Power Generation Gearbox & Pump Repair
Turbine support, cooling and fuel-handling drives rebuilt for reliable, continuous operation — with emergency pickup when generation is at risk.
Gearbox & Pump Repair for Power Generation
Rebuilt at our Rialto, CA shop.
Power plants run on reliability. A failed cooling pump, fuel-handling drive or turbine support gearbox can take a unit offline, and the cost of that outage is measured in hours, not parts. American Gearbox Repair rebuilds power generation gearboxes and pumps at our shop in Rialto, California, serving gas, hydro, biomass, solar-support and industrial power operations across California and nationwide by pickup, delivery and shipped-in repair.
We rebuild the auxiliary drives and pumps that generation depends on, and we work to planned outages as well as to emergencies. Every unit is inspected and quoted before work starts, and rebuilt units are covered by our 24-month warranty.
Equipment We Repair in Power Generation
- Cooling water and circulating pumps — large centrifugal pumps and their gearboxes, rebuilt for continuous duty.
- Fuel handling drives — gearboxes on conveyors, feeders and crushers moving coal, biomass or waste fuel.
- Turbine support gearboxes — auxiliary drives associated with turbine systems, inspected for gear, bearing and alignment condition.
- Hydro plant drives — gearboxes on gates, hoists and auxiliary equipment in hydroelectric plants.
- Fan and blower drives — gearboxes on forced-draft, induced-draft and cooling-tower fans.
- Hydraulic cylinders — cylinders on gates, valves and handling equipment, resealed and tested.
Common Failures We See
- Bearing and gear wear from continuous duty — long runs with little time for inspection between outages.
- Cooling water corrosion and erosion — in pumps and in drives exposed to treated and untreated water.
- Misalignment and vibration — from thermal movement, foundation settling and coupling wear.
- Seal failure and oil contamination — letting water and dust into gearboxes.
- Pump cavitation and impeller wear — reducing flow and efficiency on cooling and feed service.
Repair & Rebuilding Services
- Complete gearbox rebuilding — teardown, cleaning, inspection and rebuild with new gears, bearings, seals and shafts as required.
- Industrial pump repair — cooling, circulating, feed and transfer pumps rebuilt and tested.
- Custom gear manufacturing — replacement gears cut when the original is worn, broken or no longer stocked.
- Hydraulic cylinder repair — reseal, re-rod and re-hone for power-plant cylinders.
- Outage planning support — inspection and quoting timed to your planned outage, so rebuilt units are ready when the plant stops.
Emergency & Rush Service
When a line is down, call (714) 204-5167 — emergency service is available 24/7. We arrange emergency pickup and delivery to our Rialto shop, prioritise inspection, and, on qualifying jobs, complete rush repairs in 24–72 hours. Rush timing depends on unit condition, parts availability and job complexity, so we confirm a realistic schedule after inspection. See our emergency repair page.
How a Repair Works
Repairs are done at our shop in Rialto, California — we do not repair equipment on your site. Ship your unit to us, or arrange emergency pickup and delivery. We inspect it, confirm the failure and parts needed, and quote the repair before work starts. Turnaround depends on equipment condition, parts required, job complexity and availability. Rebuilt units are tested where applicable and covered by our 24-month warranty. Call (714) 204-5167 or request a quote with the brand, model and problem.
Get Started
For a power-plant drive or pump problem, call (714) 204-5167 early — planned-outage work is always easier to schedule than an emergency rebuild, and early inspection usually keeps the repair smaller. Call (714) 204-5167 or request a quote.
