crankshaft rear. This kit replaces both types of original crankshaft seals.
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

The crankshaft in the XK engine is sealed with sealing cord or a scroll on the back of the crank. Both technical solutions have been state of the art the time, the engine has been designed and developed. Till today, both sealing methods are still usable, as long as you tolerate one or another oil drop underneath the car. But as soon as the engine gets an overhaul, it is time to think about a more appropriate sealing method.
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.
