Valeo alternator repair part 2 slipring change. 

Here over 11 years later and in my opinion one of the best tutorials great job Martin 👏👏🍻

Great tutorial.Made it a lot easier to repair my alternator.Thanks for sharing.

Another way to un-solder the stator wires from the rectifier bridge's connectors, is to place a little solder resin type acid onto each connector. Heat each one with a 450 watt soldering iron. As the acid melts into the connector, hit it with compressed air to blow away the solder. Repeat if needed. Small side cutters and needle nose pliers used in electronics work, can be used to dislodge and remove each wire and open the pinching leads from the rectifier. This eliminate damage to the stator wires, or re-use the rectifier again. Plus, they will be have some solder on both halves to allow for easier re-soldering. Just use rosin type acid soldering paster for electrical connections, it will boil, bubble and melt once hot enough, then apply solder. Don't forget to pinch the connector around the wires as needed to help complete a good soldered joint, that maybe disturbed by vibration. Just a few things learned after decades of rebuilding parts, when they where not offered. ASE Master Tech since 1978.

Dude, I followed your video instructions step by step and managed to repair my Valeo alternator, no problem. I would like to thank you for taking the time to make this video, you did a great job. The repair process itself is pretty straight forward but you managed to provide the necessary tips and tricks to actually do it through and through. My alternator is silent again.

This was the best tutorial I have seen about the alternator repair. Thanks a lot!

The most detailed video I have seen to date. Excellent job.

What a great video my Partners alternator has just gone with the same problem she get really worried when something goes wrong with her car I took the alternator off and it had this problem the slip ring and brushes had worn out was looking to buy a new alternator but they cost to much so I looked to see if i could buy the slip ring and brushes found the kit on eBay and looked to see if I can find a tutorial on how to replace it you’re video was the first one watched you’re video you explained everything very well and have helped me do this repair just want to say thank you for you’re video and explaining how to solve the problem

Thank you, Martin, I am rebuilding a Denso alternator and have to replace the slip rings. The job is very similar to this one. Your video is very helpful. You have done a great job on the alternator & given me the confidence to replace the slip rings myself, saving buying a completely new alternator.

What a professional work and video! Pure PRO. Thank you.

Great video, currently (get it) I am in the process of 'rebuilding' my Bosch alternator and have found a couple of videos on your channel... all relevant and great pointers and advice..

Ottimo lavoro! Grazie per il tutorial. From Italy.

Excellent vid my man, thank you for the extra knowledge.

Brilliant little tutorial. Would never have even attempted to effect a repair on my broken alternator but saw your 2 vids and gave it a go. Worked a treat! Good work, thanks!

Very impressive, no expensive tools needed and a clearly described procedure that does the job quickly and efficiently saving time and a significant amount of money.

Awesome tutorial Very clear. Your brushes replacement video also is awesome. EXACTLY what I needed to repair my alternator. Thank you so much!!

Thanks man, i hade just replace the brushes and colector to my alternator, all was ok. Thank you

Konkretna pomoc - przy wymianie komutatorka. Dobra robota :)

Excellent work my man! You helped me save my customers money!

Great videos from this guy. Very well done.

Great stuff, this is saving me a lot of money! Ok, it takes a bit of time but it's a good feeling to have done it yourself. Thanks for posting!

2001 audi allroad 2.7 just failed. A $185.00 job just turned into a $45 job. great videos.

молодец даже превода не надо все понятно и грамотно!

Another professional demonstration, good job!

Looks good. I recommend you use a higher quality bearing or pull the seals, clean the old grease and use a high quality moly grease. Those bearings will be noisy in no time. Alternator bearings are subjected to immense heat and electrolysis. With that you will have an A1 top quality rebuild that will last as long as the brushes.

Fantastic training skills, really clear and informative.

Excellent video - very clear information - thank you!

Excellent - thanks for the video. nothing is missing, the complete. I do not think that I will succeed if I try but wonderful to see how you do the job.

Thank for sharing keep on sharing

Found this very therapeutic to watch. I honestly couldn't be arsed to do all this, I'd rather just get a 2nd hand alternator fitted. But I did manage to fit new brushes to mine following the 1st video because I removed my regulator in situ without taking the alternator from the car or messing with the belt. Very good videos, helped a lot!

You're are the best! Thank you!

Excellent work. He makes it look easy

Very nice video part 1 & 2 .I never seen that in 25 years .The solder is maybe not the same meltingpoint as electronic things, but higher. Very fine video !

Thank you so much for taking the time to show us this. Some very valuable knowledge here. It is hard these days to get anyone to actually repair something, they all want to replace the whole component! At our expense of course! Thank you again!

Exceptional! Thank you

That was a great video man :-). I've been having a hard time with this, but this will definitely help out a lot :-). Is changing one off a NipponDenso basically the same way?

Nice work mate, Also I am doing My BMW Valeo Alternator slip ring and Bearings and Brush kit.

Gracias por el tutorial he visto muchos más pero este ha sido el más educativo saludos desde COSTA RICA

Is this guy good or what !!!!!!!!!!!!!!!!!!!!!!!

An excellent video,5 stars.

I am having trouble with the Valeo alternator on my Mercedes. I first replaced the voltage regulator on the original alternator and that did not fix it. I actually had someone do it so did not see if the slip rings were bad. I then got a rebuilt alternator and put it on and I still am not charging. I then had a new voltage regulator put on it and I still am not charging. My car has been down for four weeks now. I do not understand this. I don't know what else to do except try to get my money back and just buy a new one. I have never had this kind of trouble with alternators or volt regs before and I have replaced several over the last five decades. And now the clip on the plug is broken from taking it on and off so many times I will have to try to replace that. Your video on this rebuild is very easy to follow.

Brilliant video, excellent thank you

عمل رائع جداً أ حسنت إنا أعمل بنفس المجال كهربائي سيارات أنا معجب بطريقتك الصحيحة في العمل ليباركك الرب

Excellent video, thank you

Very good explained.Bravo !!!

Foarte bun tutorialul. Succes

Hi Martin, I have been doing my own work on my cars over the years (Not a professional) and on occasion would be without my vehicle for between 1 week and ten day waiting for replacement parts, (Alternator, Starter etc). I always assumed that it was financially not worth repairing such items. THANK YOU, you have opened my eyes, I could have repaired alternator or stater in hours. By the way Kudos on your E-Bay store, excellent availability and advice.. Again Thank You for all your advice here. Tom

Great video!

excellent demonstration

Great videos, thanks

just great!!

Great job

Красавчик.все четко и понятно.

I used to work at the main Valeo factory in Angers, France on the alternator line. They even had small bottles of wine in the drinks machine.

Grand. Great video.

Great video. Just done mine after watching. Didn't go as easy as yours ended up cutting through the old slip rings to free them as no vice available. But once off, the new one fitted perfect. Now just have to put the alternator back together. Its a 90A 14v Valeo

Thanks a lot dear for this very instructive videos.
