This hydraulic cylinder seal kit is designed to replace worn or leaking seals within the hydraulic cylinders of specific CAT loaders, ensuring proper system pressure and smooth operation. Manufactured to meet stringent material and dimensional standards, these seals provide superior resistance to wear and hydraulic fluid degradation compared to damaged or brittle seals. Operators may notice symptoms such as slow or jerky cylinder movement, external hydraulic fluid leaks, or a loss of lifting/actuation force when these seals fail.
Always verify with serial number before ordering.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Initial symptoms of failing hydraulic seals include external fluid leaks around the cylinder rod or casing, and sluggish or erratic cylinder movement. If left unaddressed, significant fluid loss can occur, leading to system pressure loss and reduced equipment functionality.
Carefully clean the cylinder bore and piston rod to remove any debris that could damage the new seals during installation. Avoid using sharp tools that could nick or cut the seals, ensuring they are seated properly without distortion.
Inspect the hydraulic fluid for contamination and check the condition of the hydraulic pump and filters when replacing cylinder seals.
