Hydraulic Service & Repair Certificate

Students can complete a certificate program to develop another area of expertise in addition to their major, or as a stand-alone 9-month program that focuses on technical skills. See the link at the right for the course sequence / curriculum.

The Hydraulic Service and Repair program prepares students with the basic knowledge and skills to get started in the rebuilding and repair of hydraulic equipment. Graduates of this program will be highly effective employees for firms with off-road machinery that utilizes hydraulics, including the agriculture, construction, and mining industries.

Technical instruction includes course work in fundamentals of fluid power, technical graphics and CAD, methods of power transmission, fluid power components, microcomputers, DC electricity and electronics, digital controls, fluid conveyance, fluids and filters, metal fabrication, and instrumentation/troubleshooting.

Employment opportunities exist with firms who specialize in the repair or rebuilding of fluid power components. Because rebuilding is often more cost effective and quicker than buying new components, many large industrial users and manufacturers seek individuals with these skills for maintenance positions. Most industrial plants and mobile equipment owners elect to rebuild their hydraulic and pneumatic equipment because of the complications often experienced in obtaining replacement pumps, valves, motors, and cylinders, and due to the high cost of these items.


Ohio State ATI’s students study in a 15,000-square-foot facility which features fully-equipped fluid power and diesel system laboratories. The facility includes laboratory accommodations for hydraulics, pneumatics, gasoline and diesel engine, power transmission, air conditioning, welding, electronics, and metal fabrication training. Our state-of-the-art equipment includes:

• Cummins ISB diesel engine with integral fluid power dynamometer and computerized diagnostic equipment
• Hydraulic systems and trainers for four didactic levels of hydraulic technology training
• Pneumatic fluid power trainer modules
• Fuel systems training and demonstration equipment
• Computer-integrated, multi-channel, mobile data acquisition system (DAQ) and monitoring and analysis software
• Industry-standard Recovery/Recycle/Recharge Automatic Refrigerant Management System

In addition to campus facilities, the 1,700-acre Ohio State ATI Farm is used for training and demonstrations utilizing the latest agricultural equipment.
