ULTRALIGHT STEEL FLYWHEEL PRE-ENGAGED STARTER

Ultra light billet EN8 steel race flywheelfor diaphragm clutch [NOT Verto] with ring gear for pre-engaged starter.

The latest refinement of the Ultra-light Mini flywheel is that it is now made symmetrically to reduce harmonics vibrations caused by earlier versions identified by their large 3 slots, rather than the current 6 smaller slots- yet it still weighs just over 3.66kg (8.07lbs). This is considerably lighter than a safely lightened standard iron flywheel, and also provides a much hardier clutch surface..



Not recommended for road use. (See C-AEG420)

Flywheel - Pre-Verto Types


The early spring-type clutch flywheels are of no use except where total originality is required on a concours car. The taper is too small and diaphragm pressure ring non-existent. No use to man nor beast. Part No Applications: C-AEG421, C-AEG420, C-AEG619, C-AEG620, 2A3657, 2A3658, 2A3659, 2A3512 With the exception of the fact the two-piece flywheel is two pieces bolted together - this and the later one-piece cast item can be treated as the same thing. They will universally fit all transverse engine cranks from 1964 onwards, so that should be easy enough. If all you can get is the hulking great 1300 type, then this too is as universal to fit, but I highly recommend you get that extra cast lump machined off of the outer edge as a bare minimum. Further lightening of these cast flywheels is possible by having metal machined off of the diaphragm side, from the outer edge of the diaphragm pressure ring outwards.

C-AEG620 Ultra-light steel flywheel (pre-engaged starter type)Fitting instructions


This flywheel is not balanced so should be before use, along with the prospective clutch assembly.

Before fitting the Mini Spares Ultra-light steel flywheel, carefully examine the crankshaft taper for any burrs or other protrusions caused by fret-welding of previous flywheels. All protrusions of any sort must be removed as they will cause incorrect seating of the flywheel which could, in turn, cause this fret-welding to occur and permanently damage both crankshaft and flywheel. A recognised method of ensuring correct fit is to use fine valve lapping paste to lap the flywheel on to the taper.

A good, correct fit will be confirmed by seeing an even grey finish over the whole of the taper on both components. The paste should then be thoroughly washed off using a strong cleaning solvent (such as cellulose thinners or brake cleaner).
