During pandemic I bought a few "new" machine tools, including 1997 Bridgeport TC22. I was hoping to tap into some other owners here as I dig through it. I've been slowly working through servicing it and getting it running. Although "fully running", it is an old machine and a number of little things have needed attention before I start running parts on it. Lots of cleaning ancient crud... replacing o-rings and seals.
I decided I should likely change the gearbox oil as it looked a little low on the sight glass. When I drained it, only about 3/4 of a quart came out. Post draining the sight glass was the same level... ie it was likely lower than it looked. There is a fair bit of red goo around the shot pin actuator (ie it seems to be leaking there). It also looks a bit wet around the base of the motor. The "cavity" around the main spindle belt was certainly filled with a lot of goo. Makes me think the lower seal on the gearbox is likely leaking.
Was wondering if folks had any suggestions. I was hoping to NOT have to pull the motor/gearbox... but maybe it is inevitable at this point. Does anyone know offhand about how much gearbox oil these are supposed to take?
I'll likely have more questions! The list of things I've already done is long, although I feel like I am getting close to chip time!
