Steve - do you think it would be wise to remove the cover and clean out the carbon? This would be on a car that the motor still works but may have a lot of miles. Your looks pretty bad in there and I wonder what cleaning it out would do to the life of the motor. Also can this cover be removed while still attached to the car?

Thanks for all the hard work! I also have your resistor mod in place and it works perfectly!

Best,
Simon

There is at least one source for a rebuilt motor in the US -

The part number looks different than yours.

Steve, is the seal you speak of the black partially melted piece with the silk-screened number on it AES ..... 2018? Or am I missing something?
Simon, cleaning it can only help, but all of that carbon and copper color in the 5th pic tells me it is brush and commutator scrape (between the segments to clean the crap out) time.
Budbundy also showed me a link to a motorcycle ABS motor (same general design, probably identical to ... some ABS model) where the guy tried to do the brushes; fairly tricky getting it apart, drilling though the case, breaking off plastic tabs of brush-holders, etc. So this one is probably doable, but not the best for one's first dc motor rebuild...

Hi,

You'll see that I mentioned them in POST 39 in this thread along with that photo which shows that they damaged the end of the motor when removing the casing too.

No, it's the silicone rubber seal around the black melted bit.

I'm sure that using an airline to blow out all that dust would be beneficial, but it's quite a major job to get the pump removed, only to remove the cover, blow out the dust, and then replace it.

Will do. First I need to take some photos detailing the measurements to be taken to check the solenoid resistance. Whilst the motor and temperature sensor are all that this thread really covers, some quick checks of the other components would be no bad idea to prevent fitting a pump with other issues.

Also I plan to create a thread detailing how to use DIS/GT1 to report accumulator residual pressure. This will be a good test to run if you think your pump may be on the way out as it would be good to know if the accumulator is in good condition before refurbishing a pump using it.

Default Re: M3 SMG pump reconditioning

I posted this in my build thread for my S/C M3 in the F/I section, but here I wanted to share a minor tip to help those with SMG issues or to do some preventive maintenance on their pumps. Thanks OP!!

Here doing some preventive maintenance on the SMG PUMP, I read this part on the forums http://www.m3forum.net/m3forum/showthread.php?t=413137 and has some really great info. After reading this I decided today to do some maintenance and YES! The pump was really dirty on the inside and a lot of dust from the brushes. This is what gets in between the bearings and all other internal parts damaging the SMG PUMP.

I then vacuumed the dust and ckeaned it with electrical spray cleaner

I also cleaned all the internal electrical brushes and conectors as they were filthy and covered in that black dust, all interior parts and came out super clean!

Also, here is a tip... As I was cleaning the pump I noticed the the interior bearing was dry, so I then took a grease gun with a dpecial tip that you can find in any auto parts store. This tip is syringe that is specialized to penetrate in dificult location. Well on this picture below, I was holding the tip really tight against the gap you see here, I also kept squeezing and pressing more greese with my finger. I then kept spinning the bearing and noticed it feeling more resistant with the wheel bearing grease. It was doing it's job. I only have 60k miles, and if this bearing was like this dry, I am for sure that this is the culprit of most failed SMG pumps. This is just a little preventive maintenance. Tested the pump and all worked perfect!

Thanks for posting! In your opinion, is there any chance of removing the pump motor without taking the rest of the hydraulic unit out?

Yes it can be done, it'll be kinda tight but it's doable.
