I am at work and trying to order a new belt for my 66 Charger. They list two pulley sizes, 4 3/4 inches and 5 1/2 inches. Here is a picture of the pump. Does anyone know which size this should be?
Is that the O.D. (outside diameter) or the P.D. (pitch diameter) of the sheave? The pitch diameter is where the belt runs......the difference can be significant.......just thought you might like to know.....I would say 5 1/2. Compare to other pulleys in the picture.
I just measured my 67 and that’s the size, 4 3/4”. You know where I can get a new one? I just mine was a little screwed up.I found a picture of my original belts from when I disassembled the engine. Based upon those it appears to be the smaller 4 3/4 pulley, but I will confirm when I get home.
