Hydraulic Pump Repair in Fontana
The hydraulic pump is the heart of the machine, and it usually dies slowly — flow falling off as clearances wear, until the machine is weak everywhere at once. Our Fontana shop rebuilds piston, vane and gear pumps in-house and tests them before release, so the pump you bolt on is a known quantity, not a hope.

Rebuilt and tested, or it does not ship
Pump rebuilding here means full disassembly, measurement of rotating groups, plates, housings and shafts, replacement of worn components, restoration of surfaces, and bench verification. Contamination is part of every pump diagnosis — a pump that ate metal needs the system cleaned, or the new pump eats the same meal.

Hydraulic Pump Repair in Fontana · Fontana, CASigns your pump is on the way out
Whining or cavitation noise, weak or slow functions especially when hot, foaming or discolored oil, and metal in the filter all point at the pump or its inlet conditions. Inlet problems — a collapsed suction line or starving strainer — kill good pumps, so the diagnosis covers the circuit, not just the component. Regular hours Monday–Friday 6 AM–5 PM; rush line 24 hours daily; free pick-up, delivery and quotes.

Frequently asked questions
Do you test hydraulic pumps after rebuilding?
Yes — testing is a required step in our process before any rebuilt pump is released.
Why did my new pump fail quickly after installation?
Usually contamination or an inlet problem that was never corrected. We diagnose the circuit along with the pump so the cause is fixed with the component.
