Alternator repair question
 

I have a replacement acdelco alternator in my lt-5.
The original alternator is in box and needs rebuilding.
A local shop said they want 85 bucks unless it's all torn up and it has 90 day warranty.

Rebuilt means various different things. To several it means just fixing broken stuff and leaving the rest if it that is functioning.

I would think I would like the whole thing rebuilt as to prevent future issues.

Thoughts and prices paid and services rendered for those who have had their alternators replaced??? Thanks!

Jim, I paid $90 locally to have my alternator "rebuilt", which included new bearings, but I'm honestly not sure about what else was replaced. I got a year warranty on it too. SO it sounds like you're in the ballpark.

Thanks, they want $85 to rebuild with new brushes and bearings - 3 month warranty

They he said it was like $150 if I wanted it shined up. I asked him the difference as that is almost double the price and he said he makes it look "pretty"

It isn't ugly now and its just going under the plenum. I mean what would be the incentive to pay $150?

Maybe it would help if I knew the parts of an alternator.

If I'm getting new bearings and brushings is that good or do I need to be getting other parts in the rebuild??

Jim,

Typically all that goes bad is the front bearing. A friend of mine put new bearings in mine and freshened up the case last year when I pulled my plenum. The bearings were less than $20 if I remember correctly. At 50K miles the brushes were still good.

If you have a press it is not a difficult job. Have to be careful not to crack the case and "clock" it properly.

Unless you are having it NCRS judged in the very near future I don't think you would need to "pretty it up"

That said about $20 for the parts and an hour of labor, $85 to $90 seems in line.

:cheers:

Mine detonated at about 14,000 miles.

So a new bearing and I should be good to go?

Thanks for everyone's help.

:o not to be spending other people's money, but when I replace mine when I do my next plenum pull ( hopefully before it breaks & leaves me on the side of the road ) I'm buying one of these.

pricey, I know but generally you get what you pay for.

Nice, which model you getting?

Re: Alternator repair question
 

Just be aware those are not "direct fit." They are like the LT1/LT4 alternators so some minor mods will be necessay to make it work on your Z.

I think I'm going rebuild mine for 85 bucks. It only had 14000 miles when it crapped out.

Re: Alternator repair question
 

:o I wasn't aware that they were not direct fit. I ran across this link someplace and kept it. I was going to call them to get the skinny. They also sell everything you need to rebuild your own, see the parts section from the home page. I was thinking that I would go that route if the parts prices were right. Rebuilding these & our starters isn't that hard.

If they had one that would fit without surgery I was just going to get the 140 amp version. I don't have any electrical load that didn't come with the car.
