Cylinder Repair Warning Signs

Contamination is responsible for the majority of hydraulic cylinder failures. Operators may miss the early warning signs, as efficiency losses come on slowly, and may not be noticed until it’s too late.

Operators may be able to detect issues early if they are trained to look for these early warning signs:

  • Unexplained Leaks
  • Contaminated Oil
  • Damaged Seals
  • Increased Cycle Times
  • Decreased Speed & Productivity

Types of Caterpillar Hydraulic Cylinder Repairs

Before total replacement, Caterpillar hydraulic cylinders can typically be repaired in one of three ways, depending on the amount of internal damage.

  • Reseals: This kind of repair involves sealing any gaps between parts. Typically, it can involve a mix of dynamic seals for the parts in motion and static seals around the rod and piston. Undamaged core components are returned to their place inside the cylinder.
  • Repairs: When early warning signs are identified, hydraulic cylinders can often be repaired back to their original condition. This involves repairing slightly damaged components quickly and efficiently.
  • Rebuilds: In rebuilds, old, worn components are replaced, and reusable parts are salvaged for use in the cylinder. This is a cost-effective option when compared to full replacements.

Fixing a leaking seal without relying on an expert seems like a wise choice on the surface. The challenge is that this quick and cheap fix may be hiding a longer-term issue that will only worsen over time. If the leaky seal indicates an internal failure, then the fix becomes a risky proposition as the cost of repairs increases the longer the real problem goes unnoticed.

Choosing the Right Caterpillar Hydraulic Cylinder Seal Repair Service

Knowing which repair you need can be a complicated decision to make, and it’s one that you don’t have to make on your own. We always recommend turning to a professional for hydraulic cylinder seal repairs. Our specialists have many years of experience and can help you find the right solution. Before we recommend any repair service, we always perform a thorough evaluation.

How Do You Replace a Caterpillar Hydraulic Cylinder Seal?

If you already have some experience, and want to replace your seals on your own, we recommend purchasing one of our convenient seal kits. Read our guidelines below to ensure proper replacement:

First, make sure you’re confident that the leaky seal is not a result of another internal issue. If you fail to address the real problem, you may wind up with costlier repairs or possibly need a full cylinder replacement. Second, ensure that you’ve purchased the right seal kit. Third, identify where you will place your components while working on the reseal. Follow appropriate safety measures to protect yourself.

Now you’re ready to get started! Make sure the pressure has been fully released from the cylinder before removing the gland. Then, pull the piston rod out of the motor and place it in a location that is free from dust and debris. Snap a photo of the components, so you remember the order that you took them apart.

Replace the seal or O-ring as needed in the gland or piston. Make sure all parts are well-lubricated before reinstalling the cylinder. Finally, start up your machine and test for leaks.
