What we repair

Hydraulic repair is our core. Everything under one roof.

Every unit is torn down, inspected, rebuilt and tested at our Lake Barrington shop, with machining, honing, re-chroming and seal fabrication done in-house.

Servo specialists

Servo valves & actuators, rebuilt and tested.

A sticking servo valve shuts down a press, a mill stand or a turbine. We repair servo valves, servo motors and servo-controlled actuators from Moog, Rexroth, Parker and others, then test them before they ship back to you.

  • Teardown report with findings before you approve the repair
  • Obsolete and discontinued servo parts sourced or reverse engineered
  • Direct OEM supply lines in Europe through partners in London and Italy

Common questions

Do you pick up outside Illinois?

Yes. We run hot shot pickup and delivery nationwide, 24/7, and quote the freight up front.

Will I know what failed before I pay for a rebuild?

Every job gets a teardown and inspection report. Nothing is rebuilt until you approve the quote.

Is repair cheaper than buying new?

In most cases, yes, and without the OEM lead time. If a unit isn't worth rebuilding, the report will say so.

Can you come to our plant?

Our field technicians handle on-site inspection, fluid and contamination testing and troubleshooting. Repairs are done in our shop.
