Hey, I have this mill and I’ve had the head apart before.
I haven’t had to change that seal but I looked at the manual.

The seal is at the very bottom of the upper head assembly on page 14. The mfg part number doesn’t turn up anything when I google it but the bearing that accompanies it is a 6008 (40mm ID and 68mm OD) so it shouldn’t be hard to find at any bearing supplier. It’s a single lip rubber seal with a metal outer component.
When you refill the reservoir it takes regular ATF btw.
Sorry for the confusion, and thanks for the reply. I have that manual. The part of the machine I'm working on is everything below that oil tank/reservoir. We just lifted the motor with that gearbox and reservoir off and went from there. So there is a long shaft, splined for a foot or so at the top end with a double set of upper bearings (SKF 7206B) followed by an 8" long sleeve and two more bearings lower down towards the end of the spindle. First comes an SKF 7208 B with upper case letters PG stamped next to the number. Then there is a two part spacer collar followed by a final bearing, slightly narrower and having a larger ID inner race SKF 7010C / C7B. I don't know much about bearings - how to tell if they actually need to be replaced, but figured once they are pressed off and in my hand, they might as well be replaced with new ones that are certain to be "good".
So I was able to source the first three but SKF 7010C / C7B is turning out to be a no show at two bearings shops in Peterborough. Both countermen phoned SKF and got the same not available from their customer service reps.
So, If I can find a new one of those, I'll be on my way, but if I can't, what do you think about putting this one back in. There is certainly noting obviously wrong with it but both shops told me there is no way of knowing and remined me of what was involved in taking this thing apart.
That's the first bit. I've never used this mill and only saw it running for a minute. The fellow who sold it to me said that that it was working A-1 but had an oil leak that made oil drip on the work surface. I figured while I was waiting for the Phase-A-Matic phase converter to arrive, I'd get the oil problem sorted. To make a long story short, the actual reason I have this thing apart is to address the oil dripping problem around the spindle. I thought we were going to find an oil seal on the shaft bellow the bearings but did not. The drawing in the manual is so fuzzy I didn't actually figure out what part I was looking for until I got it apart.
Anyway, an old farmer friend told me to pack the bearings with good high pressure grease, put it back together and use thicker oil.
Any suggestions? about the bearing? About the oil seal?
Any comments will be appreciated.
