Bergmann Lexus s100

Hi
I am in the process of restoring this juke.I have the manual (German) and translation software but it is still difficult.My current problem. Trying to get the basket to stop in the correct position for record pickup.I have moved pindisk and outer relay pulley into different positions but no real difference.when I get it to stop and activate the platter motor basket is in the wrong position,nearly one slot out.With a different adjustment the basket gets to position and then the basket motor forwards and reverses about one slot via k3.taking the mid position of this rocking motion it looks like the correct position.K3 is a changeover switch,should this make then break or break then make ?
Any help greatly appreciated

Steve.
