what size socket do I need to remove pulley from old alternator?

JamesDean · #18 06-21-2013, 11:52 PM

Either 22, 24, or 27mm. I cant recall exactly. I think the smaller alts were 22/24 and the bigger ones were 24/27.

I just picked up the alternator today and 2 gauge wire.....this alternator seems pretty big. 1995 S 600. So this is just a simple unbolt old alternator and put on new one with new wire? I've never done am alternator job before. Do I need to remove anything to get to the alternator? How many bolts are holding it on?

need help connecting wires back to alternator and car. Can I connect the alternator B+ directly to positive battery terminal?

The alternator is held on by two bolts. Loosen the belt up, remove it from the alt..take the two bolts out and bam! free!

The B+ can be connected DIRECTLY to the battery. In fact it should to minimize voltage drop.

Here are pics of my alt/pulley:

Note black pulley IS the m103 pulley whereas the grey pulley is the one that the alt came with..

I'd be cautious taking JD's advice. He's not much of a mechanic. If you'll notice, there's not a single hammer sitting on his work bench!

Mere amateur!

Alternator has been officially upgraded!
high speed aux fans, a/c, window defroster, dvd, 50w hid, 55w halogens.....voltage at 12.9! And with a light load idling in P, voltage at 14.5! I'm satisfied. Thanks JD for the help.

Here is my toolbox.. It comes with a remote control for the door!

Somewhere in there is a hammer!

Currently...this is in there.

Which alternator did you end up with the 143 or the 150?

Is the 12.9 at idle? If you give it a little bit of throttle with that load..what the voltage go to?

Glad to have been able to help! Its a worthwhile upgrade!

I have 120 amp I think.....or whatever is for the '95 S600. Yes, 12.9 with extreme load and if I give it gas it climbs up to 14+. I love it! I did notice that my car seems like it wants to "jump" now if I am at a light, but the idle is at about 5000 rpm, same as before. Also I notinced that I need to start braking sooner

I hope you meant to type 500! Mark

lsmalley · #28 06-23-2013, 09:29 AM

Yes ! 500, not 5000, typo

Hey, since my alternator upgrade, I also noticed that the lights inside my window switches on the center console are a lot warmer. If I dim the lights they aren't as warm. Iud this because of the higher output of the alternator? I haven't had any problems, just noticed them being warmer.
