Now that I have the bearings in hand, time to install them. First
issue
is how to get at the arbor. My initial approach was to unbolt the
cast-iron table top (TAB-101) and remove it from the sheet-metal
housing
(TAB-110-S). This approach was abandoned because it was too much
trouble to get the two hand-wheel shafts disentangled from the
sheet
metal housing because the tension pins (SP-2711) are difficult to
remove
undamaged without a special tool to prevent the pin from splaying
and
jamming as it is driven out.

Nice writeup.
Ditto.
I haven't had a problem removing or installing dowel, taper and roll
pins with standard flat-ended drift punches, or custom length /
diameter punches turned from steel or brass welding rod. If access
is
poor you could drill the end of rod stock to make a starter punch
that
holds the pin in line.
Also, consider installing springy roll pins vs the tapers.
Sometimes
it works, sometimes not.
Using a slightly smaller punch with tape around the end (to center
it)
can work, too. The pin never touches the sides.
The taper pins are on my South Bend lathe, which I'm trying to keep
original, or at least not damage it when installing homebrew
replacements for missing parts. .
There are gunsmithing roll pin punches with a centering dimple that
keeps the punch from scratching the finish. I couldn't care less on
most of the stuff I have that uses roll pins.
The pins I didn't drive out are roll pins, not taper pins. The pin
sticks out about 1/4 inch on either The problem is that as one tried to
drive the pin out, the end being driven splayed, making it harder to
get the pin through the tight-fitting cross hole in the 5/16 inch
diameter shaft.
The driving tool must prevent splaying, or everything will jam tight.

With roll pins..you chamfer the end that goes in on your grinder/belt
sander and then they go in easily. Doesnt take an effort to drive in
a roll pin.
