Can someone please help me install a new fan clutch? Just bought it recently (part# VK-DB-004 , vendor said it's for M103). Finally got time to install it, but it doesn't seem to fit.

Basically when I screw it in, the back would hit the fan pulley, i.e. would latch right onto it. I know that it is suppose to spin freely. So anyway, it would be nice if someone can give a rundown on how to install a new fan clutch.

I took some photos of the old one and the new one attached to the old fan blade.
