We’ve bought, sold, and rebuilt industrial gearboxes for years — we know the Cooling Tower Amarillo line, not just gears in general. That experience shows up in a correct diagnosis the first time.
Standard rebuilds ship in 5–14 business days with 24–72-hour emergency service — while a new unit can be 16–30 weeks out. We get your line running sooner.
You see the full picture before you commit — retail, used, surplus, repair, and a cash offer. Some shops take your unit in, tear it down, and only then hand you a quote you’re effectively forced to accept. We give you the numbers first.
Your gearbox is never held hostage. If repair isn’t the smart move, we’ll tell you — and we’ll buy the unit for cash so you walk away ahead instead of paying to get a paperweight back.
The Cooling Tower Amarillo B Series is a right-angle fan drive from Cooling Tower’s Amarillo line, rated 20–100 hp across ratios of varies by fan, and commonly found on cooling towers & ACC fans. Because Cooling Tower is the right-angle fan-drive family found on virtually every field-erected cooling tower in North America, these units turn up constantly for both rebuild and surplus buyback. When one fails the real question is never just "what does a repair cost" — it’s how our in-house repair cost and lead time compare to a standard shop, and how fast you can be running again. That side-by-side is exactly what the comparison above gives you, and it’s information most repair sites simply don’t publish.
On the Amarillo B Series, typical failure modes are bearing wear, shaft-seal leakage, and gear-tooth pitting from degraded or contaminated oil. Most units are fully rebuildable. A correct rebuild means full teardown, hot-tank cleaning, magnetic-particle inspection of all gearing for hidden cracks, verification of bearing-bore tolerances, new bearings, seals, shims and gaskets, reassembly to factory clearances, and a loaded run-test. Done right, that restores a fresh service life at a fraction of replacement — and our in-house cost and lead time come in below a standard shop, with the exact dollars and days shown in the comparison above, versus the 16–30 weeks a new Amarillo B Series can take to arrive.
Here’s the part worth being honest about: repair isn’t always the answer. If the housing is cracked or the gears are unavailable, a used, surplus, or reman Amarillo B Series may be cheaper and faster than rebuilding — and if that’s the case we’ll say so and buy your failed unit for cash rather than talk you into a repair that doesn’t pay. That two-way position is deliberate. A shop that only earns money when you repair has every reason to take your gearbox in, disassemble it, and hand you a quote you can no longer walk away from. We put every number in front of you first, and we don’t hold your equipment while we do it.
The Amarillo B Series should be rebuilt by an AGMA-experienced industrial gear shop with in-house gear cutting (hobbing and grinding) and NDT capability — not a general machine shop — and that is exactly the caliber of partner we route these jobs to. Combined with years in the industrial equipment business, that’s why the Cooling Tower units we handle come back right the first time. And if you have surplus Amarillo B Series units on the shelf, they carry real value — send the nameplate and we’ll turn them into cash.
