View Full Version : How do you remove a live center?

Okay, I have this big Hitachi turning center, and it's got a hydraulic tailstock. The live center's (it's a morse taper 5) bearings died and there's no slot to allow me to drift the thing out. And there's no slide hammer like my other turning center has. That leaves me with having to use a fork, similar to what's used to remove tie rod ends on cars, only those forks are way too small. I've scoured the internet for a tool and have come up empty. Other than making something from scratch, does anyone have any ideas how to get this damn thing out?

Thanks!

Some had a threaded rod through the center of the tailstock. You simply tightened it then gave it a small whack to release the center. Others had a pickle fork like your describing.

This may not apply to your situation, but some tailstock bodies are larger than the quill the they are mounted in. In these cases sometimes you can extend them out, then insert something between the tailstock body and the quill cylinder, then retract it to get it out.

Just a thought,
Joe

Thanks for the replies. Looks like I'll be making my own fork...

Made the fork, hit it with a 10-pound sledgehammer. Did the trick!
