Twin-groove fan pulley
Anyone have a '54 twin-groove fan pulley you'd be willing to part with? A while back I bought a "complete" two-groove outfit (crank pulley, long-shaft water pump, fan pulley) for my Hornet A/C installation, but the fan pulley turned out to be the single narrow-groove one.

Park, I had a worse problem when I put a dual voltage electric system {one is isolated} and an AC/heater system I made in my 37. Had a local machine shop make a special shaft for the water pump then DAVE K rebuilt it and same machine shop made me a special 2 belt pully, clearance fore/aft had to be perfect. Cost varies among shops but the cost was very reasonable as either is a very simple job,just need precission lathe which I don't have. BUD0

i have one0

I also have one. Bought it for my 52. Sold my 52. Let me know if you still need one.

BRAIN FART. SORRY. i didnt read the description properly. dont have one! these 65 hour weeks are killing me0

So I'm still in need of one of these critters. Has anyone found an available substitute, for Chevy or whatever? Again, I have the dual crank pulley, just need a proper fan pulley with grooves pretty close together as on the crank pulley.0

Park,
I found one that needed asmall elongation of the bolt holes on a Dodge Dakota V-6 pickup truck. I don't recall what year it was. There are several different ones. I found two trucks side by side different years and the pulleys were different. Time to start climbing around a salvage yard?.
see y'all at Savannah,

Yeah, Dave, I guess it may be time for a little junkyard cruising. BTW, I've got the Diamondbacks on the Hornet now, and they look great. You'll see at Savannah.0

I have a few of these sitting around if you haven't found one yet (everyone of them is a little different though) I think Hudson/AMC just used whatever they could source the particular week the car was built. I have yet to figure out Hudson's official setup though. I have a 55 Hornet with factory air, and it has a single groove water pump pulley, but there is a pulley mounted to the a/c bracket. Maybe they used the dual groove if the car had power steering?

A few years ago, I bought "one" from Jim Harmon. He said he had 3 of them on hand, but all were slightly different. He was nice enough to send me all three, which I then procured the one that would work for me and sent the other two back.
So, even if you find one, it might not be the correct backspacing.
Additionally, I have yet to try this, but a good Hudson source offered me this, and it might be worth a "look-see":

To use the double groove pulley you must install a 1954 water pump with P/S. Dave Kostansek has them. This pump is longer to clear the double pulley and all are the same.

Walt, that's what I was referring to above when I said I had the "long shaft" water pump. Actually I have two of them.
Russell, the long shaft water pump has some leeway with where the pulley and fan blade mounting fixture sits on the shaft. I'm told it's a press fit, and you can move that fixture in or out as needed (within limits, of course) with a puller or a press, depending on which way you want to go. Regarding the different pulleys, one difference is that the '54s have the belt grooves closer together ... only about 5/8" center-to-center on the grooves. '55-'56s had them wider spaced because of a different design on the crank pulley, which resulted in wider spacing of the belt grooves.0 -
One of the three pulleys that Jim had sent me was beyond the scope of the travel of the water pump face plate. Granted, it might not have been a Hudson part, as it was not stamped but with a # and at that time, did not have a Master Parts Catalog. It very well could have been to another brand of automobile, although Jim assured me that it was a Hudson. I have yet to figure out the puzzle of the three different pulleys, although was well aware of the movement available on the water pump face plate.
You have informed me of at least the differences between two of the pumps, which is most appreciated. I'm in the same boat as you, Park, as very soon I will also be looking for the proper dual-groove pulley, as I've already secured an NOS dual groove harmonic balancer. Mine will be for the addition of AC, as opposed to the PS. I've done one of these conversions already on our sedan.0 -
I'm thinking about putting an A/C on my 48. Where does one begin to look for dual harmonic balancer pulleys for a 262? As far that goes, anyone had any luck helping Park with the fan pulley?

The dual crank pulley will fit all Hudson engines from 1940 to 1954. But 1948 up is the best as all you have to do is install the 54 water pump with P/S. Be careful if you move the fan spacer as you will ruin the impeller, if you try to push it on further, it must be supported by the shaft only. If you pull it out further, using a regular pump, not 54, you may not have any shaft to support the pulley or fan blades. Just install the 54 pump that has P/S.

Jason: There a several methods to add aircondtioning to the Hudson engine. One uses existing pulley systems and a single belt. Mr. Bob Johnson of Valley View Texas has put this system into a number of Stepdown Hudsons. You can find his name in he HET membership directory.
Good Luck

Well, I've worked out a solution that doesn't require a twin-groove water pump pulley. I'm going to run one belt from crank to water pump to A/C compressor, and the other from crank to alternator to compressor. I'll have two belts on the A/C, which is the main objective. It turns out I can use the original water pump and pulley ... it lines up fine, though it has the "really wide" belt groove. But since I have them, I'm going to use the '54 pump and single 1/2" groove pulley, which also lines up properly with everything else.0

Like to see a pic of that setup when you are done if you can please.0

So would I, Park. I've done this conversion, but the way I had to go about it, I wouldn't recommend it to anyone. I ended up using the twin-groove balancer and twin-groove water pump pulley. The AC is on the Pass. side and only utilizes one belt, but works well.0 -
51A and Russell, I'll take and post a couple of photos of the job when complete. All is coming along well, and I should have it back together by 5/28. As usual, am doing a couple of other things since I'm in a clean-up-under-the-hood mode. I first said "Dang, the front of that block is filthy dirty in no time," then thought a bit and realized it's been five years since the A/C installation. TFWYHF!0

OK, gang ... here's the A/C mount and belt setup that only requires a double-groove crank pulley. Some may notice I've got the '54 long-shaft water pump and single pulley, which I used because I had them, and it does give me the 1/2" belt groove to match the rest of the rig. But the original water pump and pulley lined up perfectly with the rear groove of the crank pulley, so I could have left them alone. I've been running a 1/2" belt on that original water pump pulley for five years with no problem. BTW, in the photo the alternator pulley is its original 3/8" one. I've swapped it out with one for 1/2" belt.
I prefer the compressor on the left side, which isn't so cluttered with manifolds and such. And I like the alternator up top and compressor below, as it keeps the refrigerant lines more out of sight and more protected from abuse/damage. The big mount plate is one the late Clay Hanna used to sell. It'd be pretty easy to have a metal shop make one. At the bottom it bolts to the two holes originally for the generator bracket. It's just a big flat piece of real estate; you mount what you want where you want. The alternator positioning bracket is one I found on a junkyard "walk the line" search. It came off of some rice-burner.0 -
I like it. Thanks for the photos and info.0

Nice Job Park!
Thanks for sharing the how to and the pictures of this installation.

I like it, too. It's much cleaner-looking than what I had to go through and the single-groove water pump pulley makes it more convenient for those trying to do the conversion. Nice job, Park. A few questions I can think of:
1) Are you still going to run a stock fan? Shroud? Electric Fan on front of the radiator?
2) Does the upper radiator hose wrap around the alternator or go over the top of it?
3) Is this on the convertible?
4) Is it a Twin-H set-up and does the alternator interfere with the front air cleaner?
5) Do the AC lines wrap around behind the engine and enter the firewall on the right side? One nice thing about having the compressor on the right side is it's on the same side as the evaporator and lines can run very cleanly straight back through the firewall.
Thanks for sharing, Park . . . you got me thinking.0 -
Russ ... yes, this installation is on the convertible. I did consider running the refrigerant lines above the front cross-member, over to the right side then back to the firewall, but it's pretty crowded at the rear on the right side, especially with a Twin-H car. And I also wanted to keep those lines away from heat to the extent possible. The engine fan is the original. It and the electric fan shown are what I've been running since the original installation five years ago. Interesting that I've never had to turn the electric fan on, parade traffic and all. The photos below will answer your questions, I think. If any others, give a shout.0

Looks great, Park. Thanks for the info.0

Park,
I agree with everyone else. I just wish I had got down to Rock Hill to see it in person. Maybe I'll get free time soon.
