Fontana Hydraulic Pump Repair
A hydraulic pump sits at the centre of the machine, and its decline is usually gradual — delivery drops away as internal clearances open, until every function feels weak at the same time. Our Fontana workshop rebuilds piston, vane and gear pumps under its own roof and tests each one before release, so what you refit is a proven unit rather than a gamble.

Nothing ships until it is rebuilt and proven
Rebuilding a pump here involves taking it fully apart, measuring the rotating group, plates, housings and shaft, renewing whatever has worn, restoring working surfaces and verifying it on the bench. Contamination is examined in every diagnosis, because a pump that has swallowed metal debris will pass the same fate to its replacement unless the system gets cleaned.

Fontana hydraulic pump work · Fontana, CAWarning signs a pump is wearing out
A whining or cavitating note, functions that turn weak or sluggish — worst when hot — oil that foams or darkens, and metal showing in the filter all implicate either the pump or what feeds it. Starved inlets, from a collapsed suction hose to a choking strainer, destroy healthy pumps, which is why our diagnosis takes in the whole circuit and not only the component. Standard hours are Monday–Friday 6 AM–5 PM, the rush line runs 24 hours a day, and pick-up, delivery and quotes are free.

Hydraulic pump questions
Are hydraulic pumps tested once rebuilt?
Yes — no rebuilt pump leaves until testing, a mandatory stage of our process, has been completed.
Why did my replacement pump fail so soon after fitting?
Most often, contamination in the system or an inlet fault that nobody corrected. We diagnose the circuit alongside the pump, so the root cause gets fixed together with the component.
