REMA 74/E-06010 Motor: Reversing

I've got a REMA 74/E-06010 AC motor that I want to use to test my alternator when I have rebuilt it. Only problem is, it turns the wrong way to make mounting easy, so I'd like to reverse it if possible.

The markings are as follows:

Connector block:

There are six wires coming from the motor: C1, C2, unmarked Brown (assume C3), C4, C5 & C6. The resistances measure as follows:

C1 to C3: 0.1Ω (or perhaps zero)
C2 to C5: 6Ω
C4 to C6: 4Ω

Current connections:
Z: C1, C2
X: C3 (and jumper to V for voltage selection, see image below)
U: Live, C4, C5
V: Neutral, C6 (and jumper to X)

Note also the 220V jumper label:

I"m a bit confused by this, as the main label says it is already 220V, so what is this telling me?

Here is a diagram of the connections:

It looks a real pig to take apart to trace the windings, so any suggestions?

can you see a capacitor inside ?
or only windings?

Like I said, it would be a nightmare to open it.

I decided to experiment, swapping C4 & C6 reverses the direction of rotation.
