Are 22A1288 gearboxes just standard B type boxes or where any factory built with Cooper/S gears in them.

Cheers

PS - I'm not talking about this one on eBay

I've got one here with the close 22G232 ratio gears fitted, looks original factory build without all the usual 'marks' left by rebuilds!
Have a look at Bart's + Nicks PDF.

Thanks for that link Bob.

Looks like I’d better make some further enquiries on that one

Early remote change 10 inch wheel 1275 GT ?

1128 weren't they ?

Should have looked through the list first, 3 synchro vs 4

I also confirm the 22A1288 with the gearset based on the 22G232 laygear.

I've got one on an S lump, I was wondering the same.

Picking up on an old thread here.
Can anyone confirm if a 22A1288 gearbox (with hardy spicer) was ever used in the Mk2 1275 Cooper S from the factory?
Many thanks
Chris

Look at and click onto the reference page given by 1071Bob a couple of entries back. It will tell you all you wish to know.

A fantastic and really useful piece of research

Yes, The 1288 was one of 3 different 3syncro gearbox cases used between 67&68 for the Cooper S. Unfortunately, that list shown previously isn't 100% accurate.

I had one with hardy spicers and close ratio gears. I lent it to someone so he could take the diff and I got an empty case back

It had a “12F” number hand stamped on the side opposite the 22A1288 from memory

Thanks Peter
I have all that information and I'm just trying to find out if anyone else has come across this gearbox fitted in the Mk2 1275 S?
I know of one that 100% has had this gearbox fitted since 18 months old and possibly from the factory?
Of course anything could have happened in this first 18 months.

The answer is yes, with 100% certainty

Thanks everyone.
Does anyone know if/how this can be added to the other information that's been collated?

The difficulty is, there hasn't been any recent publications on these details, and as time passes, new information becomes available, but book revisions take time to catch up.
Another example is. The Mk 2 Cooper S speedos for UK and Canada (and maybe more) are documented as being 4421/36 when fitted with 3.44 FD and close ratio gearsets, but in actuality, many, if not all, were fitted with 4421/32 speedos, Much of this information is based on observation of good original cars, and not yet corrected from previous publications..

Regarding the gearbox detail, the best thing to do is to identify exactly WHO compiled the list and ask him to correct, alter or add to it.

Is he out there somewhere. Or is there some clever computer WhizzKid who could up date it with the fresh info.

I bought my B reg S in 1970 it had one of these a 3 speed it was a gold seal box but was not on hardy spicers instead it was on steel QH joints the engine had Janspeed bits 649 cam etc and the theory some folks had was that the larger steel QH were stronger. Quite harsh but with a 649 hardly noticed.
Cant remember having any trouble with fouling exhaust.

I'm glad that you raised that about the HS and QH UJ's Agricola. I always maintained that uprated QH's - or steel in your case, were as good as HS's. After all, the principle and operation of the HS'd and QH's are exactly the same. But I was too timid to say so!!!!!!!

That doesn't apply to the BMC rubbers though

The only difference that I can see and have maintained since the 70's is that the roller bearing QH's are seated against a tapered semi housing and retained with a yoke (that most OVER tighten and exacerbate the situation). While the roller bearing HS's are within a housing and retained by circlips.

They're both needle rollers, both take exactly the same arcs of movement when you're driving and both are subject to the same(?*) centrifuge forces too.

My S was running on QH's for 7 years or so while I got around to '.....doing something about it one day....'. What I'm saying is that if the only gearbox (or diff) you can get is a QH type, then get it.

& if you can get the steel ones let me know!!
Much easier to fit: the trick was to make sure the ubolt was an easy slide fit in the yoke as they seemed to spread in use if my memory isnt playing tricks?
