109-0885-6y-5318 Floating Seal — Cat 3306

This is a floating seal, also known as a duo cone seal, designed to maintain lubrication and prevent contamination in heavy-duty rotating applications like final drives and hydraulic systems. Manufactured to meet rigorous OEM standards, it offers superior sealing performance and longevity over worn or damaged seals. Operators may observe oil leaks, excessive dirt ingress into the component, or unusual noises from the affected drive or system when this seal fails.

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 floating seal is often a visible oil leak around the component. If left unaddressed, this can lead to increased wear from lack of lubrication and contamination of internal components. Continued operation with a compromised seal risks severe damage to gears, bearings, or hydraulic components.

Installation Tip

Carefully inspect the mating surfaces for any nicks or burrs that could damage the seal faces upon installation. Ensure the seal is installed perfectly square to avoid uneven wear.

Service Note

Inspect the mating surfaces, seal grooves, and associated bearings for wear or damage when replacing floating seals.
