I just installed a new A&I water pump on our 1970 3020 diesel. Deere sells either this A&I or a remanufactured one, but no new Deere pumps for this application. This one was cheaper than having my old pump rebuilt by the dealership shop.
Anyway, I assembled everything, and realized the water pump hub protrudes out too far forward, so the pulley will not line up nice with the alternator or crankshaft pulley. I can likely put a pulley with more forward offset on the alternator, but the crankshaft pulley still will be out of alignment. I think I will have to take things apart and have the dealer press the water pump hub on further to correct this.
Take home lesson is this: I will check things over closer before final assembly in the future (I assumed a new part would be assembled correctly...)
Take care,
Lon
