Factory AC. Holder for evaporator inside evaporator casing

[Claus S.]

I have just had the AC assembly for my coupe rust welded the evaporator casing, sandblasted, primed and painted.
I am missing the part that holds the evaporator to the casing shown on the picture marked with a red arrow

I just wonder how thick the part is and if it is made of aluminum like it looks like on the picture to the left? Is it more to this part than shows on the picture?
Can i assemble the outer AC assembly without using this part or do i need to have it?
The part i am missing is on the picture to the left and the parts on the pictures to the right is of my AC assembly

Any here that know how many 1964 coupes that came with L76, 4 speed manual and factory air?


I edited the post and added this picture so it is more easy to see which part i mean

243, per Noland's C60 table on page 213.

Claus,
I'm probably wrong here but I thought that was not a sepporate part and supposed to be part of the evaporator shell. In other words attached.

DOM. It is a seperate part fastened with 2 bolts and nuts

Here is a better picture of it

Re: Factory AC. Holder for evaporator inside evaporator casing

Roger, that bracket is welded to the side of the evaporator case. It is not really designed to be a separate part. There are also 2 mounting holes on the other side of the case that you can't see in your picture. If you really want to put this system together correctly, I would consider buying a new evaporator. It will come with the bracket already in place. The evaporator fits tightly into the main case and it is important that bracket be properly aligned to ensure a correct fit. Here is a picture of it showing the location of the bracket:

Good luck. Jim

Re: Factory AC. Holder for evaporator inside evaporator casing

The picture of the evaporator and evaporator housing is not from my car.
It is just me that thought that the way it is mounted together on the picture is the correct way to do it.

Re: Factory AC. Holder for evaporator inside evaporator casing

Jim after you said it it is very obvious how to fasten the evaporator to the lid. I suppose it is fastened with this holes on the evaporator


Here is a picture of the old one i have

That's it, those are the holes through which the bolts go to attach the evaporator to the outer box / housing.

Are you going to be installing a new evaporator? I wasn't sure whether the photo in your first post was your own or just an example picture.

Re: Factory AC. Holder for evaporator inside evaporator casing

I think i will buy a new evaporator since i know nothing about the old one. If i use that i have to pressure test it first.
Also i do not know if there can be a lot of things inside the evaporator that does not belong there

Having said that there is no rattle or sounds of loose parts/things inside of the evaporator i can hear if i turn/shake it.

Re: Factory AC. Holder for evaporator inside evaporator casing

I have searched the internet for pictures of the C60 otion/AC assembly for 1963-1967 Corvettes but there are almost no pictures of the AC assembly
The pictures i have is from other Corvette owners with C60 cars

The picture to the left is the evaporator casing for my car and shows the holes for the metal bar i do not have
Picture to the right is not for my car. Just to show the metal bar attached with 2 bolts and nuts(marked with a red arrow) which i do not have Evaporator casing. Holes for the small metal bar close to the evaporator.jpgEvaporator placed in box using a bracket with arrow pointing to the bracket.jpg
It should not be a problem to make that metal bar if needed

If the metal bar for the evaporator on the picture to the right is not original is there any who have a picture or a link to a picture so i can see how the metal bar is supposed to look like?
Also how the passenger side vent is assembled?

Re: Factory AC. Holder for evaporator inside evaporator casing

I went out in the garage and took out the metal part of the tube that is is fastened with 2 screws on the blower motor housing for the AC blower motor rubber cooling tube
The tube was placed on the rubber tube and just pushed in on the blower motor housing on the car and the 2 screws used to secure it in place was there but as you see on the pictures they did not fasten anything since the metal tube was hanging from the rubber tube.

This must be the wrong part? This can not be the correct tube for the AC blower motor rubber tube? If it is there must be some part of the metal tube missing.

This can not be the correct part?

Claus,

I'm not sure I understand your question. The metal bar is supposed to look just like the examples in the pictures you posted above (post #7). If you buy a new Evaporator configured for a 1964 Corvette, it should have that metal bar already welded to the Evaporator.

Even if the old evaporator passed a pressure test, I would be reluctant to use it. They weren't meant to last 40+ years, and I wouldn't want to take a chance on having to do this job twice.

Probably not a bad idea to pressure test the new replacement Evaporator too, just to be sure.

Re: Factory AC. Holder for evaporator inside evaporator casing

Thanks Scott I see. Well no need for me to worry about that part since it sits on the evaporator.
It reminds me a bit of of AC blower box stud plates and rivets on the picture below

Claus,

That appears to be the right tube, but it looks like the part of the flange with the screw-hole in it has broken off.

The same Tube was used for 1964-1967, it is GM 3000091, item 29 in your 1964 AIM, Section C60, Sheet D5. Mine ('67) has the part number in raised numbers on the outward facing side of the flange, followed by the word "KISIEL".

Re: Factory AC. Holder for evaporator inside evaporator casing

I have been looking all over the net for the metal tube for the AC blower motor rubber cooling tube i have can not be the right part?
