Hey folks, I am trying to solve my 55 272 getting warm at idle and would like to install a smaller diamater pump pulley, earlier on this site it was recommened to get a wpp1 frm cj or a mr gasket 8856 pulley, I got the mr gasket pulley and its for a 3/8 wide belt, I checked on the cj pulley and it is also for a 3/8 wide belt. My engine has a 1/2 in wide belt. Any suggestions?

Ask pulley manufacturers if they have anything close enough to work.
Replace the generator pulley and damper with those for a 3/8" groove.
Have a pulley made. I've had pulleys made by https://www.autospecialties.com/

Maybe check on Ebay or hit up a junkyard? That CJ Pony Parts pulley worked great for me...
Do you have the Napa Thermostat #6? That made all the difference in the world for me.
My 292 ran hot when I got it...I put on the CJ pulley and it cooled down to around 130 or so...I took it apart and low and behold there was no thermostat...I ran a 180* unit and the temp shot up again...220s on the gauge. I ran that Napa #6, which is 170*, and it's perfect now.

Looking thru the Ford parts catalogue, there are at least three single groove pulleys listed for extra cooling purposes for the 1955 Ford V8 engines. They are as follows:
B5A-8509-D, 6.80” O.D., 2.46” deep
B5A-8509-E, 6.30” O.D., 2.46” deep
B5A-8509-F, 6.30” O.D., 2.40” deep
Another option would be to use the 1954-1956 223 six-cylinder w/p pulleys. Two different diameters are listed for those.
EBP-8509-A, 5.86” O.D., 2.01” deep
EBP-8509-B, 5.32” O.D., 2.01” deep
It would be necessary to space the six-cylinder w/p pulleys forward ~7/16” for belt alignment purposes when using them on the Y V8.
While the above part numbers are no longer available, this does show that there are some wrecking yard or swap meet options that will get the job done. Also keep in mind that 5/8” pilot hole w/p pulleys from other cars or applications can be redrilled with the appropriate bolt pattern and used assuming the belt width and outside diameter fits your needs.

Thanks guys I appreciate the feedback, from my research I believe the 55 has a 1/2 wide belt and the 56 has a 3/8 wide belt. I am going to see if I can find pulleys for a 56 and see if they will fit my 55. And I wonder how much they would charge to make a pulley so I will check that out also. Nothing happens fast with this car for sure. THe closest junkyard for what I need is in Tenn. All the old junkyards in LR Ar are gone.

Hey Carl, It would be nice if you had a water pump pulley that required a 1/2 belt
and was in the 5.86 to 6 inch diameter.

My 55 Tbird wp and damper pulleys use a 1/2-inch belt, so does the Powermaster PowerGen alternator for same. RockAuto lists the same belts for 55-57 Tbirds, which vary, depending on the manufacturer, from 0.47-0.53 inches. Based on this information, you shouldn't have difficulty finding a pulley that will accommodate a 1/2-inch wide belt. The Tbird suppliers sell a 1-inch smaller wp pulley that uses a 1/2-inch belt, but expect to spend about $100. It is cast iron/steel, not stamped steel, and it's considerably heavier than the factory pulley, even though it's smaller. The pulley fits all 55-57 Tbirds. Now, the question: Do the 55-57 Tbirds use the same wp pulley as the full-size Fords of the same years?

T-Bird pulleys have less offset than passenger car pulleys, they do not interchange.

I talked with the guys at t bird products and they said the bird pulley wouldnt work. If Carl dosent have anything I think my best option is change to a 57 fairlane pulley set up on the alt and balancer with a 3/8 belt and use the mr g wp pulley I have

I checked and the smallest 1/2" wide pulley is around 61/2 " diameter, Carl

Thanks for looking Carl, unfortunately that is the same size as the pulley I have on the car. It looks like I have 2 options. Get a pulley made or maybe change the alt and dampner pulley out to a 3/8 belt. I just talked to autospecialties and they can make one for about 150 bucks. Thanks for the link Charlie.

What thermostat do you have in it now? If you don't already have it, I HIGHLY recommend that Napa #6 170 degree one I mentioned. That made ALL the difference in the world for me.

I dont know right now whats in the car, I still havent got the fender project finished I am waiting on a parking light housing to get delivered, after that is done I am going to get back on the cooling issue and replace whatever it is with the thermostat you recommend. Do you happen to have the part #

Just like Paul says...that's the goofiest part number I've ever seen and I fully expected the guy at the NAPA counter to treat me like we were at Autozone, but it's a legit part number and made all the difference in the world on my 292.
