Protect your hydraulic system with genuine Cat parts and achieve peak performance throughout the life of your machine. Your Cat® hydraulic system is designed to withstand high pressures to meet the demands of your machine. Contamination and component damage can lead to reduced efficiency and unplanned downtime. That's why a well-maintained hydraulic system is critical to achieving maximum performance and value over the life of your machine. Every component in your hydraulic system is vital to the performance of your operation, and it all depends on the ability to perform under pressure. "Genuine Cat parts are uniquely designed for performance, durability and seamless integration into a highly refined hydraulic system," said Fabrice Trolio, Caterpillar hydraulic component applications specialist. "That's why it's critical that you always use genuine Cat parts." There are three main groups of components to consider: hoses and couplings, cylinders and rods, and pumps and motors.








Cat Hoses and Couplers

Engineered for durability and corrosion resistance, Genuine Cat hoses and couplings provide industry-leading flexibility and can help increase machine reliability and safety. Cat hoses and couplings are tested together as a system to provide maximum performance in a wide range of applications.

Cat Cylinders and Rods

Genuine Cat cylinders and rods help provide the optimum balance of strength, surface finish and impact resistance. Cylinder seals are faceted and roll polished for superior sealing performance. Components work together to help ensure greater resistance to contaminants.

Cat Pumps and Motors

Genuine Cat pumps and motors are built to tight tolerances and tested to meet the stringent performance and strength requirements of the Cat hydraulic system. These components are matched to your machine's unique controls and configurations to help optimize performance and maximize team productivity.

Do not wait for failure

It is very important to keep an eye on the efficiency of your hydraulic system. It can erode significantly before you notice a problem. That's why it's vital to help prevent failure by performing proper maintenance and relying on the support of your local Cat dealer. There are three key areas of maintenance to consider: prevention, detection, and inspection.



  • Perform regular maintenance by changing and monitoring the oil, performing daily inspections and looking for signs of wear.
  • Know the causes and effects of pollution.



  • Your Cat Dealer provides Scheduled Oil Sampling (S•O•S) services to help detect problems in the hydraulic system.
  • Help improve downtime scheduling and budget management by predicting your machine's repair needs.



  • Check for leaks and don't ignore excessive noise or vibration.
  • Inspect your machine for signs of damage, loose or missing hardware, and to help monitor hydraulic system cycle times and drift rates.


It's always good to listen to expert advice. On the benefits of fixing before failure, Trolio said: “It helps reduce costs for the customer. You can plan downtimes and avoid high repair costs after a failure occurs. Dealers can provide a range of detection services to support the pre-failure approach, such as S•O•S service analysis.” The hydraulic system is the lifeblood of your business, and there is almost no hydraulic problem that your Cat dealer has not dealt with before.
