Nice job so far, hope you get good power from it.
Looks like you have a 'basket weave' motor there. Two layers of three coils each?
If so and there were wires connected to terminals X-Y-Z, then they are your three point connection. To change from wye to delta, move the jumper straps like so,
 Z to U
 X to V
 Y to W

I have a few of these basket weave motors. Some are set up for the delta/wye change over (6 wires going to the 6 screws) and some are not (only three leads coming out). I've been through all the connection points and cannot find that elusive three point connection. And to top it off, it is wired two in hand, so that really had me going in circles. I haven't given up searching for it yet, just haven't had time for any RE work lately.
