Very handy chart, thanks for that. I find it cool that with the box apart I can see exactly how it works and how changing one gear set affects all the ratios.
And thanks Steve, I need to give you a call sometime anyway. I still have your front wing here and some paper for you. I want to try to make this gearbox serviceable if I can. Mainly for the experience. With everything I have done on the car so far just finding a better one seems a bit of a cop out as I have touched everything else. I'd like to have a go at making it work. If it goes wrong I get a better one. And eventually there won't be any better ones so learning how to fix one now might be wise. When I restored my MGB the only thing I didn't touch was the gearbox and it's the thing that went wrong!
I am making progress. I got the bush out without damage. I made this little puller by cutting a piece of steel strap into a rectangle, drilling and tapping an 8mm hole in it then turning it down on the lathe. I had to file a chamfer on one corner so it would tip over but it worked. I used it as a puller with some threaded rod and got the bush out.

The ring was to be used as a spacer. I then had to add a socket to give me more depth to get the bush all the way out.

That worked well and no damage to the bush. Just out of interest what does the Q.88 on the lay shaft mean?
Once I find out if I can get a close ratio set I will decide what to do next but will leave it all apart for now.
