Jay,
How can one tell the bearing type without any disassembly?
Look at the pic Brokenwrench just sent. Note that the
bearing caps have vertical bolts just either side of the oil
cup. That is the cap of a sleeve bearing. If the part with
the oil cup has no bolts and is just a smooth, continuous
part of the casting, that is the place where a Timken outer
race is seated.
Also, how can one determine the machine's age or
production year?
Roughly by serial number, or some machines have a date
scribed into the original Timken bearing races. These are
likely the dates the bearings were received at the Atlas
factory, not the date the lathe was assembled. We have a
serial # to date database somewhere on this site, but not
sure where it is since the move.
