often show abrasive slurry ingress past output seals, screw-drive thrust wear, and corrosion-driven bearing failure in wet aggregate service. At teardown we record backlash, tooth contact patterns, bearing condition, shaft wear and housing bore condition before anything is cleaned, so the quote is built on the box you actually have rather than a catalogue guess. Worn gears can be rebuilt up in some cases or replaced with gears we cut ourselves — ring gears, helical, bevel, herringbone and worm work is all done in this shop — which keeps an older or discontinued Eagle Iron Works unit in service instead of scrapped. Housings are checked for bore wear and misalignment, seals and bearings are renewed as a set, shafts are repaired or manufactured where scoring demands it, and the rebuilt gearbox is assembled, set up and run-checked before release.

Frequently asked questions

Our Eagle Iron Works screw drive runs in slurry — can it be sealed better at rebuild?

Yes. At rebuild we renew seals as a set, check shaft seal surfaces and manufacture a new shaft or sleeve where grooving lets slurry in, then pressure-check the sealing before the drive goes back to the plant.

What are the warning signs a gearbox needs attention?

New whine or rumble, rising operating temperature, metal particles in the oil, backlash you can feel at the shaft, vibration under load and leaking seals. Caught early, most boxes need bearings, seals and setup rather than new gears.

Do you handle rush gearbox jobs?

Yes — emergency and rush repair runs 24 hours a day, every day of the year. Call (800) 821-3404 or (949) 400-2937.
