Everyone enjoying the lovely weather. Been thinking since I had time on hands considering re doing my gearbox and if anyone has recently re done one and if they have a parts list or would it be cheaper and better in the long run to send it in and get the whole engine re done just opinions and help please.

All the major Mini specialists have parts catalogues available, Mini Spares have just updated theirs.

Minispares ans minispeed will do you a gearbox rebuild kit. I'm pretty sure guessworks does one too.

I got mine from minispeed. Scott was very helpful and my gearbox builder was very impressed with the quality of the parts and that everything was covered. I needed a replacement gear and misc bits which guessworks sorted.

Mrpeanut if you dont mind me asking how much did you pay for everything?

[Mrpeanut]

I think the rebuild kit with all bearings, baulk rings, seals, gaskets, diff pin, layshaft etc was £150. The bearings and components were all very good.

I just asked Scott to give me what they would put in a fully rebuilt box. His list was more comprehensive than the others and much cheaper.

Is there a way I could get a hold of said list?

[Fast Ivan]

I've posted a list on your other thread. A rebuild kit is the very basics. As always you won't know what you need until you get it open, inspected and measured.

[Mrpeanut]

Is there a way I could get a hold of said list?

I haven't kept it. Just phone a few suppliers and ask what kit they do or could put together. I'm pretty sure the Minispares site still lists a kit with details of what's in it.

Unless you want to do it yourself, because you want to learn, then you should consider Guessworks (on here). First rate service and quality, good prices too.

Bloody hell, they got expensive !!

I suspect someone will try and supply an £80 gearbox kit, but shafts will be made of rubber and bearings made of cheese...
