It is kinda suspicious that the noise occurs in whatever gear you
select.? It may be coming from before or after the gear box.? You
might want to check the gears which feed the gearbox from the
spindle and listen carefully to the apron to see if it is coming
from there

I have a 1947 vintage 13 inch SB with the single stumbler
quick change gear box.
I don't use the quick change very often, but today when I
used it, the longitudinal feed seem to work like normal, but the
gears were very noisy.
I would describe the sound as a "rattling".
Before
operation, I did add the Type B oil in of the gits oil caps on
the quick change gear box.
I then tried operating the quick change in several different
feed ranges and the rattling noise was present in all of the
ranges I tried.?
Is this rattling noise indicative of a mechanical problem
developing in the gear box or is it just a lack of lubrication
on the gear teeth face??
If mechanical any ideas as to where to look to diagnose?
If a lubrication issue, should I also be adding lubrication
to the gear faces??If so, what type of lubrication is
recommended?
Thanks.
