1m-8746 Floating Seal — Cat 3406 3306

This floating seal is a crucial sealing component designed to prevent the ingress of contaminants and the egress of lubricants in rotating assemblies. Manufactured to meet exacting OEM standards, it provides a reliable seal superior to worn or damaged seals that leak or allow debris entry. Operators may notice lubricant leaks, increased wear on mating surfaces, or audible signs of contamination if 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 visible lubricant leakage around the axle or final drive housing. If ignored, this leakage will continue, potentially leading to a low lubricant level and increased wear on gears and bearings due to lack of lubrication. The ultimate consequence of a failed seal is severe internal component damage from abrasive wear and insufficient lubrication.

Installation Tip

Ensure the mating surfaces on both the shaft and housing are perfectly clean and free of any burrs or imperfections before installing the seal. Press the seal components in evenly and squarely to prevent cocking, which can compromise the seal's integrity.

Service Note

When replacing floating seals, always inspect the shaft and housing surfaces for scoring or wear that could affect the new seal's performance.
