Hello,
I've recently picked up a 9 inch Logan bench lathe (9B-28-1) and am working through making it usable. It doesn't have any markers of being particularly worn, but it sat for about 15 years before I got it. Before it sat, someone bothered to coat it in grease, which has now hardened to a flaky crust, but all the important bits show no sign of rust or corrosion.
The spindle rotates, and I can't feel any deflection, nor are the measurements significant, but the spindle "settles" into the spot it had been resting in for years. When you spin it a few times by hand, you can't feel the bump or sticking, but it does feel a bit like you have to move some hardened grease out of the way to get it going. I use a Logan at work and it has a smooth action when you turn the spindle by hand.
Considering this is a Logan, with the specially pre-loaded bearing, I'd like to salvage it if possible, as I can't afford the cost of a new bearing.
Is it possible to clean and regrease these bearings? If I remove the shield to do so, do I risk much harm by putting the bearing back into the machine without it? It's fairly well tucked into the headstock casting. Am I evaluating it incorrectly in the first place? I didn't want to run it with the hopes of warming it up and moving some of the grease around, in case it really was dried out and I was going to damage the bearing more.
Edit: I just realized this might not be acceptable content for this subforum, but I'm not sure where would be more appropriate.
