Five Levels of Repair Options

12-Month Cat® Parts Warranty


  1. Make the best choice to protect hydraulic performance and your bottom line. From the most basic repair to a full rebuild or replacement, genuine Cat® hydraulic cylinders and rods give you the options to fit your needs every time.
  2. Maximize your uptime by getting parts where you need them. Most cylinder and rod parts are available to ship within 24 hours.
  3. Work worry-free knowing that Cat covers the parts and even more when installed by your local dealer. Did you know that no competitor covers resultant damage when a part fails? When your Cat dealer installs the parts, both repair labor and resultant damage are covered. That is part of the genuine Cat parts warranty advantage. For piece-of-mind you can trust, choose genuine Cat parts. A cylinder failure repair can cost over $100,000 if other parts are damaged and a hydraulic system clean-out is needed. Contact your Cat dealer for full warranty details.

Common causes
of cylinder failure

High usage and harsh site conditions make major contributions to cylinder failure. Impact, corrosion and abrasion all take their toll, too, which can lead to serious machine performance issues. But surprisingly, 75-85% of hydraulic system failures are traced to contamination issues*. Simply keeping your hydraulic fluid clean through smart contamination control can significantly reduce cylinder failures and repair/replacement costs.
