I swear...if it's not one thing it's another.

Now that I got the correct adjustable generator bracket, I see that the belt is now hitting the bolt.

I'm assuming I have the wrong generator bracket.

put your bolt/nut in the other way..."head" next to belt..

That was the first thing I did was check my assembly manual and I have it bolted on the way it shows in the manual.

I'm thinking it might be the bracket. So I took it off and here is a picture of it.

Did you ever determine if you have a real tach drive generator or a passenger car power steering generator. That will also make a difference.

Can you get your finger between the generator mount on the end plate and the body of the generator?

66jack

How did your belt line up with other pulley's?

can you move the plate to make up any/adjustment/clearance?

Make it where you can drive it and enjoy it. Figure out all the other stuff later.

To answer your questions...

1. I have the correct generator.
2. I cannot fit my finger between the bracket and the generator (another hint)
3. Never had any other pulleys on it. I have the correct pulley.
4. No I cannot move the bracket
5. Can I make my own bracket....sure, but would be nice to know what the correct one should be so don't end up with another problem like not able to close my hood.

You are right, but the AIM is wrong. In production, the bolt was installed with the head on the outside. Try that.

I thought of reversing the bolt, but it still seems close to me. Considering some are suggesting that I should be able to put my finger between the generator and the bracket, makes me think the bracket isn't right. I could easily make a new one if I could verify the dimensions.

Not the bracket..... the generator end frames. They are most likely from a passenger car PS generator.

Did you change out the pulleys yet? They are a major part of the clearance problems you are having.

jusplainwacky

I believe the pulley is correct. Before I put it on, I measured it.
I'll check the generator frame bracket...anyone have a correct one they can post a picture of? I thought mine was correct.
And the pulley wouldn't have anything to do with me being able to stick my finger between the generator and the bracket.
I would think someone on here would have a bracket laying around they could measure. I think that should be the first thing to figure out.

mashinter

Sure do. I get 4.5 and 1.0 just like on your 4-hole bracket sketch.

jusplainwacky

Thanks Bill!! I really thought this bracket wasn't correct...so much for that.

So, is it the generator housing bracket that is incorrect? I'm guessing it much be, cause I can't put my finger between the bracket and the generator and I can't believe the bolt is this close to the fan belt...but maybe I'm wrong. At the very least, I'm turning the bolt around.

jim lockwood

My mistake. After seeing your pictures, I agree.

jusplainwacky

Jim...you saying the brackets are correct?

Frankie the Fink

Here are the differences between the passenger car and corvette generator frame end plates that Jim Lockwood refers to above.

jusplainwacky

Thanks Frank...you posted that information before and I still couldn't tell, but I didn't have the generator out like I do now.
Looks like I have the right brackets.
So if the plate is correct, and the frames are right, why is it that I can't stick my finger between the generator and bracket?

I think your generator end frames are not Corvette, as shown in the doc Frank posted, something is mixed on that unit.

Measure distance from the center of the armature shaft where the pulley is, to the center of the mount sleeve inside the rubber bushings. Remove the tach gearbox, and measure the same from the drive shaft.

I think it's not going to be 3 1/4", which is the Corvette generator spec. Pass car generators(for '58 at least) are 3 1/2".

Or you may have a mongrel, one Corvette end frame, and one non-Corvette end frame. If so, and the drive end(pulley) frame is 3 1/4", and the commutator end(tach gearbox) is 3 1/2", it'll tilt the generator downhill and may cause what you're seeing.

Can you take a picture like this view.....
This one has the tall drive end frame, and the short commutator end frame. This one will point uphill when mounted. I'm wonder if yours is the opposite, so it points "downhill" on the manifold U-mount bracket.

Edit....actually, now that I look at this pic again, i think the one shown here could cause it to be too close to the belt when tilted "uphill" ??? Maybe.

Hey Rich....dang, I just missed your post. I put it back in the car with the bolts facing the opposite direction (as was suggested earlier) and I have plenty of clearance now.

I'm pretty confident that I have the correct end brackets based on Frank's and your pictures. Since I'm leaving it as it is, I really didn't want to pull off the tac-drive...I believe there is a gasket there??

I only have about a 1/4" between the generator and the U-Shape bracket so if I was a 1/4" shorter (passenger car)...I would think it would hit the bracket.

What has thrown me is putting your finger between the generator and the bracket. I can't do that.

jusplainwacky

Ohh...BTW...I did put a level on top of the generator and it's perfectly level.
