I need to change fan belts on the engine. What size is the large lock nut that holds the hub assembly on? I dont have a wrench big enough so I'll need to go buy one. Looks like its 1½" but need to make sure.

Not familiar with an N6 but couldn't you "fish" the belt around the blades of the fan first then align it on the rest of the pulleys.

I can on the N5. It is tight but have done it several times over the last 20 years..My book is in the service truck but I think I added an inch to the belt length...HTH...Dale
