KV where did you get the seals for the spindle shaft .I may need to replace a slow leaker and have been looking i have the same lathe as yours.Here is the page for parts that should fit. Like has been said many were just variations. So like mine used 32211 bearing in place of the 30211 on one end and then use the 30210 on the other.
The seals were all the same, and I found those in several places. I had an inside seal out on the rear bearing and was leaking the oil out over night. but while I was at it, I took the whole thing apart, and started doing a good cleaning of everything. One other thing, I see you have missing back gear on it, the shaft and other stuff is there but the gear is missing. that would be one way to hold the spindle while tightening the chuck. That chuck reminds me of the one on my sherline lathe, but it also has holes in the main cuck body so you can hold it while turning the scroll plate which is the back knurled piece. Another way to hold it while tightening it would be a web wrench.
