Fitting a Quaiffe

[MINI-Morgan]

As the title says.... has anyone fitted one themselves?? if so what was involved? What parts did you have to buy? Diff Bearings, shaft seals?

I will be doing this very shortly but I cant find a diagram of the gearbox anywhere! Only the realoem comes close but is no better than BMWs diagram as it doesnt show anything inside the box. Anyone got a better one?

Thanks

If the seals are healthy to begin with, you're careful removing and installing the drive shafts, and wrap the transmission input shaft with tape or plastic, the seals won't need replacing. Here is an overview starting at the top of this page MINI COOPER :: North American Motoring - Clutch, Flywheel, and Quaife Install Overview . Here is another how-to MeV Engineering and Performance

Anyone got the part numbers for the Diff bearings? my local dealer dont seem to have any details for anything inside the gearbox.

Also any of the seal part numbers?

Thanks

to be honest lohe are charging just 300 quid to fit a quaife diff at the moment so it seems mad to do it yourself but thats just my opinion

K-huevo inspired me to fit an ATB diff to my MCS. He's posted all kinds of superb how-tos btw.

It was fun times for me this spring!

SKF tapered roller bearing part #: LM501349

That does not include the outer race that is pressed into the flywheel housing or gearbox housing.

Awesome doing all this yourself mate, and props for finding the time to get hitched while your at it haha!! Congrats

I was thinking about going about the diff route when I had my clutch fitted but it came at such a bad time as my car funds were pretty much dry... I was saving up to do it all at a later date but it bit me about 8 months too early.

So is the OBX like the Quaife?

There's on pressed into the flywheel??

Edit : Or do you mean the cone for the tapered bearing?? When I look up that bearing there seems to 0.7700 or 0.8437inch width...

There's nothing pressed onto the flywheel.

I meant the outer race that the tappered rollers ride on.

Those are the right part numbers. I'll measure my stock diff bearings after work.

Yeah it was a fun experience. My wife doesn't mind me tinkering away in the shop at all.

The OBX is a Quaife knock off. So far the OBX is performing well.

Stock differential bearings have an ID of 1 5/8" and a height of 3/4".

Great! thanks for all your help

A couple of additional questions:

1) What oil for the gearbox??

2) What sealant to use?
