Roll Pin Extractor Tools are widely available -but as i've never got around to buying one i've always used this method:

While beating it out is impossible to avoid I always squeeze a new pin in with a pair of water pump pliers with a new seal then your not stressing the naw seal.

There is a tool that works like a G Clamp to press the pins out and I think they also can be used for getting them in, It is specific for this job on a Mini.

I thought I had a link but can't lay my hands on it. It did pop up on the forum - somewhere !

The problem is most likely not the seal.

 

The way the cases are machined, the shift shaft (which is in a rotating sleeve on the inside) often has too much play, well beyond what the seal - any seal - can take up. The other issue with the comes from pounding the Roll Pin in and out with a hammer and punch, which cam distort the case.

 

Mini Spares have Anti-leak kits for these. Usually they will cure the leak.

 

You can fit the best quality seal available and it will still leak.

 

Try one of these;-

How good are the quick release ones ?

The specialist I sometimes use fit two seals, one behind the other, which helps...

can I put some seal silicone over there ?

As this isn't an SPI / MPI specific issue, I'll move it over to the general PQT area of the forum.

In my opinion the fancy Minispares seal kit is a waste of money, the aluminium spacer doesn't seal anything, all it does is stop the seal being pushed in too far.

 

The best method is installing two seals, even then it will still leak a bit. Just a poor design. Just talking from bitter experience

 

I must say I like that pin removal tool, where does one get such a thing.

It’s not supposed to. It’s to support the shaft and therefore keep it more concentric with the seal.

The selector shaft is already supported by a 2 inch long steel interlock so I fail to see how a 1/4 inch thick aluminium spacer does the trick too. And the O ring on the aluminium spacer - not sure what its purpose is either.

I was hoping to get some photos up today, but,,,,,,

 

Yes, you're right here Rolf that the Selector Shaft is 'supported' in the Interlock Spool however, the machined tunnel in the aluminum casting is pretty poor and cases suffer from wear, so in fact, the Interlock Spool, along with the Selector Shaft end up with considerable play - 1.0 mm isn't out of the question - and it's this play that the Aluminum bush of the Anti-leak kit largely removes as it's housed within the Diff Cap in the same tunnel that the seal is fitted to. Off hand, I'm not sure how much take up the seal will do when the shaft is off centre, but it's not much, around 0.015" at most. Next time you have a seal, before fitting it, slip it over a shaft and push it a little off centre and you'll see that it doesn't need to move far all all before you can see daylight.

 

Probably about 95 times out of 100, they will work, but there's been some cases I've worked on that are too far worn for even these to work. These I've bushed but realistically, it's probably not worth doing ( though, I enjoy getting them 'just so' ) .

I have installed the Minispares kit. My cars already had a spacer in there, though. To replace it you need to install a self tapping screw and pull it out. 

I decided discretion was called for and just put the new rubber in.

Looking on the bright side, the oil leak will provide an element of rustproofing, always welcome on a mini.

The spacer did become 'standard' fit on later 'boxes

I have wondered about this as I have picked up a lot of Gearbox that were Ex-Japan, all late and all have had this in them.

 

Cheers for that.
