Have anyone experience with coolant leak from turrets center part, which should "direct" coolant to one tool?

Now it leaks so that when coolant is on, coolant is coming out of all tools around turret.

Turret center is stationary and turret rotate around that, but there's nothing gasket between those parts and so the coolant goes everywhere. Maybe there's been O-ring or something, but obviously it's not durable there.

We have new 700M and I checked it's part catalog and on that newer machine problem seems to repaired. At the center part, theres spring, O-ring and somekind plastic part, which seal those two part together.

Is there anyone who is repaired that problem with older puma 600/700?
