Sandvik Hydraulic Holder

[jpatry]

How FUBAR is a Sandvik Corochuck 930 that won't tighten?

Is it simply a lack of fluid?

What fluid do these things even take, and what is the procedure for refilling them?

 

The backstory is it was sitting in the tool storage rack unused for quite some time and it is unknown if someone fiddled with it during that time.

What appears to be the fill port is a tamper proof torx, so there should be no good reason to loosen that instead of the 5mm hex that clamps and unclamps.

But my suspicion is that is exactly what happened and fluid was lost.

If someone tightens the locking screw with no tool installed, the holder is ruined.

This can also occur if it is tightened on an undersized tool.

It was left with a cylindrical collet installed, and that collet still slides freely in and out

My Sandvik rep stopped by yesterday and I asked him about this 

He said they can be repaired.
