This boom lift cylinder seal kit is designed to replace worn or leaking seals within the hydraulic cylinder responsible for lifting and lowering the loader's boom. It is crucial for maintaining hydraulic pressure and preventing fluid leaks, ensuring smooth and controlled boom operation. A failed seal kit will typically result in a slow-lowering boom, visible hydraulic fluid leaks around the cylinder, or a boom that drifts down under load.
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 most common symptom of worn boom cylinder seals is a noticeable drift or slow lowering of the boom when the hydraulic control is not engaged. This can progress to visible hydraulic fluid leaks from the cylinder rod seal or internal leakage causing reduced lifting capacity. If left unaddressed, significant fluid loss can occur, potentially leading to system contamination and damage to the hydraulic pump.
Carefully clean the cylinder bore and piston rod before installing new seals to prevent damage from debris. Ensure all seals are properly oriented and seated before reassembling the cylinder.
Inspect the hydraulic cylinder rod for scoring or damage, and check the hydraulic fluid for contamination when replacing the boom lift cylinder seal kit.
