I think that one may be a match. I don't understand how to decode the suffix info, but I'll check the cross-ref on this one as well.

Cory - Just got to the shop (after cleaning the gutters on the house 'cause we are supposed to have a DOWNPOUR this afternoon, and then snow tonight/tomorrow) and had a conversation with Clay/82 PIT BULLNOSE on the phone. Turns out that his '82 has a 302 with A/C but he's converting it to a Cummins from a later F850. So he suggested that you contact him re the pulley.

And, he works for Ford and can find PARTS. He has a network and a little black book with PN's and people's names. I'll let him tell us more about what he does/can do, but I think you need to contact him.

And now I'll see what I can find.....

Yep, David. He apparently does that as well.

Ok, on Cory's quest, I did find Page 5 of Section 60 on the 1982 microfiche, as shown below. But, there are no A3A's. Just the info we already had that ID# D3DE 6312-AA is PN D5DZ 6312-A.

Then turning to the cross-ref I do find lots of A3A's, but no D3DE 6312-A3A's.

But, I have come to a conclusion, and let's see if y'all agree with me. At the top of Page 173 of the April 1980 Master Cross Reference List I find this, with extraneous info left out:

Known Part Number Service or Engineering PN
D5UE 6312 AA D5UZ 6A312 A
D5UE 6312 A1A D5UZ 6A312 A
D5UE 6312 A3A D5UZ 6A312 A
. .
. .
. .
. .

D7AE 6312 AA D7AZ 6A312 A
D7AE 6312 A1A D7AZ 6A312 A
D7AE 6312 A2A D7AZ 6A312 A
D7AE 6312 A3A D7AZ 6A312 A

So it looks to me like an engineering # suffix (what's on the part) of AA, or A1A, or A2A, or A3A all cross-ref to the same service part number, which is what we see in the catalog. If I'm right, then the pulley you found is the right one.

Thoughts?

I sent Bill/Numberdummy an email today asking "If an ID/engineering # ends with something like AA, is it true that the same number with A1A or A2A or A3A will cross-reference to the same service part #?" And I got back a one-word answer: "Yes."

So that A3A pulley you found will work. But, the one from Clay may be better - assuming you've contacted him.

Great info Gary, thanks! And yes I did contact Clay. Going to talk today when he gets a look at the part.

That's good info to have on the number suffix.

So I'm off to a good start with the hard parts for this swap.

Thanks for all the help!

Re: Factory AC conversion thoughts?

I was, quite honestly, thrilled to have come to that conclusion and have it confirmed by Bill. I've been puzzled by the suffix variations, so took some time this round to do just a bit of research and it paid off.

When you talk to Clay today you might ask about the other parts you are looking for. He seems to have sources.

That sounds like a Bill answer LOL
Good to hear you kind of talked to him.
He has been MIA over you know where and we are worried as we have not heard from him.

I'd asked how he is doing in my original email, but unless there's some way to interpret "Yes" as being an answer to "How are you doing", he didn't say. So I just tried to call him, but no answer. Now I've responded via email asking the question again. We shall see.

Re: Factory AC conversion thoughts?

Hey Gary,

I seem to recall reading that the passenger side kick panel is different on the trucks with factory AC. Do you know if this is right or wrong?

Gary Lewis

Re: Factory AC conversion thoughts?

Administrator

Yes, there are two different kick panels - those for the A/C trucks and those w/o A/C. See the page here: Documentation/Interior/Kick Panels.

But I like the non-A/C kick panels and if I had them I sure wouldn't change when installing A/C.

Re: Factory AC conversion thoughts?

Thanks Gary, I didn't realize that you had already created a page on the topic.

Ok, I'll try to get a set of these panels as well.

Edit: Right...I just read that you said you wouldn't change them. I was thinking that after the fact...I can just keep the vents closed if need be when using the AC. I guess that's no big deal. Saves me some hassle.

And, when it isn't hot and you don't need the A/C, which may be most of the summer up there, you can just open the vents in the kick panels and have fresh air.

Gary that makes perfect sense. When I went looking for info on the different kick panels, I thought that the ones in the AC cabs had a different purpose and that they would be required for an AC swap. Now that I see they are not required at all and I can get the same effect by just closing the vents, it makes sense to leave them be.

Our hot months here are obviously July and August, and it's not all that uncommon to hit 85-90 degrees, but it is the humidity that is the killer most of the time. It's also warmer in May and September than it used to be too. I guess it's all in what you're used to. A day that I find uncomfortably hot might feel like a cool fall day to Shaun...lol.

I'm hoping the new sliding rear window helps with some air flow on the cooler days when AC isn't needed.

Ha! I actually checked and cleaned them when I had the fenders off this summer. They were surprisingly clean. The truck still only has 40,000 miles on it, and the original owner did keep it in a barn or under a canopy of some sort when he wasn't using it. My wife parks under a tree at the house and I'm constantly digging leaves and twigs out of her cowl vents in the fall.

David,

You're a good man! Thank you sir. I ended up buying these parts and got a little bit of a discount on them. The shipping from North Dakota or wherever they were cost as much as the parts, but I'm OK with that. It looks like everything is there. There is only one part there that I can't identify but I'm sure it will become clear once I have the stuff in front of me. I also ordered a crank pulley with the 3rd sheave for the AC belt. It is coming from North Carolina I believe. That gets me some critical parts for the conversion.

As per Lebaron previously, I will keep my eyes open for a 94-97 AC system and components, but right now a Bullnose V-belt system is going to be easier for me to deal with, even if it isn't as good. I plan on putting a shut off valve on the heater core hose(s) anyway, so I will have control over that.

Excellent! I love it when a plan comes together.

Gary,

I’ve been looking around at AC parts and components and something I’m not finding easily is the heat/AC control panel without the dual fuel tank switch. I know they existed as AC was an option in Flaresides obviously but every time I find a controller or pictures of one it always has the dual tank switch.

Gary Lewis

Re: Factory AC conversion thoughts?

Administrator

Perhaps David can find one? I'm sure he'll be checking in tomorrow.

But, there's another use for that extra switch - a kill switch. Simply wire the tach signal to that switch and ground the other side. With the switch in the "wrong" position no amount of cranking nor jumpering will get the engine to run. The only way it'll run is to flip the switch back or cut the DG/Y wire that goes to the tach after it branches off from the DG/Y wire going from the DS-II module to the coil.
