Couple of observations
I've got a 3 digit machine but must have been near the end since it had the Z-axis brake. No mention of this in the install guide but there's only really 2 wires on the C1 contactor that needed to be changed to the new brake
My X axis drive is tucked all the way over in the left of the case, real pain to get the new drive with mounting adapter into that corner
When installing the new motors if they don't slide in nice, loosen the coupler screw on the ball-screw side, the shafts on the new motors must be slightly different or something, both my Z and Y axis motors wouldn't go all the way in (stopped pretty much dead about .0750" - .100" short) and as soon as I loosened the coupler they slid in the rest of the way.
You do not need to remove the upper chip guard or rear column cover plate as far as I can tell. Mine has sound deadening all over the back and I would have had to cut everything apart so I tried leaving it and more or less everything worked fine (see next item)
You can change the Y axis motor even if the machine is basically against the wall (I have about 3" behind the motor to the wall) but it's a real pain. Did everything standing in the chip-tray reaching down over the upper chip guard (see previous item) to the motor
Did a quick power up and all axis are working, X gets up to about 104ipm
Need to do some cycles tomorrow to see how all axis are performing.
Also need to get a hold of Tormach next week to see about my A axis, I'm guessing it should still work since there has been no mention of it not working anywhere but I just want to make sure. For now I unhooked the power to it just in case.
Later
