Amarillo Gearbox Repair
Amarillo right-angle gear drives rebuilt in our Rialto, CA shop — for cooling towers, agricultural irrigation and oilfield pumping nationwide.
Repair experience with Amarillo gearboxes
American Gearbox Repair repairs and rebuilds Amarillo Gear Company right-angle gear drives — the spiral-bevel units widely used on cooling tower fans, center-pivot and agricultural irrigation systems, and oilfield pumping equipment. Our repair experience covers Amarillo cooling tower gear drives, irrigation gearboxes and the right-angle drives that turn vertical motor power into horizontal fan or pump shafts.
Please note: we are not an authorized dealer or authorized service center for Amarillo Gear. We repair Amarillo equipment based on our repair experience, using inspection and rebuilding practices developed over years of working on right-angle gear drives.
Cooling tower and irrigation drives work in wet, dirty, outdoor conditions, so seal and bearing problems are common — and a failed fan drive on a cooling tower can shut down a whole plant. We inspect every unit completely before quoting, and we can often manufacture replacement spiral-bevel gearing in-house when parts are hard to find.
Common Amarillo gearbox problems we fix
- Spiral bevel gear wear and pitting — from continuous fan loads, shock and marginal lubrication
- Bearing failure — worn pinion and gear-shaft bearings causing noise, heat and fan vibration
- Oil and water seal leaks — failed seals letting water in and oil out in wet cooling-tower service
- Fan shaft and output shaft wear — scored seal journals and worn bearing seats
- Housing corrosion and bore wear — outdoor exposure corroding housings and fretting bearing bores
- Backlash and mesh problems — worn gearing causing clunking, vibration and poor fan performance
How we rebuild your Amarillo gear drive
1. Teardown and inspection
We disassemble the drive, clean all parts and measure bevel gear teeth, backlash, shaft runout and bearing fits. Water contamination and corrosion are checked carefully, since they are the usual culprits in cooling-tower service.
2. Gear and shaft repair
Worn spiral-bevel gears are re-cut or manufactured new to match the original set. Shafts are reground or replaced, bores are repaired, and corroded housings are cleaned and checked for soundness.
3. Reassembly and testing
New bearings, seals and gaskets are fitted, gear mesh and backlash are set, and the drive is run-tested for noise, temperature, vibration and leaks. Every rebuild is backed by our 24-month warranty.
Replacement components
Spiral-bevel gear sets, bearings, seals, gaskets, shafts, fan shafts, oil breathers and mounting hardware. When an Amarillo part is obsolete, our gear manufacturing capability lets us make a replacement instead of waiting on a long lead time.
