Re: lubricating the quick change on a single tumbler 13 inch

???? if it's any thing like the 9A gear box it counts on the oil traveling through it's reservoir & going through the casting oil passage's & the finally to the oil wicks in the gear box that lube the shafts & gears . I can't say I remember seeing anything when i had mine apart that actually got oil to the gear teeth . These machines were a lot like Harley & other early motorcycles in that they operated on z total loss oil system . Ya just keep feedin oil to it to make it last . I usually fill my gearbox oil cup before I use the lathe & then top it off as I use it . On my older lathe which was a change gear lathe so all the gears were exposed except tor the apron I used " open gear lube " from a spray can from NAPA . this is some pretty sticky stuff & clung to the gears , but also helped airborne crap from hanging out there too . DO ya by chance have a copy of the rebuild book ? if not I recommend it , it also comes with a felt kit which if ya don't know th history of yer machine it is probably a real good idea to at least pull the spindle to check/replace the spindle wicks? before any damage shows up .

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.
