Will a 3/8" belt work in a 5/8" pulley?
Will a 5/8" belt work in a 3/8" pulley?
Dumb questions, I know, but I'm curious.

I currently have an 8BA Flathead using 3/8" belts/pulleys. I need to rebuild the water pumps, so I'm thinking of beginning to convert the pulleys over to the wide belts. If the pulleys are mismatched for a while, will either belt work?
