Mounting the x-motor and x-idler
First step is to drop the pre-assembled z-bearing-guide-bottom's onto the z-drive-stud attached to the z-motor and the z-idler as shown.
Figure 1 - Running down the z-axis drive nut and clamp
Press (1) M8 nut (5/16 if using 5/16 threaded rods) into the z-elevator-clamp, then spin onto the threaded z-stud about half way down towards the z-motor. The center hole through the clamps are offset a little bit, so orient them so that wider part of the clamps face away from each other. If they are reversed they won't mate to the the x-motor and x-idler in the next step.
Duplicate the process on the other size on the z-tensioner. Ensure that both z-elevator-clamps are the same distance down so that they are level with each other.

Next we are going to lay the smooth x-bar's to across the clamps. They should hang over by the same amount on each side. If your using Isaac length rods they will extend approximate 3/4" past the clamps. If your using Mendel length rods they will extend much further.

Now lay the x-motor and x-idler on top of the z-elevator clamps and press onto the nut. and bolt together using the inner most for holes. Only tighten the assembly finger tight until final alignment. See Phase 4 Step 4 for a detailed exploded view of the 4 inner bolts.

Now lay the pre assembled z-bearing-guide-top on top of the x-motor and bolt together using the outer 4 bolt holes. Only tighten the assembly finger tight until final alignment. See Phase 4 Step 3 for a detailed exploded view of the 4 outer bolts.

Next assemble the z-rod-clamp to the top of the Isaac as shown. Leave the M8 nuts loose until final adjustment. Leave the M4 hardware loose as well until you drop the smooth rod though in a minute.

Finally drop in the z-bar from the top, through the z-bar-clamp through the x-motor/x-idler and push into the z-motor/z-tensioner. The bar should press in firmly into the z-motor and z-tensioner assemblies with a little pressure. If you can't get them to go in, make sure the rod is going in straight. You want a tight fit, but not so tight that you can't get it back out later.
