FAQ

Q1: Is this seal for the front or rear of the crankshaft on the S6B engine?
A1: The part numbers 04865-18021 and 36211-01800 are typically used for the front crankshaft oil seal on the Mitsubishi S6B engine. It is crucial to confirm the exact location (front or rear) based on your engine’s service manual or the specific failure symptom before installation.

Q2: What tools or preparation are needed for installation?
A2: For a proper seal, ensure the crankshaft sealing surface and the seal housing in the engine block are clean, smooth, and free of old seal material, nicks, or burrs. Use appropriate seal driver tools for installation to avoid damaging the new seal. Applying a light coat of clean engine oil to the seal lip can aid installation.
