So I'm trying to install this pulley (beautifully crafted btw) and it would appear that the inner bore of the pulley is too small.

I used to have the dual belt pulley with the rotor machined on the front and I was easily able to install/remove the stock FD Alt nut (24mm/ 1"). However with this pulley there is no way to get a tool on the nut to tighten it.

I spent some time this morning grinding down a 1" socket even to the point where it broke through the wall in a few places and its still not quite small enough.

I thought about trying the FC alt nut but the shaft is too small. Are you supposed to switch no another nut? (if so that should be included with the pulley)

WTF?

 

Have u try a thin wall socket?

 

Ground a 1" socket down to the point where it broke through the walls and it still didt fit. I them discovered that the nut that was on the old pulley/alt was was not stock. The new fd alt came w/ a 15/16's nut and that socket just Barely fits inside the pulley bore.

 

Yep, it's a 15/16th nut that comes on FD alternators, and that's what you should be using. I have this same pulley on my alt.

 

Or a 24mm Deep socket, trust me it fits slightly better.
