can't remember which dealer classic or ricks etc... that I saw offered fan clutches with different lenght shafts? or did I dream it all? I need to get my fan deeper into the shroud by at least a half an inch to an inch
I don't know about the fan shaft itself but I have seen spacers that sit between the pulley face and the shaft itself to space out the fan somewhat. Most that I recall were made from aluminim and I'm sure could be easily cut down down to any given thickness for a specific application. Seems to me maybe Moroso or Mr. Gasket was the brand on the packaging but its been a while since I have seen any around.
Google something or check out Jegs or Summit and see what you come up with... It really wouldn't be very hard to make something up for a .5"- 1.0" thick spacer from round bar stock that matches the flange diameter of the original shaft. Then just measure the bolt pattern and drill a set of holes accurately and get some longer bolts you're all set - Randy
