Good To Know

Q: What does a crankshaft oil seal do? A: It seals the crankshaft where it exits the crankcase, keeping oil inside the engine and contaminants out. A worn seal often shows as oil seepage or drips near the crankshaft area.

Q: How do I confirm this seal fits my engine? A: Compare the OEM number 6S5-81167-10-00 against your parts diagram and verify your model year falls within the stated range. Checking your serial number against the parts catalog is the safest way to confirm.
