I bought my 1959 13 X 40 lathe and lubed the cone pulley and back gear ideler with teflon based grease that I got from McMaster Carr using the product numberI found in this forum. My holes state "oil" not "grease".
I am noticing that the left end of the cone pulley starts to get warm after a few minutes running in back gear, the actual spindle bearing blocks remain cool during back gear operation and high speed operation out of back gear. I did not run the lathe with oil in the pulley for any length of time so I have no reference point to use here. I did really load the pulley with a syringe and I can't see that it has pushed any grease out of the cone when I take the gear covers. Spindle bearing reservoirs were flushed and refilled with 100 SSU spindle oil and as stated before, no issues working out of back gear. Before I tear into the spindle any ideas if there any kind of thrust adjustment on the spindle cone that could be causing this or could too much grease actually have done this? Thanks to all for your time.
