Make sure the sheaves are clean. Mine tends to get a bit of oil film on them after a while and it wants the occasional wipe down with solvent to fix it.
I'm assuming 3 phase at that power level? Fastest way I know to roast a 3 phase motor is to lose a phase. Would be worth checking the motor starter for burned contacts and if it doesn't have thermal overloads to protect the motor you may want to add that.
if its just a bearing, replace it and...
The plate underneath breaks. Did that to mine. Its a cast iron piece and it just won't suffer too much abuse. The screw isn't the weak point on the South Bend. I have since replaced the plate and it has a shim washer to make the stock tailstock wrench give me a useful lock/unlock range.
Stone off the high spots and re-assemble with appropriate cleaning and new wicks. Sell it to someone who wants a lathe that doesn't need to be supremely accurate and just make sure they understand its an old machine that is not perfect. That one has a little more damage than my 10L, but its...
I've had issues with mine when the chuck needed to be stripped and cleaned. It will seem to tighten up but its actually binding on the crap on the scroll rather than tightening against the workpiece. When you re-assemble, it wants a little bit of oil on the scroll only, just enough to keep the...
My 1957 10L has ball bearings, but not the common ones. They are the wider New Departure ones. You could fit standard ones and add a spacer but at the time I needed bearings I didn't have a running lathe on which to make them. I was able to find direct replacements somewhere on the internet...
I actually use the binding screw on mine as a cross-slide lock. Its helpful when doing interrupted cuts sometimes. I've not used the TA for anything other than tinkering yet. For short tapers, honestly the compound is easier to set up and use. You're just limited to about 2" of travel with it.
The cheap mag back ones are really useful for carriage travel. I use mine in place of a stop.
For centering, I have a different cheap gauge that I rig off the tool holder with a rod and a snug. I'm running a lantern post, so the rod replaces the bolt that clamps tool bits in and the...
Its a very nice package, the tooling and accessories definitely have value. If you were looking to rank a 10L, that would have to be up there on the desirable list. Late production with goodies and 4.5' hard bed is a really nice combo. Honestly if I were you and looking for a lathe upgrade...
This is what I used on mine

That sits between the takeup nut and the rear spindle bearing. I suppose you might get it to work on the other side, between the cone...
I used silicone grease in mine. Not actual SuperLube, but a Napa-branded version of the same thing. I didn't fill the whole thing up either, just gave the bearing surfaces a good heavy smear along with a generous wipe on the spindle itself. Seems to be fine. If it gets stupid on me, I'll just...
