1 x SE823. XK120 Front Crankshaft Modern Seal Conversion Kit. This is our own, very sucessful conversion, designed by a top Jaguar racing specialist for us 25 years ago. This kit replaces the notoriously leaky, 2-piece, front rope seal that Jaguar fitted to this period of engine, that not only features 2 joints to leak from, but also often picks up and spins in the housing!

Our kit consists of a newly made crank follower ring, precisely made (not original Jaguar diameter), to perfectly fit the supplied new one-piece seal. A very straight-forward replacement kit that can be easily fitted with the crankshaft still installed.

We highly recommend fitting this conversion, in conjunction with our C-Type Hydraulic Timing Damper kit (SE822) to any XK120 type block that you rebuild, to solve the two most annoying classic design faults in this superb engine.
