When you start getting into the bearings in the apron, don't get all hung up on all of the bearing numbers on the existing bearings. Most I replaced with more standard bearings numbers and went with all sealed, not shielded bearings where I could. There is one roller bearing that was a bear getting the outer race out of the housing. Had to go borrow a internal puller from O Riley Auto Supply to pull it out. I would suggest you rebuilding the Bijur oil pump also. Replace the felt and screen. Those parts are readily available on the net. The pump itself is untainable at any cost, unless you get lucky and find a good used one out there. Hopefully, the gearing is in decent shape. L & S parts, I believe, are available from Monarch Machine Tool at gold standard prices. Like me, make your own!
Yeah, I hope your bed is in better shape than mine was. I did regrind ways on mine. And yes, I used Molglice to raise the carriage back up in proper alignment. I presume you found my posts on Practical Machinists on the rebuild I did on my L&S. Doing all of this is not necessary in all cases. And your lathe looks to be in decent shape and probably has very little wear to the ways, if any at all.
