This boom cylinder seal kit is essential for maintaining the integrity of the hydraulic boom cylinder, preventing internal and external leaks of hydraulic fluid. It is manufactured to precise dimensions and material standards, ensuring a reliable seal that prevents pressure loss and contamination, unlike a worn kit. Operators may notice slow or jerky boom movements, hydraulic fluid leaks from the cylinder, or a loss of lifting capacity when this seal kit fails.
Always verify with serial number before ordering.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Visible hydraulic fluid leakage from the boom cylinder, particularly around the rod or gland, is the first sign of a failing seal kit. If ignored, the leaks will worsen, leading to a gradual loss of boom control and potential contamination of the hydraulic system. This can result in reduced excavation efficiency and increased wear on hydraulic components.
Before installing the new seals, carefully inspect the cylinder rod and bore for any imperfections that could damage the seals. Ensure all old seal material is meticulously removed from the grooves to guarantee a proper fit and seal.
Inspect the boom cylinder rod for pitting or scoring, and check the hydraulic fluid level and condition when replacing the boom cylinder seal kit.
