South bend 9" lathe tear down part 2
Next in line for disassembly is the spindle. At the gear end there is a threaded split collar that retains the spindle and is used to remove end float. It has a set screw that you have to loosen, then you need to know it is threaded or else you will try and pull it off (which you can't). Behind the collar is a fiber washer and a steel washer. Once all of this is removed then you loosen the cap screws (or bolts on some) sqishing the bearings on their shims, and then the only thing holding the spindle in place is the very tightly fitted bull gear and its key. In order to actually pull the spindle out you are either supposed to knock it loose with a deadblow hammer, or use a puller. Having only just purchased this thing I was hesitant to go hitting it with a big hammer, so I rigged up a puller
Basically it is just a length of all-thread with a nut on each end, and a big piece of bronze plumbing fixture over the "big" end of the spindle. Tighten the nuts, and the spindle slowly slides towards the right. Here it is after I moved it past the key and can simply pull it the rest of the way out by hand.
Inside the headstock, centered under the spindle at each end are spring loaded felt oiler pads. You can see here that I have inserted little pieces of stiff wire to hold down the felts as I pull the spindle out. That way they don't get hung up on the spindle, and can be reused.
Once the spindle is all the way out you can see the segmented bearing surfaces, which look like they are in great shape (much to my relief!).
