Got a new cooly box, Turns out to fit perfectly in the mini's boot with the case I done above. :gimme:.

Also managed to get my hands on a NOS set of radius arm pins with the metal tubes rather than nylon and rubber covers that will last longer than 3 seconds like the new stuff.

Not a lot has been happening really, been driving it a little bit, went up to castle combe which was a great show once again, only one problem with the ignition switch was a bit temperamental. One I couldn't get any ignition when I stopped of on the way up and then it would randomly miss when driving on the motorway, I managed to just wriggle the wires and it would work again after finding what was causing the problem. I stripped it out tonight and looks like theres just so dirty connection.

Finally got to wash it today after castle combe and getting dusty in the garage and being left in the rain yesterday.

So I did start looking at the gearbox bit's, checking over whats good and bad, I'd thought I had better even after being sent to a gearbox expert.

peel off the new gasket on the speedo drive.

To reveal part of the old one... :highfive:

Diff bush measures 26.24, shafts that go through measure 26.12. clearance should be 1 thou (0.025mm) :thumbsup:

Then the selector forks, The 1st/2nd of them was right on the limit and the 3rd/4th was scrap, luckily I've got a good one from the 3 gearbox I stripped down and will buy a new 1st/2nd as they wear more than the 3rd/4th.

So just need to order bits and then can get cracking with the G/box, Tax runs out on the car the end of the month so will be driving it a bit more if the weathers good and then MOTing it before hand so it's ready for next year ;D

Cheers mate, Yeah the grilles a bit different rather than the usual chrome.

A few things have been done over the past couple of weeks, I took the Mini for an MOT so that it's all ready for next year with the 1293 in it, Only had a few minor issues like the windscreen washer pump wasn't connected and the emissions were 4.57% instead of below 4.5% >_< but that was because it was sitting at the MOT station for a while so I went for a blast and it got it down to 2.8%.

Then I could sort out the gearbox bits, put in a few orders with mini spares. I got both 1st/2nd and 3rd/4th selector forks in the end and bought a new 3.2 crown wheel and pinion. I'm not the happiest with the quality (once again  :lol: ) as you can see from the photos below

This photo was taken through a microscope

Anyway, I cleaned all the gearbox parts ready for assembly.

I Bead blasted these bits, I just need to push out the old diff cover bushes, put new ones in and bore them out ... more on that in a bit.

Today I started building it up. First up was the levers and forks.

Put together the synchro hub, I thought it was going to be a bit awkward to get the springs and ball bearings but was easy to do without the proper tools. 

7hvzX2i.jpg

nm0tsbm.jpg

 

Holding the shaft in a vice, I fitted the split bearing, spring and pins and put the gear on.

vopC5j9.jpg

 

Then put the locking ring in, in went a new baulkring and tapped the top hat bush with a brass drift.

97HpCWj.jpg

 

Then the bigger needle bearing and the 1st gear.

zOuN0Tx.jpg

WnJIpyk.jpg

 

Other split bearing for the 3rd gear and the spring and pin

Then the 3rd gear and locking ring

Baulkring

Then put the springs and ball bearings into the other synchro hub.

Mum then came into the garage at the perfect time to help fit the bearing on to the 1st motion shaft, which I used a large deep socket and pushed it in with the vice with a piece of aluminium on the jaw so I didn't damage it.

epNz2HK.jpg

 

All built up.

7ZgghN2.jpg

 

In went the reverse gear

OgOlvtH.jpg

 

The new bearings don't come with the snap ring on it so used the one off the original.

b6GGxMy.jpg

 

Fitted it into the casing and pushed the bearing in as far and square as possible.

89FzFkM.jpg

 

I made this tool from some scrap aluminium, facing it off, boring it out so it didn't hit on the inner ring and made a cap for the end.

ELuzBwG.jpg

8t3YJxG.jpg

nN1EWsB.jpg

 

So tapped that in and also the first motion shaft.

Oyu3roQ.jpg

 

Then I fitted the centre oil pickup and fitted the laygear.

UzAHMEi.jpg

 

And checked the gap with a feeler gauge, it was all good from the previous build at 4 thou.

Lou47eC.jpg

 

And that's where I left it for this weekend, I need to order a new speedo drive to suit the new diff ratio and find time to bore out the diff bushes. I made a fixture to hold them in the lathe on Friday so it should be pretty simple to core them out when its set up, I've got 10 of them to do.

Great write up and pictures! Gearboxes do look far more intimidating than they really are.

Lovely tools too!

Alex, great work once again. Sorry for not remembering but did you start off with a 998 like mine and if so how is the 1293 in comparison. I have an early MG Metro that’s done 55K and was considering boring it to 1293 and fitting it in my Mini. The other option is to take the 998 to 1097 with a Cooper 998 head machined accordingly. Both will cost around £700 just for the machining but I cannot decide which to go with?

Also do you have your own bead blaster setup?

Cheers mate. Yep had the 998 in and then the 1293 in for 8 miles (due to the gearbox crunching) and now got the 998 back in, From the 8 miles I drove it it was a lot more go-y even compared to the ritz's 998 which is it lot quicker than this one. I would go for the 1293 since you have it already and will cost the same to do. What are you getting for the £700?

 

I have got my own bead blaster but for the aluminium bits above and the carb body I used the one at work which has fine beads in it and has a lot better extraction.

Great work on the gearbox, did you use glass beads to blast the aluminium gearbox parts?
