I need a part number for a fan belt for a 5/8 wide belt. 39 48 ford single belt configuration.

Thanks,

jim
 
I think the number I have used is "B54 .. This is from memory which is not getting better with age!! kx
 
It depends on which intake manifold you have.
On my coupe I use a B50
On the 32 I have a B51. The manifold makes the generator sit a bit higher.
 
If you want to measure the length of the belt you need lay electrical tape carefully around the outside of your pulleys. Be careful not to stretch the tape. Then lay it out on a flat surface and measure the length. The B will determine the with and angle. Just my way. I hope this helps.
 
Buy a couple sizes smaller and larger then you think you need. Then bring the unused ones back. It will save running back and forth to the auto store.
 
the b numbers are NAPA. I have a B 59 and it is about 6 -7 '' too large. One more trip.


thanks for all the replies.

Thank you 51.

Thanks to all for the education. As I have gotten older , I don't remember things I should.

Its a little late but I just read the number on the fan belt of my 39 deluxe. Its likely 50 years old but might still be some use. Its a Gates Vulco 643 Made in Canada B4. Thats exactly how it reads off the back of the belt.
 
For fan belts go to Paulbhardware.com They are on Woods Corner rd.
in Lititiz,Pa. They have a section of ceiling about 60 feet by 125 feet
with thousands of belts hanging. There are plain belts, inner cog, outer
cog, cloth covered. The "B' belts have a tapper that matches the 30's
and 40's pulley tapper. They have them all listed on their website. G.MC
