Buick GN 87 alternator

I have plan to repair the alternator, which I have in the box in our store. It is the genuine GN 87 120 A alternator CS 144 unit. The broblem is, that I have lost the two spacers/collars, which belongs to the front bearings, before the bearing and after it.

So, where I can find them? If there is not the source to purchase them somewhere, so what is the best choice for an new alternator from RockAuto?

Thanks in forward!

Any alternator/starter repair shops near you?

Thanks for your answer!

Yes, I have shops quite near, about 30 kilometers. I will ask them. But anyway,
I could guess, that they haven´t any parts for AC Delco cs 144 alternator.

If its just spacers/collars then anyone that deals with electric motors or the like should be able to source what you need.

hanks for your advice! Yes , it is the spacers/collars in question. RockAuto has the rectifier in to this alternator and I have the feeling that the old regulator is ok.

IIRC, the front end is just a 203 bearing, and any motor shop should have OR/IR spacers, Belleville and wavy spring washers for those, or they shouldn't even be in business. If there isn't anyone nearby, you could search the web: https://catalog.lesjoforsab.com/ww-39-5x33x0-43x3

Thanks!

I will ask them..

Hi all,

I will ask once again, what is the reasonable good choice for Buick GN 120 A alternator?

What brand, Ac Delco or what and from where?

Tanks forward!!

Hi all,

I found the original collars/spacers in my own store, when going trough the all boxes again, where I have GN parts! I found also the brand new rectifier bridge for the alternator in question.

Thanks for the help for all!
