Anyone have any info on a 1925ish Otis basement traction , I believe to be a #1 1G unit. Looking for thrust bearing info. (I know bearing are not available) If is definitely different then the 1STR or 1 SWT unit.

Trying to determine what is acceptable shaft movement when changing from uo down (CW to CCW) and if shim can be used to adjust it temporarily till we get a new machine.
