Double Crank Pulley

If someone needs a double pulley,... Here is a solution. Much cheaper than the factory ones that go for ten times the cost of this one. Here is a picture of a double pulley I made using a small block Chevy aftermarket crank pulley from an early Chevy with the short water pump.. It is reversed. I got it brand new off Ebay for about $20.00. I used a single Hudson pulley that had a chunk broken out of the front flange, so i didn't destroy a good part. I used a small hand grinder to remove the remaining front flange. I didn't worry about balance since it is very close to the crank center. It took a little patience to get the pulley centered, then drilled and tapped three holes for the bolts. Make sure you remove the center before you do the drilling and then use short bolts so they don't interfere with the center that is mounted in rubber. It is a copy of one I have on my 49 that someone else did several years ago, So it's not my idea but works great. The end result is a pulley of greater diameter, therefor will spin the water pump and other accessories faster than the factory double. I found this to be an advantage when I had a single wire alternator. The reason i am doing this one is to speed up a water pump on a 54 Hornet with A/C that only overheats at Idle. This should fix it.

Hope this helps someone,
