I just broke the belt drving the spindle on my Excello 602...

The top of the machine is almost exactly like a 2J bridgy. I do
remember having a totaly awful time with this belt when I rebuilt the
head several years ago.

Anyone have tips or a procedure for spindle belt replacement?

If you're talking about trouble wrestling with the belt while the
pulley spring is fighting you, look for a couple holes in the spring
retainer at the end of the motor shaft. If it's similar to a
Bridgeport or my Supermax, the holes line up with tapped holes in the
pulley flange. Install cap screws in the holes to compress the spring
and keep the pulley flanges spread.

Start the spindle, turn the speed all the way down, turn off the
motor, install the screws. Turn the speed control to max with the
motor stopped (allows the spindle pulley flanges to spread) and the
belt will be slack.
