It is mounted on the outside of the crankshaft flange, so the crankshaft needs to be processed. The oil seal ring uses the flywheel flange as an opposite, so the processing of the crankshaft is marginal. Additionally the flywheel needs to be milled out on the engine side. So this kit can't be used if the car is equipped with automatic gearbox

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.
