1697827 Stick Cylinder Seal Kit — Cat 330D 325D

This stick cylinder seal kit is essential for maintaining hydraulic system integrity in CAT equipment, preventing fluid leaks and ensuring proper cylinder function. It is manufactured with high-quality sealing materials that resist wear and degradation, outperforming worn or cracked seals. Operators may notice external hydraulic fluid leaks around the cylinder rod, sluggish boom or stick movement, or a loss of hydraulic pressure.

Installation & Application Notes

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.

Failure Symptoms

The first indication of a failing seal kit is often visible hydraulic fluid leakage around the cylinder rod. If unaddressed, the leakage will worsen, leading to a gradual loss of hydraulic power and slower cylinder actuation. Continued operation risks significant hydraulic system contamination and potential cylinder damage.

Installation Tip

Thoroughly clean the cylinder bore and rod before installing new seals to prevent damage and ensure a proper seal. Never use sharp tools to pry seals into place; use appropriate seal installation tools.

Service Note

Inspect the cylinder rod for scoring or damage, and check the hydraulic fluid for contamination when replacing the stick cylinder seal kit.
