Mori Seiki SL2 oil leak.

[MTech2]

We have a leak behind the chuck and can't find the source. It does'nt seem to be comming from the clamp cyl. ,or through the feed tube. Any ideas?

It's the chuck actuator. They leak internally then weep between the drawtube and spindle bore, coming out the chuck area. Nothing else up there, spindle is grease pack and shifting is done using electric clutches.
