You only need 4 position index, pump runs and water is sent to the right, pump turns off shuttle falls and partly indexes, 1 hour later pump turns on forcing spool up to the left output location and stays there till the pump turns off again.

If I get a moment I will sketch up a quick paint picture to make it clearer.

thats not going to give you a left/right flow though.. to get that you would need a 2 position index and the angle would be to shallow requiring a huge force to switch it. with 4 positions it will rotate 90 degrees each time the pump starts.
