6. Firmly press the neighboring sections together while tightening the two
M3 x 20 mm screws through each tie bar into the flanges of the sections.
Alternately tighten the screws into the flanges and those into the sides of
the extrusions to ensure that each tie bar is drawn into the corner of the
extrusion.
IMPORTANT: Be careful not to overtighten these screws.
7. Inspect the joint to see that the sections are well aligned, with minimal
irregularities and gaps.
8. Repeat steps 6, 7, and 8 for each pair of sections. It may be necessary to
use suitable blocks to support the row of sections so that neither the
motor housing nor the bottom flange of the base section touches the
work surface while you are connecting the motor drive section.
9. Center one of the support bars across the rear of the motor drive section
over the holes on the rear surface of that section.
10. Insert two M4 x 20 Phillips sems screws through the holes in the support
brace into the holes in the motor drive section, and tighten.
11. Go to the next section, Installing the Belt.
Installing the Belt
Refer to Figures 3-5 through 3-9.
1. Turn the assembled Pass-Thru mechanism over so that the motor points
upward.
2. Referring to Figure 3-6, locate the tensioner ramp in the base section.
Compress the spring until the hole in the tensioner ramp is aligned with
a hole in the base section. Insert an 0.050" Allen wrench or a paper clip
through the holes. This sets the idler pulley for zero belt tension.
