Hydraulics Service

Well-maintained hydraulic systems are essential for everything from heavy to compact construction equipment. However, hydraulic components are not like other parts. They are highly sensitive to contamination and often require service in clean room conditions. Specialized equipment and expertise are necessary for turning around jobs with a high level of confidence. The best way to keep your fleet working its best is to partner with a service provider that has the experience and the technology to get the job done right the first time.

At Carolina CAT, we’ve got you covered. Basically, if it uses hydraulic oil, we can service it. Our team has a long history of providing expert repairs and maintenance for cylinders, pumps, motors and valves, both by Cat® and allied brands.



We offer a variety of service options to help minimize cost and downtime. From building custom cylinders for your unique application to salvaging worn or damaged heavy equipment and industrial components, we can save you time and money.

There are many factors to consider when performing a repair: turnaround time, budget, component life and more. Our qualified service professionals can recommend a variety of options including:

  • Rerod, Retube, Hone, Straighten or Rechrome
  • Rebearing or Reseal
  • Remanufacture
  • Replace (OEM/Reconditioned/Exchange Parts)

We’ll get to know your fleet and your requirements, and recommend the right course of action for any job. As an authorized Cat dealer — and the company’s only representative in Western North Carolina — we pride ourselves on developing long-term relationships with the businesses we serve.
