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.
Oil seals are generally constructed from materials that can withstand the specific chemical properties of the lubricant they are sealing. Common materials include rubber, silicone, and various elastomers. The design of an oil seal often incorporates a lip that rolls against a shaft or surface, creating a dynamic seal that can accommodate movement while maintaining its sealing capabilities.
1. Leak Prevention One of the primary functions of a hub oil seal is to prevent oil leaks. If the oil seal fails, the lubricant can escape, leading to insufficient lubrication of the bearings and other critical components. This can result in increased wear and tear, decreased performance, and eventually, catastrophic failure.
