CRANKSHAFT REAR SEAL CONVERSION

This kit consists of a small aluminium housing which holds a split lip seal around the rear of the crank and stops those annoying oil leaks from the back of the engine.

When fitting the kit to the 100/6 or 3000 it can be done with the engine in-situ, just the gearbox, flywheel and back plate must be removed. It requires only four holes to be drilled and tapped in the back of the block. The back plate has to be relieved to clear the housings or alternatively we offer an exchange or aluminium back plate ready machined.

Drilling jig and full instructions are supplied with the kit.

Made in England to our design to exceptional quality. These are CNC machined from a solid aluminium billet with a ground steel friction ring attached to provide the clutch face. The thin ring gear is fitted and grub screwed.

These weigh only 4.6 Kg (10.1lb) complete. So are very suitable for serious fast road and rally cars which wish to use a 9 1/2" organic or paddle clutch. These suit the "Works 8 bolt" or standard 4 bolt crank fixing, or our 12 bolt steel crank fixing.

Should be installed using our flywheel bolts and washers, also a 27mm offset pre-engaged starter motor is recomended.
