Description
A failing inner primary bearing seal is one of the most common sources of oil weeping in Big Twin motors—and it’s a problem that compounds quickly if left unaddressed. The JIMS 8961 replaces the original seal with precision-engineered construction that stops leaks at the source, restoring a dry primary case and protecting your engine’s longevity. This is a straightforward bolt-on replacement that pays dividends in reliability and cleanliness.
