This crankshaft seal group is designed to prevent oil from leaking out of the engine crankcase along the crankshaft's rear main bearing journal. Manufactured with high-quality sealing materials that exceed the performance of a worn or hardened seal, it ensures a leak-free operation and maintains proper oil levels. A failing crankshaft seal may manifest as visible oil drips under the engine, a persistent burning oil smell, and a gradual drop in oil pressure if the leak is severe.
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 first indication of a failing crankshaft seal is typically the appearance of oil stains or drips on the ground beneath the rear of the engine. If ignored, the oil leak can worsen, potentially leading to low oil levels and increased oil consumption. A significant oil leak can also contaminate the clutch assembly, leading to premature failure of clutch components.
Carefully inspect the crankshaft's sealing surface for any nicks or grooves that could damage the new seal; polish if necessary. Avoid using excessive force or a standard screwdriver to pry the seal into place, as this can easily damage the seal lip.
When replacing the crankshaft seal, inspect the crankshaft itself for any scoring or wear on the sealing surface and check the condition of the flywheel and clutch.
