How To Repair Hydraulic Cylinders

Even though hydraulics is an uncommon name in the machining industry, which can abundantly find its applications everywhere, hydraulics is an applied science that uses the mechanical properties of fluids to build systems that can perform heavy-duty jobs precision.

From bulldozers and tractors to elevators, nearly all the latest technological developments employ specific hydraulic machinery to make the machine more efficient and reliable.

A typical hydraulic system has two parts, namely a pump and a cylinder. While the former generates pressure, the latter is involved in performing the mechanical action using the received pressure.

Considering the essentiality of a hydraulic cylinder to its system, who can say that any damage or inefficiency in its parts can lead to poor work output.

Tips To Repair Hydraulic Cylinders

Hence, hydraulic cylinder manufacturers advise technicians to keep the cylinder repair guide handy. Here are the steps that dictate cylinder repair and rebuilding jobs:

#1. Disassembling Every Unit from the System

The preparatory measures for performing a satisfactory cylinder repair job are carefully removing the cylinder from the system and placing it in a safe environment. Once that has been done, the cylinder is ready to be disassembled. Firstly, the cover end of the cylinder is removed from the shaft’s side.

It is achieved by unscrewing or unbolting it. Removal of the cover, screws, or bolts loosens the grip of the valves, thereby ejecting the piston from the system. Who must ensure that the piston is removed from its shaft as well as the cylinder consecutively?

Hydraulic cylinder manufacturers often supply a definitive instruction book for the same with every new purchase.

#2. Locating the Issue and Inspecting Other Parts

With the piston removed from the cylinder, it becomes easier to inspect every internal part for damages. Common problems like bent cylinder rods, crack in the cylinder surface, broken seal, and piston damages can be treated with some tactful hacks, though it is better to consult trained technicians for completing the task.

#3. Repackaging the Cylinder Seal

This step requires a seal kit that is designed as per the measurement of one’s cylinder. It includes all the necessary seals and O-rings, which are used to replace the damaged pieces.

Hence, it is better to consult experienced hydraulic cylinder manufacturers for more satisfactory output to gain valuable help in understanding the seal kit components.

The first step of seal repackaging is removing the old damaged seals from their specific locations, keeping in mind the particular ways they were installed. Ideally, every seal must be removed and replaced with a new one simultaneously. However, who must ensure that the new seals are not damaged in the process?

#4. Putting Cylinder Parts Back Together

Once the damaged internal parts have been replaced and new seals have been installed, one can begin reassembling the complete cylinder. As the first step, the seals must be oiled with a sufficient amount of hydraulic fluid.

Once all the seals are appropriately oiled, who can slide the piston back into the cylinder? This process becomes complicated when the valves are not loosened sufficiently from the first step. Thus, the valve tightness must be checked, and who must slide the piston into the cylinder.

The moment the piston is interlocked with all the seals, then the cap can be bolted atop again. Hydraulic Cylinder Manufacturers are the best guides for repairing or rebuilding a hydraulic system, mainly when the problem arises from its hydraulic cylinder.

A mere lag or negligence in the disassembly or reassembly process can result in the complete breakdown of the system. Hence, the process must be carried out very carefully.
