AC blower motor and fan C2

[Claus S.]

The old blower motor and fan is still on the car so i have to ask about the blower motor and fan for a factory AC 1964 coupe
I suppose there is no difference on the blower motor and fan for AC and no AC cars?

When i tried to assemble the fan to the AC blower motor there is a set screw on the shaft on the blower motor

Am i supposed to fasten the fan using the set screw? If i just use the nut that sit on the shaft on the blower motor the fan is loose(i can move it up and down)

Am i supposed to place the fan inside the blower motor fan case so the fan sits correct, then tighten the set screw on the shaft for so to tighten the nut that holds the fan to the blower motor?
If it is so i am a little worried that the set screw will come loose over time
Or is something supposed to sit between the blower motor and fan so the nut at the end of the shaft secures everything?

Have a look at the pictures to see what i mean

Claus -- AFAIK the blower motors are different for A/C cars and non-air. The stamped part # on my early '65 air car is 5044559, and on my non-air is 5044555. I examined a spare "559" I have and the shaft has a "flat" on one side that matches the hole in the fan hub. No set screw. I can take pictures. My fan cage does look like yours, but I don't have a non-air handy to compare.

Hi Wayne
It is great if you can take a picture and post it I was thinking that it might be a spacer on the shaft from the blower motor and the fan?

I just checked my order again to make sure i got the correct blower motor and so i did(part #37-31B heather blower motor(AC)(no fan)Bought from Long Island Corvette
But the fan came with a set screw to lock the fan on the blower motor shaft
I also checked the fan as well and that is also the correct part #37-32A blower fan-metal(the fan is from Long Island Corvette as well)
I wonder if this blower motor is used for non AC cars as well since it came with a rubber plug to put on where the cooler tube goes on the blower motor

On the insulation kit for the outer AC assembly i have 2 rubber seals that is to thick and do not fit.
One rubber seal is supposed to be placed between the evaporator case and the outer AC box. The other seal is to be put between the blower motor and the blower motor fan case
The rubber seals is the same as is used on the backside of the outer blower box on a non AC car and they do not fit a factory AC car

Claus --- will attach 3 or more pics tomorrow morning. I think I'm in the GMT+7 time zone here .

Re: AC blower motor and fan C2

here's a close-up of the shaft with the "flat". More to follow tomorrow. If you push/pull on the shaft there's about 1/2 mm max. play.

Re: AC blower motor and fan C2

Claus -- here's 4 more thumbnails plus a big one (off my original C60 blower on early '65) The smeared yellow ink stamping reads "8 - 64", although hard to visualize without a few stiff shots of bourbon.

The others are: Delco stamping of my original; both sides of my eBay "spare" 5044559, that had been sprayed liberally with full gloss by a previous owner; one close-up shot of C60 blower.JPG5044559-a.JPGthe shaft hole on 5044559-b.JPG the fan cage5044559-c.JPG; notice the "flat" that matches to the motor shaft. What I find fascinating is the "stop" at the end of the machined shaft "flat". I have no idea how they would have machined this feature into the bore.

Re: AC blower motor and fan C2

Thanks for posting the pictures Wayne
I have the original C60 blower motor and fan(it is on the car)but i have a noise in a bearing on the original blower motor(do not know any that restore it)so that is why i bought a new one.
Wayne, you can arrange the pictures yourself by moving the text above or under the pictures
I have the outer AC box in parts and newly restored and when i am trying to fit the rubber seal between the blower motor and blower motor fan case the rubber seal is to big and to thick
I think this is the rubber seal used on the inside on the heather box for non AC cars.
Any here that knows how the seals are supposed to look like?(i have a De Luxe seal kit for the outer AC box but)
Everything in the seal kit fits perfect except the seal between the blower motor and blower motor fan case and between the blower motor fan case and the firewall AC box?
To me the blower motor looks and fit perfect on the blower motor casing without any seal so perhaps it is supposed not to be a seal on the blower motor?

The rubber seal "H" marked with a blue arrow is the one i think can not be used for factory AC cars(i have only seen it on non AC cars)

Wayne -

I usually hit "Enter" 3 or 4 times after the last word in my text before doing the "Manage Attachments" thing to load thumbnails - that way the photos are always below the last line of text.

Re: AC blower motor and fan C2

Since i have the original C60 blower motor how can i restore it?
I have a bearing noise in the blower motor so that is why i bought an new blower motor. Bought the fan as well to in case the old fan do not fit the new blower motor

Re: AC blower motor and fan C2

Can any here that have a 1964 factory AC car post a picture of the location of the horn relay and voltage regulator?
I have seen it on the radiator support and also on the left side inner fender

Re: AC blower motor and fan C2

Claus, my 1964 AC Coupe had them on the drivers side radiator support. Vin 8477.

Re: AC blower motor and fan C2

I think i found a picture. Is this correct? The voltage regulator on the inner fender and the horn relay on the radiator support?

[Dan H.]

Re: AC blower motor and fan C2

Claus, mine had the VR under the horn relay, single hole on top with capaciter. Does your radiator support have the holes below the horn relay or has it been changed in the past?

[Claus S.]

Re: AC blower motor and fan C2

The picture i posted is a picture i found searching the net
On my car both the VR and horn relay are located on the left side radiator support so i suppose that is the correct location for it?

But i have found some pictures and the VR is located on the inner fender and the horn relay on the radiator support

[Dan H.]

Re: AC blower motor and fan C2

I'd leave them as they are on the radiator support.
