My 1950 Merc wide belt pulley is 5 1/2 in.
It's the same as this.

You can try unbolting the generator fully and refitting it with the belt in place. I have found also that it is sometimes easier to put the belt on one of the water pumps last, it goes over that pulley easier than the generator pulley.

It´s the size of the generator pulley that makes the difference.
Sounds about the same sizes i keep at hand B52 and B53 for the pumps and B35 for separate fans.
