View Full Version : How do you disassemble a Hardinge live center?

Hello all,

I just bought this Hardinge live center and I need to open it up and find out what is going on with the bearings. Replacement perhaps? It's running rough. I've taken apart other live centers but I can't figure out how to get this apart. Any tricks? I assume I can pull the two halves apart but haven't come up with any clever ideas? I just refurbished a Skoda center and I was able to ram it into the tailstock, grip the point in the chuck, and pull it apart by retracting the tailstock. No dice on the Hardinge.

My memory is a little fuzzy, but basically you fabricate a circular clamp to grip the aluminum cone on the front, and press the center out thru it. Once the front cover is off, the rest is straightforward disassembly. I may have made a second clamp to grip just the straight portion of the center where it meets the work. You can also grip that portion in the headstock using a collet.
