This oil seal is designed to prevent lubricant from escaping a rotating shaft and contaminants from entering a housing, commonly found on excavator final drives or hydraulic components. It is manufactured with high-quality sealing materials to maintain its integrity under pressure and temperature variations, unlike a worn seal that becomes brittle or loses its sealing lip. Operators might notice oil leaks around the shaft or bearing housing, or hear increased noise from the component if this oil seal is damaged or worn out.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first sign of a failing oil seal is typically a visible oil leak originating from the shaft or housing where the seal is located. If the leak is not addressed, the lubricant level will decrease, potentially leading to increased friction and wear on the protected component. Continued operation with a leaking seal can result in component damage due to insufficient lubrication or contamination.
Carefully inspect the shaft for any burrs or damage that could nick the new seal during installation. Use a proper seal driver or a clean, flat surface to press the seal in squarely, avoiding cocking it in the bore.
When replacing an oil seal, inspect the shaft for scoring or wear, and check the bearing or component it protects for any signs of damage or contamination.
