Alternator rebuild

[chevywood]

Ok guys, first alternator rebuild and for the most part it has been pretty easy. The one problem that I have is where does the 3rd little plastic washer go. I have 2 under the metal finned piece that the diode connects 2 with the 3 nuts, but I am not for sure we're the 3rd would go

How about a picture of it?

Lets see if this works

 

[doghead]

I meant the washer.

 

[chevywood]

The black ones are the ones that came out, Which they are a little thicker, the white one is the one left. Also, what is the 2 tab metal piece as there was not one that came out

 

[doghead]

The 2 tab thing is a resistor. It is not used in all alternators.

 

[doghead]

So, the white one is the only one you need to know where it goes?

 

[chevywood]

Yes, there were 3 white ones and I have 2 under the big metal piece the diode connects to but don't know where the 3 rd goes

 

[doghead]

Let me look at the -20TM. Off the top of my head, I dont recall for sure.

Could it be the "insulator" shown in that picture, at the top right?

 

[doghead]

Whoops, wrong TM, its in TM 9-2320-289-34.

Viewing with adobe reader, around page 264. Take a look at that.

Off the top of my head, I believe that's an insulator for one of the posts that protrude externally from the case. But I'm not 100% sure.

So where did this third washer come from? Did you remove it from the alternator or was it in a kit?

The TM 9-2320-289-34 tech manual has a step-by-step explaination of how to rebuild the unit. It also shows where all the parts go. As far as the two tabbed resistor, all the Cucv units I have rebuilt used that resistor.

someone may have been inside the unit before you and not replaced everything back where it belongs.

i always like to take pictures of what I am taking apart so I can remember where everything goes.

Thanks, Doghead, got it figured out, I was looking in my manual and couldn't find, went to online library and found your reference

 

[Vhyle]

So what was it?

 

[chevywood]

As warthog said might of happened, I think somebody had been inside of it before me and possibly added a washer as well as not put in the resistor because when I went back and checked mine with the rebuild instructions I had it correct. I was even worried so I took it to oriely's to have it tested and it passed fine.
