Maxima Alternator

[GrimGreg]

So, I had bought an alternator from an 80s VG Maxima last summer, and it just sat there collectiong dust. Today I was doing some other work, and had been having charging issues, which were due to a loose alternator belt. I figured while I was under the hood, I would go ahead and do the swap. It is almost totally a direct swap, just need to remove the serpentine pully on it and put the Pathy V-belt pully on it, which is a single nut. The wiring is the same, so it is "plug-n-play" that way. Bolted it in and tested it, I was charging 13.5V at idle like it should, it hasn't charged over 12.5V in the last 2 years, even when the belt was tight!

 

So you go from a 70 amp to a 90 amp without doing any real modifications! Get out there and do it!

my 110amp quest alt produces 60amps at idle LOL and 110amps at 3500 rpm but a little more work but and i think your old one was only 60 amp

I wouldn't bother going from the 70 to a 90 but the 95 to 97 maxima alternator comes in either a 110 or a 125 amp version, but it may not be a direct bolt in compared to the 80's style. I swapped a 110 amp into my 90 sentra, big difference 60 to 110 amp, all I had to do was make one bracket, change the pulley and the plug.

Did the Maxima swap last year...very easy, only paid 20 bucks for it too.

Had to make a spacer for the pully when I did mine, but mine was out of a 93 Maxima goeing into an 88. Might make a difference Cut down a socket and all is well in the world!

I thought they were 60 too, but the tag had 170 on it, and the Maxima one had 190 on it, so was my assumption it was a 70...

 

Originally I was going to do a Quest unit, but I didn't feel like hastling with the machining work to get it to fit and line up.

i was also under the assumption that the stock unit was 60 amps.

What year max and what year is your pathy?

Goein by his info, his truck be a 1995... Don't know what year alty he used though. There IS a thread somewhere (might even be pinned somewhere ) about the comparable year range with some of the people who did is too cents on the differences they ran into if any...

My swap was easy as well. I made a spacer for the V-pulley so it would align with the rest of the pulleys, and I needed to grind some edges off of the tensioner bracket so it didn't rub on the alternator housing.

 

60A to 90A is a pretty big difference...

I did just like you, bought one had it tested and put it on the shelf. Ben like three months now. I will get it mounted up soon.

I did check, my stock one was 70amp. Maybe 93+ had 70 and 92 and older had 60 .

perhaps I should look at the tag on mine and see.
