Hi All,
I just joined this site about week or so ago. I have read all the post to this thread & would like to answer a couple of questions raised. First is I don't think my kit is the only way to do it. I also did not say Dan's pulley was to heavy, just heavy. The keyway is not a bad idea, but in my opinon not nessuary. I have sold about 600 kits & as yet have not heard of any crank bolts coming loose.
My first pulleys were steel as that was all I could find at the time. A customer found the 3 1/2" aluminum one I used next. I got with the pulley company & asked if they would make one to my specs. We worked out a deal & after a few thousand dollars I got the first order of the pulley I use in my kit now. The 3 rib serpentine belt is about the width as a V-belt & has more contact area so the belt tension does not have to be as much as a V-belt.
An as to Dan's question of me not being to smart by taking a 4 rib belt & cutting it down to 3 ribs. Gates does not make a 3 rib belt in the length I wanted. I contacted one of their tech guys & asked about cutting off a rib & was told it would NOT compromise the belt in any way other than being narrower. He said they do the same thing only a bigger scale.
Fisty-1, The pulley you posted a picture of is the one you got though Bill I think. I don't think you can have a keyway cut in it because the part that sticks into the crankshaft is to short to inguage the key. I do not supply a 4" pulley, I said I could get one. The pulleys cost me about $70.00 & would have to have a spacer/bushing made to work. I also do not think I'm God.
Countryboy, You have machined up a very good looking pulley.
Please excuse my spelling & grammer cuse as Dan says I'm not to smart.
