Here is a section view from our offseason project last fall. If you look carefully inside the tube, you can see the space the bearing block has to slide back towards the gearbox and loosen tension (to the right).

Also, here's a view of how we kept the bearing block in place. http://i.imgur.com/VrDEJ.png
It worked, but it really wasn't the greatest method. It should get you thinking though, and we came up with it halfway through building it.
