Kenmore Sewing Machine tension unit assembly links and information
I haven't disassembled, and assembled every kind of upper sewing machine tension units, so I will share links to sites which do, to help people find help on these, and will add more links, as I find them.
Some of these cover the same type of unit, but we learn differently, so one version may be more helpful, than others.

Mysewingmachineobsession blog is another site with a tutorial. If I remember right, she had a couple parts mixed up, but it has been many years, since I worked on this tension unit type, and had messaged her, I can't remember if she fixed it, but the tutorial was very helpful.

This next one is not a Kenmore, but I'm including it, because it shows the type of tension unit with a sealedcap, that pulls straight off, to access the mechanical parts, and I seem to recall having to repair one of these, but don't recall the model it was on. ABSOLUTE SEWING on YouTube-
