When I got my first (used) table saw I took it apart as much as I could, but I couldn’t get apart those trunnion rods. I put it all together after cleaning and some repair, and it has worked well for decades.

One of the trickiest adjustments to make on a contractor saw is to fix the problem of alignment of the blade with the miter slot changing when you tilt the blade. The problem is caused by getting those rods twisted compared to one another. I was very lucky to not be able to loosen them, since I wouldn’t have known then how to get them properly adjusted.

So my advice is to leave them attached. If you have loosened them, use a piece of glass flat touching both rods to make sure they are parallel when you tighten.
