Fan nut size

[Bob V]

I built a air chisel style fan nut wrench for my 6.0 powerstroke and need to make a wrench end that will work on the 5.9 Cummins. I think it 36mm IIRC. Can anyone verify the size for me please.

I think it is 36mm. I'm getting ready to change mine too. Tool is nicely done.

Genos sells them for i think 30 Bucks.

Just got in from changing the fan clutch. Not a bad job, the shroud/ boot is tight, and I scuffed a fin, but it wasn't bad. I bought a Lisle tool that included a double end wrench and 2 spud wrenches that hook the fan pulley. It was cheap and effective.
