Caterpillar hydraulic cylinders are known to be high-quality and can stand up to years of wear and tear, however, they’re not immune to seal degradation and breaking down.

We Repair

Most Common Caterpillar Hydraulic Cylinders We Repair

Whether it's a bulldozer blade lift cylinder, an excavator boom cylinder, or any other type of Caterpillar cylinder, Cylinders, Inc. has the expertise and experience to provide top-quality repairs that meet or exceed industry standards.


Types of Caterpillar Hydraulic Cylinder Repairs We Handle

Before the point of total replacement is necessary, Caterpillar hydraulic cylinders can usually be repaired in three main ways. Whether or not the repair is possible depends on how much internal damage has been caused. Regardless of the issue, our team can handle all sorts of Caterpillar hydraulic cylinder repairs.

We take on:

  • Reseals. This means installing new seals and wear rings that are between the metal parts. Releasing typically involves a mixture of dynamic seals for the moving parts and static seals around the piston and rod.
  • Repairs. If the warning signs are caught early, hydraulic cylinders can be restored to their original condition.
  • Rebuilds. Old or worn-down components are replaced and any reusable parts are salvaged accordingly. This is a cost-effective approach.

Frequently Asked Questions

How much does it cost to repair a Caterpillar hydraulic cylinder?

The cost of repairing a Caterpillar hydraulic cylinder varies depending on the extent of the damage and the cost of replacement parts. At Cylinders, Inc., will provide you with a quote for the repair once we have assessed the cylinder.

What’s your turnaround time for Caterpillar hydraulic cylinder repairs?

Providing our clients with fast turnaround times is essential to us at Cylinders, Inc.! While the specific amount of time for each repair differs, we are always transparent and communicative so you know what to expect throughout the process.

How do I know my Caterpillar cylinder is out of order?

Contamination and rod damage are leading causes of Caterpillar cylinder failures. Some operators may miss early warning signs and not realize the cylinder is failing until unscheduled downtime is needed. This is common as efficiency losses come on slowly.

Here are some red flags to be aware of when operating your Caterpillar hydraulic cylinders:

  • Contaminated oil;
  • Unexplained leaks;
  • Damaged seals or bent rods;
  • Increased cycle times;
  • Decreased speed and productivity.
