 Do this with all of the linear bearings and holders, and compare them;  they should look the same.
-A good way of checking the bearing holders is to insert bearings into all of them and then put a piece of your precision steel rod through them:
+A good way of checking the bearing holders is to insert bearings into all of them and then put one of the precision steel rods through them, as shown below. Get out one rod, and examine the ends;  one end may be smoother than the other. The smoother end is the end to be inserted through the linear bearings.  Insert it carefully, right down the middle, without banging the end of the rod against the bearing balls inside the linear bearings.

+Also add a terminal block (six positions per extruder) and attach it with an M3x16mm button-head screw and nut (one set per extruder).
+Note: The terminal block on the Duo x-carriage may be slightly offset to one side as the terminal pitch does not exactly match the x-carriage slots. For the Duo, try putting both screws through the second hole in from each end. One screw then fits into a vertical slot and the other screw fits into one of the diagonal slots.
+You should also attach the X tensioner using the M3 x 16mm screw through the center and on of the other M3 screws to lock it in position as shown below (from bag 17a):

-The loose screw shown above will be used later to attach the synchromesh cable to the X tensioner.  Put this screw back in the X tensioner bag for now, along with an identical screw and nut that will be used later on the other side of the X carriage.
+The remaining 2 x M3 10mm screws and 1 M3 nut (one loose M3 screw shown above) will be used later to attach the synchromesh cable to the X tensioner.  Put these screws and nut back in the X tensioner bag for now.
-(Apparently some early adopters got M2.5x16mm socket-head instead of the M3 for attaching the terminal block.  That's what is shown above.  If you got the M3, you may have to use the nut to crank down the screw head  -- or vice versa  --  into the terminal block. The M3 nuts fit in the terminal very tight and it will have to be jammed in. You can take the M3x16mm socket-head and thread the M3 nut on the end. You can then align the nut on top of the terminal and gently tap it in, ensuring that the nut stays flat. The terminal will flex somewhat, but as long as you are not using excessive force it should be fine. After the nut is seated in the terminal, you can back the screw out and insert it from the bottom side to attach the terminal to the x-carriage. The picture below shows the terminal already mounted, DO NOT try to jam the nuts into the terminal while it is on the aluminum frame!)
