That's called a "One touch collet" that is used to retain/grip either a pneumatic/hydraulic tube.

Measure the diameter of the tube that goes into it & let me know.

I'll see if the ones we have at work are about the same and we'll see what we can do. The ones we have are for 4mm to 12mm tubes.

I can disassemble one of the these to get the "one touch collet" and maybe it'll work.

Man, for some reason this thing never told me this thread was updated. Do you still need that ring? I can look in my stuff later and see if I got it. I apologize for taking so long.

Smile Re: M3 SMG pump reconditioning

Hello everybody, my name is Nick, i am from Greece and i am a M3 owner
Recently i had to replace my clutch in my M3 2006 smg with 130000Km, and i installed a new sachs.
In the way of DIY replace of clutch i thought that i could clean my electric smg pump. And i did it.. I was very nervous, but finally was it a really easy job.
I think that i could share with you my knowledge as you did it to me.
When i open the pump, it was full of black brushes dust. I cleaned it with spray and then i look it inside. My pump was going to be dead soon.
Brushes was good but two bearings and the Commutator was really very bad. So i decided to reconstruction it.
Bearings was easy to replase them, Part Number is 6001, i bought two new skf 6001.
The commutator i took it from a used DSC pump from 2001 M3 E46. First m3 have the dsc pump as external part of the dsc system. So very carefull i uninstall both of them from their motors and put it back to smg.
It was difficult but finally everything worked fine. Commutators have differents but both of them has 12 copper bars.
Next day i visited a torno machine, where i make a plastic ring to fix my new commutator in smg pump axle, then i package it in the axle and solder copper bars with wires. And thats all.
Total cost was 22 euro.
Now my pump hearing nice and smouth.
With Inpa i have check the pressure and i noticed that working between 49 and 67-68 bar. The pump works for 3-4 seconds and it covers 5 gearbox changes Natural - first.
I think that pressure is low but brushes need to apply on commutator, that need to use it for a period and check it again.
Thats all i have to say, thank you everybody.

For those who have done this work. Did you take enough pictures to make a DIY as well as make a complete parts list?

What was the temperature when you measured the pressure? If cold, that pressure is good. With the car properly warmed up you should see nearer 75 bar.

Thank you very much promitheas81 for taking the time to snap pictures and share your experience!
So I assume the brushes where OK, and that its the comutator that wears. Is that correct?
