I've heard guys succeed with moving it out of the slot and leaving it loose, but never had an update whether the pin might migrate farther around since it is now free floating.

What can sometimes happen is you move the tang too far and it lets the fan stay on under 180° and your thermostat is a little lazy and keeps temps at 185° -- and the fan will always be on trying to fight the thermostat.

I really didn't want to post this ugly photo but it does show the bent tang that allows the center pin to be slightly more counter-clockwise. In this particular case the slots on the pin were originally in a 9:00/3:00 location and you can see a very slight pitch on the pin now.

I'm also wondering if a slot might not be cut with a Dremel tool about half way between the stock slot and the outside of the casting?

See on that model is does look like you could cut another slot in it. On the one I pictured pulled from Summit it didn't look like there was room. Ill have to go out and look at mine personally and see.

I was thinking about buying the shorter version of the HD clutch (cant remember the number), because my fan is like 90% in the shroud all the way around.
