OKUMA LB15ii-M Retrofit Turret Clamp questions???

Hello. 

I am retrofitting this OKUMA LB15ii-M  live tooling lathe.  

Does anyone know how the Turret clamp works?? 

To index the turret tool, I have a Servo and works fine….

But I dont understand How the turret Hydraulics works to clamp the turret. 

I already checked all the electrovalves;  tailstock, brake and chuck worked fine. 

I hope someone can help me to understand the turret clamp. 

I don't remember on the Okuma, but the normal setup is a curvic coupling to align the turret. Look at the link for a little more info.

Thanks Scott for yor replay.

In this case it is not a curvic coupling.... The servo moves the plate to the corret tool and it is a Hydraulic clamp.....

Today i checked and my problem was that the Hydraulics hoses were connected wrong...... I fixed the hoses and now it is working as i expected...

I will continue with the retrofit....

Thanks
