MG MGB Technical - Crown wheel & pinion BTA 1224 & 5

I have a 3.9 crown wheel and pinion. The C/Wheel has P/No BTA 1224 and the Pinion is P/No BTA 1225. I am told they are for an MGB, preceding BTB 653. Can anyone throw any light on this?

I have a part number for midget 3.9 crown wheel & pinion set as BTA1223, so I would hazard a guess that that's what you have.

I might be interested in taking them off your hands if you want to part with them.

Dave,
The C/Wheel is approx. 165mm in diameter and the Pinion is approx. 155mm long end to end. They are genuine unused MOWOG itemes as you can see from the image.

I was going to put them on e-bay this weekend but i'd be happy to give a Bulletin Board user first refusal. I would want 75 plus postage but to not break the BBS protocol please contact me offline on the mail address shown if you would like them.

regards
Colin

Did you resolve what your CWP was for? Was it early MGB, or Midget? I,m looking for an early B 3.9:1, & would like to know what the part nos are.Same item as MGA 1600 Mk2 I believe.

The 1600 Mk 2 MGA uses a 4.1 ratio
