It is mounted on the inner side of the crankshaft flange, so the crankshaft needs to be processed at the former sealing surface. During an engine overhaul these changes can be easily done while grinding the crankshaft

Two different sealing kits for the crankshaft are available, both based on a modern radial shaft seal, designed to stop oil leakages. The sealing kits work on both types of engines, can be used with steel- or aluminium oil sumps and can be mounted with reasonable effort, as long as the crankshaft is removed.
Comprehensive installation instructions come with the kit.
