Fastener Frustration

OK. Began with a rookie mistake by losing track of the two alternator pivot bolts on the L28 engine I am re-building.

The problem:
The pivot bracket takes an 8mmx1.25 bolt (both sides), but the alternator pivot holes are 10mm. I can't believe that the 8mm bolts are meant to rattle around in the 10mm holes.

The question:
What am I missing (besides the bolt themselves)? Are the bolts shouldered or is there a sleeve(s) (tho my parts diag. does not indicate either)?

A little help please.

Really? 110 views and no one can tell me about the pivot bolts on the L28 alternator?

I'll admit it was pretty dumb to lose track of them, but isn't that punishment enough?

How about a little charitable help here folks.

Please.

Did you ever hear of a shoulder bolt?
Edit: You asked above if it was a shoulder bolt. Makes too much sense that it isn't. Search MSCdirect.com.

Mr.dumbstone:

Thanks for the reply (however cryptic); I was beginning to think the thread was invisible.

Yeah, I could buy something new to do the job, but I would prefer to know how it was done in the first place.

At the very least, I would then know what I am looking for among my parts.

The other thing is that I'm kinda sure I don't remember any shoulder bolts in the dis-assembly phase.

I know, if I'm so smart, how did I manage to lose them in the first place. I wish I knew. I'm guessing the disconnect came when I painted the pivot block. At any rate, I can't put my greasy fingers on them now, so...

C'mon folks; surely someone out there has removed their alternator before. A little friendly help here would be appreciated.

Looking at your alty, does it have ears that (1) have a raised section on the front face like this pic and (2) what appears to be a bushing sticking out the inside of the rear ear like in the pic?

fairly obvious they are M10 bolts. stick a matchstick in there to get the depth of the hole. add the thickness of the alternator flange and voila you know the length of bolt needed. ain't rocket science son. next time if you get a piece of cardboard and stick the bolts in it with a note as to where they go you won't have that problem
