This is a high-quality seal kit for the boom and bucket cylinders, essential for preventing hydraulic fluid leakage and maintaining system pressure. Constructed from durable NBR rubber and metal components, it offers superior sealing performance and longevity compared to worn or damaged seals that allow fluid bypass. Symptoms of failing cylinder seals include visible hydraulic fluid leaks around the cylinder rod, slow or jerky cylinder movement, and a loss of lifting or digging power.
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.
The first sign of failing cylinder seals is typically a visible hydraulic fluid leak from the cylinder rod or at the cylinder base. If left unaddressed, this can lead to a gradual loss of hydraulic pressure, causing slow or erratic operation of the boom and bucket. In severe cases, significant fluid loss can compromise the entire hydraulic system's functionality.
Thoroughly clean the cylinder bore and piston grooves before installing new seals to prevent contamination and ensure a proper seal. Always lubricate the seals with the appropriate hydraulic fluid before insertion to prevent tearing.
Inspect the cylinder rod for scoring or damage and the cylinder bore for wear when replacing the seals.
