Installation & Application Notes

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.

Failure Symptoms

Initial signs of failure may include slow or weak bucket curling, or a slight hydraulic fluid leak from the cylinder rod. If ignored, the bucket's lifting and digging performance will progressively degrade, potentially leading to extended cycle times and reduced productivity.

Installation Tip

Ensure the cylinder bore is thoroughly cleaned of all debris and old seal material before installing the new seals. Avoid using sharp tools that could scratch or nick the new seals during insertion.

Service Note

Inspect the hydraulic fluid for contamination and check the condition of the hydraulic pump and hoses when replacing the cylinder and seal group.
