SV50 spindles are my lease favorite to do. I don't have prints i can send. I do remember having to change the upper bearing when doing a spindle, so all the motor leads had to be disconnected to get the upper housing out. First one I did took me almost 2 days, but then it was 115deg in the shop those two days. Don't forget the small set screws in the side of the sensor ring. If you try to get it off without loosening them, your hosed. You will need a 29mm socket to remove the coolant coupling. Don't try to work around it, the ceramic chips easy and it 2 grand for a new one.
