About American Gearbox Repair
Industrial gearbox repair and rebuilding, custom gear manufacturing, and industrial pump and hydraulic cylinder repair — done at our shop in Rialto, California, for customers all over the United States.
What We Do
American Gearbox Repair repairs, rebuilds and manufactures the equipment that keeps industrial operations running:
- Industrial gearbox repair & rebuilding: Inspection, diagnosis, repair and rebuilding of industrial gearboxes, including right-angle drives and speed reducers.
- Gear manufacturing: Custom gear cutting and manufacturing — spur, helical, bevel and other gear profiles — made to your specifications.
- Industrial pump repair: Diagnostic testing, component replacement and preventive maintenance for industrial pumps.
- Hydraulic cylinder repair: Inspection, resealing and rebuilding of hydraulic cylinders, plus hydraulic pump repair.
We repair gearboxes, gears and pumps from major brands — including Lufkin, Falk, Dodge, Hansen, Flender, Foote-Jones and Sumitomo. That is repair experience with those brands; it is not an affiliation with, or endorsement by, any manufacturer.
Our Shop in Rialto, California
Our shop is at 755 W. Rialto Ave, Unit B, Rialto, CA 92376. All repair work is done at our shop — we do not repair equipment at your site. Instead, we arrange pickup & delivery to bring your equipment to the shop and deliver it back to you when the repair is complete.
That pickup & delivery service runs nationwide, so customers anywhere in the United States can send equipment to us for repair, rebuilding or manufacturing.
Call us at (714) 204-5167 to talk through your equipment and the fastest path back to running.
How We Work
Straightforward repair, done properly and backed by a warranty.
Inspect First
We inspect and diagnose the equipment at our shop before deciding what the repair involves, so the work — and the timeframe — are based on what we actually find.
Repair & Rebuild
We repair or rebuild to restore reliable operation, replacing worn parts and validating performance before the equipment goes back to work.
24-Month Warranty
Our repair work is backed by a 24-month warranty, so you can put the equipment back into service with confidence.
Turnaround depends on equipment condition, required parts, job complexity and availability. On qualifying jobs, rush repairs can be completed in 24–72 hours, and 24/7 emergency service is available — call (714) 204-5167 any time.
