Why did they have the two different sized ring gears? It would seem a good move to fit the 3/8 one if you want a light flywheel but then again they would probably wear out quicker :?:

Old Minis were all 1/2". Automatics were 3/8". A 3/8 can be fitted to save weight.
No it won't wear out any quicker, the bendix pinion stuffs one side of it long before either ring gear is worn out! :lol:

Note that Rover etc Minis with the Verto clutch & Lucas pre-engaged starter have a different diameter ring gear. Won't fit early flywheel.

Well I picked up the flywheel from the good doctor today and I've actually had time to look at it and compare it to an existing one...

Gosh! although it's still a heavy pile of metal, lots has been taken off! It even looks bling bling now

Should go pretty good :wink:

Thanks Kev!!!

Graham Russell and I both lighten the 1 piece and 2 piece ones the same way for road use, the material spec of both is good old `grey cast iron'.

The 1 piece finish up slightly lighter.

The 2 piece just has a steel centre hub.
:wink:
