I've seen even water pumps modified to have ball bearings in the front destroyed by the belt being too tight. The vee shape of the belt means it doesn't have to be tight to drive. The greater the load, the more tension on it and the more it grips.
I have at least 2 inches of free in and out movement of the belt at the RHS of the engine before I feel any tension at all.
Over tightening the belt is probably one of the most common errors made by Model A owners.
There's an idea for a new thread!
Back to the OP's generator not holding adjustment. I have made an arm that goes from the top of the gen to one of the timing cover bolts to secure it.
