Lathe sold for just over $3K. Someone got a lathe that had very little hours on it. Clean up required due to outside storage, hope it works out well for new owners.
 
I doubt they are buying it for themselves. More than likely being bought and sold to one of their world-wide customers. Thanks for the information.

Hi W,

we just got the machine from sierra equipment.
Do you happen do have any mechanical manuals/other documentation you can send on it?
they only had generic fanuc manuals on it and ladder/plc backups, currently repairing all the cut wires from when it was removed.

Any idea how to pull off the back chuck? It is on there pretty solid.
We were trying to remove the back chuck to check the belt condition, and replace if needed.

Thanks,
Matt
 
The rear chuck is bolted on to a back plate adapter. The back plate is bolted directly to the spindle if my memory serves me correct. The chuck could be bolted directly to the spindle like the front chuck is.
 
Thanks Ken,

yeah we had pulled the face bolts and were hammering but it was not budging with reasonable force.
just wanted to make sure no threads or something that might be holding, like L0 spindles, before using too much force.

Thank you for the info ken,
got it off with some more hammering.
actually wasn't that crusty between the faces, but must've been enough to seize it up.

what oil do you run in the headstock? I was thinking maybe light hydraulic like DTE 24?
