I have a 46-111 that sounds like it needs new headstock bearings. I
don't see how the motor pulley comes off. I loosened the set screws but
it's screwed onto the spindle, and I don't see how to keep it from
turning to back the pulley off.

The Delta parts diagram refers to an "Early" model and a later one,
which take different bearings. How can I tell which one I have? I'm
guessing it's the older one, based on the drawing of the tailstock. The
serial number is FL-833.

If anyone has instructions on changing the bearings I appreciate it.


Of course it will be a left-hand thread, but other than that, standard metal
procedures is all I can suggest. WD40 is my flavor of corrosion-breaker.

The note on spindles and bearings is pretty specific. Extended inner races
is one set, flush the other, as I read it. Spindles are of three flavors,
but that's not important unless you're changing them.
