This Caterpillar Cylinder and Seal Group for the bucket is a crucial part of the hydraulic system, enabling the machine to perform digging and loading operations. Manufactured to meet rigorous OEM quality standards, it provides robust sealing and reliable cylinder performance compared to worn or leaking units. Operators may notice slow bucket actuation, external hydraulic fluid leaks around the cylinder, or a reduction in the bucket's breakout force when this assembly is failing.
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 initial symptom of a failing cylinder and seal group is often a slow or jerky bucket movement, accompanied by visible hydraulic fluid leaks from the cylinder rod or seals. If left unaddressed, the internal seals will continue to degrade, leading to a significant loss of hydraulic pressure and reduced lifting capacity. This can compromise the machine's ability to perform its intended tasks, leading to decreased productivity.
Ensure the cylinder rod is perfectly clean and free from any imperfections before installing the new seals. Avoid using sharp objects to pry seals into place, as this can easily damage them.
Inspect the hydraulic fluid for contamination and check the condition of the hydraulic lines connected to the cylinder.
