Service Areas — California & Nationwide

American Gearbox Repair is based at 755 W. Rialto Ave, Unit B, Rialto, CA 92376. That is our only shop. We serve customers across California with pickup and delivery, and customers in Nevada, Arizona, Texas, Utah and nationwide by shipped-in repair and emergency pickup and delivery where arranged. Equipment is repaired at our Rialto shop — we do not repair equipment on your site, and we do not claim a local shop or branch in any other state or city.

Our services are the same wherever you are: industrial gearbox repair and rebuilding, custom gear manufacturing, industrial pump repair and hydraulic cylinder repair, with 24/7 emergency service, rush repairs in 24–72 hours on qualifying jobs, and a 24-month warranty on rebuilt units. Turnaround depends on the condition of the equipment, the parts required, job complexity and availability, plus shipping time for out-of-state work.

Choose your state below for the industrial areas we serve there and how to get equipment to us. If your state is not listed, call (714) 204-5167 — nationwide service means we can still help: ship the unit to our Rialto shop and we will inspect it, quote the repair and rebuild it.
