So next I slid the retaining plate to the groove on the end of the layshaft and reverse idler gear shaft. It takes a bit of adjustment to get the plate all lined up.
Once thats all lined up I fitted the main shaft roller bearing retainer and shim. Dont forget the locking washer bits.

I then fitted the pick up pipe into the oil cage thingy and fixed in place with the two bolts.
You can see that I have put the final drive gear nut and washer on in the picture. Dont know what final drive im going to use on this box now as ive found out during this build that this box is the wide ratio one which wasnt fitted to that many minis. (got this box from a metro vanden plas). Not from my mini 998 as i first thought.
Just goes to show if you leave things lying around with no lables.

The last bit to fit is the bearing for the iddler gear. I used the paint stripper again to heat the box and then a suitable sized socket to drift it in.

So there you go one gear box all rebuilt.

Will strip and rebuild the diff next and before fitting, I would be gratefull for any advice as to which final drive would work best on this box.

The eagle eyed techy types amongs you will have noticed that the laygear I have fitted in this build is not the wide ratio one.
Please accept my appologies for this, but i had no idea they were different untill i noticed the grooves in the teeth.
I have ordered a correct wide ratio laygear from guessworks and will change it before proceeding with this build thread.

Err... Umm....If You want to know what happend to the original laygear from this box here it is.

Yep its mullered. By ME being stupid, Will not make that mistake again.

Now that I know about this box I was thinking about fitting it back to its original engine (12h17) which has at present got a standard 998 box under it.

So what do you think for the final drive??
