Hi, I'll try to make it short....
Logan 9B. 1950's. Working on a project and noticed some noise/vibration. Went to turn the spindle by hand. It felt almost like it was binding up then letting go, then you'd feel it catch and let go a few times per rotation, then nothing, then come back. Basically an increase in torque needed to turn it, then gone. Perhaps a little noise, but not metal on metal or gritty feeling like metal shavings would be. If you let it sit for a few minutes it would be hard to start by hand then spin more freely.
I cannot discern any lateral play in the spindle.
I took the front bearing cover off and let some light oil try to seep into the bearing. Seemed to help. Let it sit. Put the cover back on. This morning when I woke up the bearings feel totally normal.
So I'm at a loss what's going on here. My first thought is these are perm lubed bearings maybe the lube has broken down over time, gotten hard, and is intermittently rubbing on the rollers. Anyone experience anything like this?
I ordered new bearings from Logan. $220 yikes. Frankly I'm a little hesitant to dig into it for fear of breaking something taking it apart.
