Heavy-Duty Hydraulic Pump Repair
Oilgear, Rexroth, Parker, Eaton and other high-value hydraulic pumps rebuilt to hold rated pressure — for presses, steel mills, forging equipment and hydraulic power units. 24-month warranty, nationwide service.
Heavy-duty hydraulic pumps, rebuilt to hold pressure
Hydraulic pumps are the most expensive wear item in a hydraulic system — and the one where a proper rebuild saves the most money. We rebuild high-value hydraulic pumps in our Rialto, CA shop: axial and radial piston pumps, variable displacement pumps, vane pumps, gear pumps and high-pressure units for presses, steel mills, forging equipment and hydraulic power units. A rebuilt pump that holds rated pressure is worth far more than a cheap repair that leaks down under load.
Oilgear Pump Repair
Oilgear is our specialty — high-pressure axial piston pumps and hydraulic systems from presses and mills, rebuilt to original tolerances with a 24-month warranty.

Press, mill and power-unit service
Our heaviest hydraulic work comes from hydraulic press, steel mill and forging press systems, where a pump failure stops a whole line. We rebuild the pump, repair the hydraulic motor and valves, and service the complete hydraulic power unit — so the system goes back together working as a unit, not as a collection of separately repaired parts. See our dedicated forging press & hydraulic equipment repair page, and our hydraulic cylinder repair page for the cylinders those systems drive. We also rebuild the gearboxes behind the pumps — see gearbox repair — and serve the industries that run this equipment. Turnaround depends on equipment condition, required parts, job complexity and availability; rush repairs of 24–72 hours are available on qualifying jobs, with 24/7 emergency service and emergency pickup & delivery to our shop. Every rebuild carries our 24-month warranty. Call (714) 204-5167 or request a quote.
How a rebuild works
Every pump or cylinder that comes into our Rialto, CA shop is disassembled, cleaned and inspected before we quote. We measure wear, check clearances against the manufacturer’s tolerances, identify the failed parts, and give you a straight answer: rebuild it, repair the failed section, or replace it. Turnaround depends on equipment condition, required parts, job complexity and availability. All rebuilds are backed by our 24-month warranty.
