Need tips on replacing spindle bearings

 Hello,
Need to replace solid bearings on an old Willard Machine and Tool Co
Lathe.  This is an ancient beast, converted from  line shaft to
electric motor power. I figure I can gain a lot of knowledge and
experience from this restoration project.
                                Thanks

Are these bronze, or babbit.  I am supposing, as you have said
'solid' they are not roller or ball.

Some bearings are split down the middle and have the journal
halves separated by shims.  If there is shim left, then one
can remove some and re-scrape the bearing to be round, to fit
the journal on the spindle.

Other bearings are conical and can be tightened up by snugging
the thrust bearing at the back.

1) What is the specific construction and material of the bearings?

2) What condition are the journals on the spindle?  Are they marked up?

3) Is there any shim under the bearing caps?

4) How is the bearing obviously faulty, ie. excess play, siezed,
   noisy, &tc.

There are many folks here who can offer good advice on re-pouring
babbit bearings, or re-scaping cast iron or bronze ones.
