Lucked out, just found a parts manual. Just as I thought, bushings and bearings show individually...
I can't think of any way they could have fused together!
Other than making great enchiladas, I do get my hands greasy in my garage shop. Semi-retired now after some 40 years in manufacturing engineering in the Us and in Mexico.
Don't know what happened, but suddenly the cross slide bombed out on me, can't read the dial indicator for precision thread cutting nor measuring cuts to be made. https://www3.mydocsonline.com/pub/Waynelund/DSCF0019.JPG]
Seems as though the shaft driving the nut is frozen.
Any help, or lead...
