Cool video but I would offer one recommendation. When cleaning the stator core iron laminations always run your cleaning tool parallel to the laminations. If you run the tool across the laminations and accidentally smear some metal across the laminations you will short the laminations together potentially creating a hot spot in the core.

Good work. I did something very similar with mine. Just a note, the mounting point where it's connected to the engine bracket is actually a negative terminal, so you may want to sand off the paint from there. Otherwise, it will give negative through the bolts, which is not always good.

I came here to study rebuilding an alternator for my Dodge Ram 1500 work truck. While I can afford a new one, I just knew there was a more affordable way cost wise; not sure if it’s more efficient time-wise. Nonetheless, I think I will buy the new alternator, and learn to rebuild the old one using this video and others. I’m even considering pulling the new one after the rebuild, and just use the new one as a backup. This was a satisfying watch start to finish. I think the only skill I like at this point is soldering which I can acquire with some training as well. Lastly, I’d need to acquire a few of the tools he used that I don’t have, but most everything else is covered.

Looks really smart... there is a positive terminal, how does the alternator ground to the battery? Generally through the engine block via the alternator mount then the earth strap. Here it has to go through a layer of nice orange paint. ie) mask the mounting faces before painting if you want the alternator to work.

Alternator Story Time: Had a 1986 Pontiac Firebird once. One evening going down the highway, the faster I went, the brighter the lights became. I limped the car home, going slow, as to not burn everything up. I took the alternator out, replaced the voltage regulator and the same thing happened? NAPA said the "new" voltage regulator I just bought from them was bad 🤔 so I purchased another voltage regulator. The alternator worked just fine after that. Definitely time consuming doing the repair twice!

Yes 100%. It is worth an attempt at repair for original parts because you know it worked at one point. The new parts you have no idea if they work or if they are going to go bad in 500 miles because manufacturing tolerances have gone out of whack these past few years. I also don’t want to wait months on a new OEM part. The 1 or 2 days this takes to do, to me at least, is worth it to avoid waiting 4 months on a $300 part.

This particular brand of altenator (Mitsubishi) is a very common system used by many manufacturers like Suzuki, Honda, Mitsubishi, Mazda, etc. with different regulators, communication protocols and mounting ears , and it can have four main weakness: regulator, stator, rotor, and contact points. Regulators: all D-P pin marked regulators (com. protocol introduced by Mazda in the very early times) with the three pin layout connector are sensitive, and commonly die if the brushes making arcs, because of the wear and grooves of the sliprings. It's the same with the honda three pin connector C communication protocol regulators. The toyota type two by two pin connector regulators with P-D or C data communication and all other regulators with lamp outlet are very reliable and mostly survive the harsh conditions like induction and high voltage peaks from the slipring sparks. Stator: They use a special thin surface impregnation (black epoxy) on the stator dynamo plates, instead of insulating sheets. 1 of three of this altenators need a stator rewinding, because, as the plates corrode, they expand and getting closer to the winding loops at the edges and making a ground short circuit. Faulty, expanded, corroded stators are valuable, because there are no other good alternative for them to replace. Chineese, aftermarket stators has very bad quality, low quality copper and non ferromagnetic steel plates which gets them overheated and burnt all the time. The factory stators can be burnt out, cooled down on a supporting cylinder, corrected on the lathe and rewinded by specialist using insulating sheets inserted into the grooves. Rotor: the slipring-brush pairment is overall optimal on this altenator system, so sliprings often need just to be turned and polished on the lathe to remove the grooves. But, as the sliprings are bigger diameter then usual, they have a higher tangetial velocity so even small grooves on the sliprings can lead into brush sparking and popping, and that small thing makes the altenator bad. Always check brush twisted connecting wire for fatigue. In 1 out of 10 altenators the rotor coil outlet wires around the slipring soldering or inside the insulator tube corrode (green corrosion product is visible) and the rotor coil gets a wire break, which is often invisible, because it can happen inside the coil too. First case can be easely repaired if there is enough wire lenght left to make an extension. Always use FBS glue fillout to take off the centrifugal loads from the the soldered connection. Contact points: Inside the altenator the negative power diode bridge and the ground point of the regulator are making the ground contact directly through the internal aluminia surface of the back case. This promotes the contact corrosion of the backcase and it leads into regulator malfuncion and high internal voltage drop (low voltage charge output on the vehicles grid), so in mani cases the altenator needs to be cleaned at this contact surfaces to resurrect. Older Mazdas have the windscreen washer fluid filling hole near the altenator connector, so small leaks slowly corrode the altenator connector wires. My opinion on the video: rust removal and painting the stator is necessary to prevent the corrosion and expansion, but painting the inside oft the back cover is a mistake, and the ground contact surfaces will never make contact again.

Over here, the alternator is changed due to diminished carbon brush. Very rare case for the bearing to spoiled first than the carbon brush.

You can pry and tap the rear housing and stator assembly first before you remove the pulley, this way you can hold the rotor and rattle off the pulley and you wont need a puller to remove the rotor from the rear housing. I would have replaced that slip ring instead of machining it unless you had a spare rotor, also get a bigger soldering iron. Even now i come across units that i rebuilt 15+ years ago i can tell they're mine because of the colour i would paint the stator, there will no mistaking your work in the future. Good job👍

@@cephasgunn1993 it will all add up you'll see, you dont need to go mad spending neither, buy as you need or as job requires. And even cheaper tools will last you forever since you wont be taxing them every day all day long. I have some tools that are over 15yrs old and they are still in great/like new condition and it feels good to use them again and again. If you have interest in cars or general diy and you know you will be doing it then its good to have tools. I am at stage now where I can maintain all our vehicles incl my job van and it feels great to be honest. Of course if you can afford it go for a better equipment, but my point is you wont need top of the range latest pro tools. When it comes to sockets I would highly recommend quality impact set rather than cv if you use impact gun, which again can be gotten cheap enough.

My grandfather used to work at a gas station/auto repair shop back in the 70’s. He said when someone drove in with a bad alternator, they’d tell the customer “No problem! I’ll get you a new one. Be back in 30 minutes.” They’d take the bad one out back into the shop, disassemble it, clean it up like this video, and paint it with silver rally wheel paint to make it look brand new. 15 minutes to take it apart, clean it, and spray it after making sure it works. 15 minutes for the paint to dry. They’d come out to the customer with the old alternator and sell it as a brand new one. That’s one of the ways the shop made extra money.

Love it! Came out super clean. One question: Did you not use any anti-seize or dielectric grease when re-assembling? If you go through all of that trouble restoring it, would you not want to prevent future seizes and hiccups? Swapped the alternator on my 1989 Toyota Celica couple of years after I got it. Looked half decent but didn't work. Got a new one for 200 euros. If that one ever fails I might try this instead.

Nice, just ordered my parts for my original Honda alternator. an aftermarket one i have on now works but gives a dashboard light so i'm going to try replacing the bearings and brushes on mine, it did still charge just rattle. Seeing an alternator being painted here never crossed my mind, it looks nice, might try it. replacing some parts comes out insanely much cheaper than getting a new one. the difference is 20€ vs around 1000€ excluding labour of course.
