1. Fluid Leaks The most obvious indication that a hydraulic seal needs replacement is the presence of hydraulic fluid leaking from the system. Any visible fluid outside of the designated compartments is a red flag.

2. Remove the Boom Cylinder Start by detaching the boom cylinder from the excavator. This typically involves removing the pins and bolts that secure the cylinder to the boom and the attachment points. Use a hydraulic jack to support the cylinder as you loosen the connections.

A rotary shaft seal is a critical component that provides a barrier between the rotating shaft and the static housing. They are commonly used in machinery subjected to high pressure and dynamic motion, such as hydraulic systems, turbochargers, and rotary actuators. The design of high pressure rotary shaft seals is specifically tailored to withstand not only high pressures but also extreme temperatures and aggressive media, which are often encountered in industrial environments.

1. Prevention of Fluid Leakage The primary function of the oil seal is to prevent fluid leakage, which can result in inadequate lubrication and increased wear on moving parts.

3. Aerospace High-pressure oil seals are essential in aerospace applications, where they are used in engines and landing gear, where they withstand not only high pressures but also extreme temperatures and environmental conditions.
