I'm going to be setting up a decent little workshop here at home.

It does not look like a normal capacitor that I am used to. It is slightly bulged around the centre of the plastic outer

If the cap is starting to bulge then its probably on its way out, is it domed on the top as well ?

It's a pair of XY suppression caps so not the same as a failing electrolytic that bulges.

So the bulge isn't a bad sign Andy ?

Not in the way it would be with an electrolytic.

I expect it's just the resin case due to heat.

Yeah, that's what I meant. It is not a capacitor that I am used to with a metallic casing with the cross on the end etc. This looks like it has been connected outside of the plastic cylinder and then put together with a filling compound. The is slight bulging around the centre of the plastic cylinder. At least I know it is there. What I will not be sure abut will be how it is all connected should it fail.

I suspect I will be asking questions of Andy again.

It's just connected as loop in and out so in parallel with the supply to the motor.

What is the transparent wire for? I am pretty sure that there is only four wires going into the capacitor.

There should be 5 as your diagram and it should be connected to earth.

One way to see if it's still working OK is to have a radio plugged into the same socket and see if you get interference when you start and stop the motor.

Edit

Just looked back at your photos and it's their just sleeved Green/Yellow as the earth.

Aha. Yes.

Clearing the decks so I can get into my clocks. This is a ship that was my mothers. I have had it for probably 20 years and it looked like this. 

Now it looks like this. In bits, but you should get the idea.
