3. Disassemble the Cylinder Once the boom cylinder is detached, carefully disassemble it. Remove the end caps, which may require a specific tool or technique depending on your excavator model. Take care not to damage any internal components.

Additionally, customization of wiper seals is often necessary to meet the specific needs of a machine or application. Factors such as rod diameter, stroke length, and operating pressure are critical in the design process. Engineers often work closely with seal manufacturers to create solutions that provide optimal sealing performance under particular operating conditions.

Once the components are disassembled, remove the old seals. It's crucial to examine the seal grooves for any damage or debris, as this can affect the installation of new seals. Use a seal puller or appropriate tools to avoid scratching the cylinder surfaces.

Wiper oil seals often feature a unique design that includes a lip that contacts the shaft or surface it is sealing against. This lip creates a dynamic seal that adapts to the movement of the shaft, maintaining a tight enclosure even as the equipment operates. The design often includes an additional wiper or dust lip, which helps remove contaminants that come into contact with the seal, further enhancing its protective capabilities.

In various mechanical and industrial applications, seals play a crucial role in ensuring the longevity and efficiency of equipment. Among the many types of seals available, dust seals and oil seals are two predominant types that serve critical functions. While they may appear similar at first glance, their purposes, designs, and applications differ significantly. This article aims to explore these differences, helping you understand when and why to use each type.
