I recently got my Cincinnati Bickford super service drill press out of mothballs and was planning on changing the oil in the upper and lower gearboxes. The drill was obtained, never run, and then was stored for 15 years in non climate controlled conditions. There is surface rust, peeling paint and it looks a little sad. The sight glass on the lower (feed) gearbox showed some sludge like material in the bottom of the case. When I removed the drain plug some water dripped out, then the sludge slowly began to drain (thick black goo). I would appreciate if anyone has a manual and can tell me the oil specs for these gearboxes. I don’t see too much on general searches. It is a big box column with an XY table, 28” swing, 7 1/2 HP. I do plan to flush the transmissions with fuel oil prior to the change. I am afraid there is moisture in both of them after the long sleep.
