Throw Back Tuesday - Gearbox removal and clutch change

So about 3 years ago I had a little issue with the gearbox. I have since learned that the Midalnds Gearbox in the mini's aren't the best and that a Getrag swap is a popular upgrade. I've seen some information on swapping to a 6-speed Getrag, which I think is the direction I want to go.

More on it here: https://web.archive.org/web/20150404150529/http://personal.stevens.edu/~jdunn/FixingtheWeakLink.pdf

Anyway heres the link to my other blog on removing the engine out and dismantling the gearbox:
Removing the engine & gearbox
Dismantling the gearbox, removing bearings & gears, re-assembling gearbox

Now I'm not a qualified mechanic, and yes this is a farm yard engineers way of doing things, but apart from the wrong bearing being changed, things went well and its still running now.
When Needs must or rather when you forget something!

So how did I fix it? Well I dropped the gearbox out again and sent it off to a gearbox specialist: Top Gear Transmissions. For about 220 quid they replaced all the bearings for me. Considerable less than if I'd not done the graft myself. Since then its not exhibited any more gearbox bearing issues, but now I believe the synchro between 1st and 2nd isn't very well. All the more reason to swap it over I guess.
