46" mower deck part swap
I have 46" deck on a 318, which has nice bearings and gauge wheels but the deck itself is rusted through.
Another 46" deck from a 316 has no rust at all, just a lot of cracks in all the usual places.
Was going to do a part swap, but unfortunately the bearing hubs are not the same between the decks, as the deck from the 318 has the pulleys sitting closer to the deck surface. Half an inch maybe.
The bearing hubs have the same mounting flange, the pulley on the deck is skinnier, and the hubs have slotted openings to slide the bolt in from the side.
The 316 deck bearing hubs have square openings for the carriage bolts. The bolts can only come out if I remove the pulley.
I can see a variety on how these hubs were made for how the bolt goes in, but what I don't understand is why there is a significant difference between flange and center line of the pulley.
Looking for some ideas or suggestions.

The difference is in the pulleys, not the hubs. Usually, the 50 decks have the belt running a little higher. The center pulley is made to run the belt at a particular height. The outer pulleys have different offsets, so belt height on the outer hubs is just the way the pulley is flipped.
