Leaking Swivel Point on Kitchen Sink Franke Leman LMX651

[searsp]

We have a leak at the swivel point on our kitchen sink. If it helps, the model number of the sink is Franke Leman LMX651 and the Tap Pack has a reference of PWFR0045 (presumably by Franke as well)

There's no screw at the back of the tap holding the spout in place. Nor can you just pull the spout out once unscrewing the skirt/cover. I've even tried rotating the spout both to the 9 o clock and 3 o clock positions (i.e. in line with the taps) and it still won't pull out.

Am getting a tad frustrated as I'm sure this will be a simple job as soon as I can access the O rings, which are 6 years old and probably both in need of replacing. Any tips as to how I can remove the spout would be hugely appreciated!

Many Thanks
