I have been helping a friend of over 50 years catalog and inventory his vast array of Mini parts. Amazing how this stuff accumulates. We found two boxes marked 8G718 Baulk Ring Conversion. They are NOS. We are assuming these would Holy Grail type of parts. He can't remember when or where he got them.
My question is which laygear, reverse gear, and first gear would be used with this set? Also which shift hubs would be used?

Hope there is some info on this conversion somewhere.

Many thanks

Are you in North America? I may be interested in a conversion set if they become available.

Nice find !

The 8G718 is the conversion kit for the Constant Pressure Cone type Gearboxes of the early 850's to Baulk Ring.

These match up with;-

Reverse Gear 22A337
Laygear 22A381
1st / 2nd Gear Hub 22G220
3rd / 4th Gear Hub 22G97

Some additional info from the Factory;-

Reverse gear is 22A377

Typo !

I guessed it was Chris

Thanks for the info guys. Spiders post was especially useful. I realize this conversion set would be useful to someone restoring an early 850 and wants to keep the original numbered case and have a better working gear set inside.

Answer to Tagus, Yes, these will be offered for sale in the near future. You are lucky as we are located in North America, specifically in Seattle Washington. Just down the road from you in B.C. If they ever open the borders! Tons of more parts will be offered also.
