This is a crankshaft front oil seal, essential for preventing lubricant from escaping the engine's crankcase at the front pulley end. Manufactured from high-grade synthetic rubber and steel, it maintains a tight seal against the rotating crankshaft, unlike a brittle or torn seal that allows oil to escape. Operators might observe oil dripping from the front of the engine, a burning oil smell, or a low oil level warning if this seal fails.
Always verify with serial number before ordering.

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.
The most common symptom is oil leakage observed around the engine's front pulley and harmonic balancer. If ignored, the leak can intensify, leading to significant oil loss and potential engine damage from low oil pressure. Persistent oil leaks can also contaminate other engine components and create a fire hazard.
Carefully inspect the crankshaft snout for any nicks or burrs that could damage the new seal during installation. Ensure the seal is pressed in perfectly square to prevent premature failure.
Inspect the crankshaft pulley, front cover gasket, and timing belt/chain for wear or damage when replacing the crankshaft front oil seal.
