In Schaumburg, a machine with a weak pump or a slow motor burns fuel and hours without getting work done. We handle hydraulic pump and motor repair in Schaumburg for excavators, skid steers, loaders, forklifts, and telehandlers.
Robert Marecki tests the pump or motor on your site first. If it needs a rebuild, he pulls it and rebuilds it at our Schaumburg shop. Call or text Robert for same-day response on urgent breakdowns.
Gear pumps run the loaders, forklifts, and skid steers on most Chicagoland sites. Worn gears and housings cause slow lifts and weak hydraulics. We rebuild or replace them and match the pump to your machine.
Piston pumps on excavators and larger loaders wear inside long before they fail outright. Scored pistons, worn swash plates, and bad bearings cut flow. We tear them down, measure every part, and rebuild them.
A machine that tracks to one side or won’t climb a grade often has a worn travel motor. We test drive and travel motors on excavators and compact track loaders, then repair or rebuild them.
Slow or jerky swing on an excavator points to the swing motor or its brake. We check case drain flow and pressure before removing anything. Worn swing motors get resealed or rebuilt in our shop.
Augers, trenchers, brush cutters, and cold planers on skid steers run hard on small hydraulic motors. We repair attachment motors that stall, leak, or lose torque, so the attachment pulls its weight again.
A slow machine is not always a bad pump. We test flow under load and measure case drain on your site. You know if the pump, motor, or a valve is at fault before money goes into parts.
1. You call or text Robert with the machine, symptoms, and location.
2. Robert tests flow, pressure, and case drain on-site in Schaumburg or across Chicagoland.
3. He confirms the problem is the pump or motor, not a valve or cylinder.
4. He removes the unit and rebuilds it at our Schaumburg shop.
5. We flush the system and replace filters so debris doesn’t kill the new parts.
6. We install the unit and test the machine under load.
Many slow machines get a new pump they didn’t need. The real fault can be a relief valve, a clogged filter, or a bypassing cylinder. In Schaumburg and nearby, we flow test under load before we pull anything.
Many pumps and motors can be rebuilt with new pistons, bearings, and seals. Some housings are too worn to save. Robert shows you what he found and gives you the cost before work starts.
Summer job sites in Aurora and Joliet push dust into tanks and breathers. Winter cold thickens oil, and pumps can starve on cold starts. Dirty or thick oil is the top cause of pump wear. We check oil and filters on every visit.
A failed pump spreads metal through the whole system. We flush lines, replace filters, and refill with the right oil. Then we test the machine under load before it goes back to work in Cook or DuPage County.
We work with excavation contractors in Elgin and Naperville whose excavators lose swing or travel power. We work with warehouse teams in Elk Grove Village and Addison whose forklifts lift too slowly. We work with landscapers in Arlington Heights whose skid steer attachments stall.
Weak hydraulics on a machine anywhere in Chicagoland? Call Robert before you buy a new pump.
Yes, we test, remove, and rebuild hydraulic pumps and motors for machines in Schaumburg and across Chicagoland. Testing and removal happen on your site. Rebuilds happen at our Schaumburg shop.
The most common signs are slow or weak hydraulics, a whining or knocking noise, and oil that runs hot. You may also see leaks at the shaft seal or foamy oil in the tank. Get it tested before the pump breaks apart and spreads metal.
Contaminated oil causes most hydraulic pump failures. Dirt, water, and metal wear down gears, pistons, and bearings. Low oil, air leaks on the suction side, and overheating also destroy pumps.
A whining pump is usually starving for oil, which is called cavitation. Low oil, a clogged suction strainer, or thick cold oil can cause it. A knocking or rattling sound often means air is getting into the suction line.
Rebuilding makes sense when the housing and shaft are still in good shape. If the housing is scored or cracked, replacement is the better choice. We inspect the parts and explain both options before any work starts.
A hydraulic pump turns engine power into oil flow. A hydraulic motor does the reverse and turns oil flow back into rotation. Pumps feed the system, while motors drive tracks, swing, and attachments.
We test a hydraulic pump with a flow meter under load, not just a pressure gauge. A worn pump can still make pressure but lose flow once the system is loaded. On piston pumps, we also measure case drain flow.
High case drain flow means oil is leaking past worn parts inside a piston pump or motor. The more it leaks, the less power reaches the work. It’s one of the clearest signs a rebuild is needed.
A slow or weak hydraulic motor usually has internal wear or is not getting enough flow. Worn seals, pistons, or gears let oil bypass inside the motor. We test flow to the motor and case drain to tell which one it is.
Hydraulic oil overheats when oil leaks inside worn pumps, motors, or valves. A relief valve that keeps opening, low oil, or a clogged oil cooler also adds heat. Hot oil breaks down fast and wears parts even faster.
Yes, you should flush the system after a pump fails. A failed pump sends metal through the lines, valves, and cylinders. Skipping the flush can ruin a brand-new pump in a short time.
Running a pump low on oil makes it suck air and starve, which damages it fast. The pump gets loud, runs hot, and wears out its internal parts. Shut the machine down and top off the oil before running it again.
