hydraulic jack seal repair kit

The seals in an excavator's boom cylinder are designed to prevent hydraulic fluid from leaking out and to keep contaminants from entering the hydraulic system. If these seals become worn or damaged, you may notice several issues. Common signs include hydraulic fluid leaks around the cylinder, decreased lifting power, and irregular operation of the boom. Ignoring these issues can lead to more severe problems, including complete hydraulic failure, which can result in costly repairs and downtime.

1. Surface Preparation Ensure that the sealing surfaces are clean and free of debris before installation.

The primary function of axle hub seals is to retain lubrication. Proper lubrication is essential for the smooth operation of moving parts, reducing friction and wear. Without effective sealing, the lubricant can leak out, leading to inadequate lubrication of the gears and bearings, which may cause premature wear and eventual failure of the components.

2. Static Seals These seals are designed for applications where there is no relative motion between the sealing surfaces. They are often used in hydraulic cylinders and various types of machinery where oil containment is critical.

Carefully remove the hydraulic cylinder from its mounting. Use the manufacturer’s manual for guidance to avoid damaging any components during disassembly. Remove the end caps, and gradually extract the piston and rod.
