Top sprocket nut size

[Pbadgley]

I need to remove the top sprocket in my chain case but don't have a tool to remove it. What size wrench does one heed to loosen the nut so I can remove it?

If I remember correctly it's 36 mm

a big crescent wrench works too

Had to buy extra large crescent wrench to remove that large nut. Just another tool I've added to my collection for future projects.
