Whether you operate in Wisconsin’s manufacturing sector, Illinois construction and agriculture, or Minnesota’s heavy equipment industries, our team combines deep technical expertise with hands-on service that outperforms the standard distributor model.
We’re proud to be an Authorized LHY Powertrain Distributor and Service Center, offering precision-built hydraulic components, hydraulic diagnostics, and remanufacturing under one roof. When you need power, control, and reliability — we build it, test it, and stand behind it.
What Makes Us Different?
We’re Not Just a Distributor. We’re the Solution.
MJ Hydrostatics is one of the few hydraulic service providers in the U.S. that offers:
- Authorized LHY Powertrain distribution
- In-house hydrostatic and hydraulic repair and remanufacturing
- Custom hydraulic system design and diagnostics
- On-site testing, prototyping, conversions, and validation
Most distributors rely on manufacturers. We do the work ourselves.
Complete Hydraulic System Solutions
Our goal is simple: to create smarter, stronger, and longer-lasting hydraulic systems. Every component we service or design is backed by years of field experience and modern diagnostic testing to ensure you get unmatched performance.
Hydraulic Power Units
We specialize in designing and building custom hydraulic power units for industrial and mobile applications. From open-loop and closed-loop hydraulic systems to variable and fixed displacement pumps, every unit is engineered for your specific performance and flow requirements.
Hydraulic Pump & Motor Repair
Our technicians perform complete teardown, inspection, and hydraulic pump and motor repair with load testing and calibration to ensure OEM-level results. We handle piston pumps, gear pumps, vane pumps, and more — all rebuilt, tested, and validated in-house.
Hydraulic System Design & Engineering
Our hydraulic system engineering team creates turnkey designs that maximize efficiency and minimize downtime. We design everything from hydraulic circuit layouts and filtration systems to electro-hydraulic control systems and proportional control valves — each tailored to your machine’s real-world environment.
Diagnostics, Testing & Calibration
We don’t guess — we test. Our hydraulic diagnostics and testing services identify root causes, verify flow performance, and ensure your hydraulic components operate at full capacity. On-site or in-shop, our technicians deliver accurate results without relying on third-party labs.
Component Sales & Remanufacturing
As a trusted LHY Powertrain distributor, we supply and rebuild components from leading manufacturers including Linde Hydraulics, Parker Hannifin, Danfoss, Bosch Rexroth, Eaton, Denison, ASA Hydraulics, and Kawasaki. From hydraulic valves and coolers to manifolds and cylinders, we have the parts and expertise to keep your system performing.
Industries We Serve
Our work powers a wide range of industries throughout Wisconsin, Illinois, and Minnesota — helping clients stay productive through every season and application.
- Mobile Hydraulic Systems: For construction and transportation fleets needing reliable power and smooth control.
- Industrial Hydraulic Systems: Designed for factories, presses, and manufacturing operations that demand consistent hydraulic performance.
- Agricultural Equipment: From combines to loaders, we support the hydraulic systems that keep Midwest farms running strong.
- Marine & Heavy Equipment: Specialized hydrostatic drive systems and power transmission components engineered for performance and durability.
- OEM Partnerships: We assist equipment manufacturers with custom hydraulic systems, hydraulic testing benches, and prototype development to accelerate innovation.
What Sets MJ Hydrostatics Apart
While most shops either sell parts or send repairs elsewhere, we handle design, repair, testing, and prototyping all in one facility. That means faster turnaround, better pricing, and total control over quality.
