Description
The mainshaft seal is a critical component that prevents transmission fluid from leaking into your primary case, a common failure point on Big Twin engines. A worn or degraded seal will cause oil loss, contaminate your primary fluid, and accelerate wear on internal components. Replace it with a precision-engineered JAMES GASKET seal to restore a reliable barrier and maintain proper lubrication where it matters most.
