See Table 3.9. for a list of parts required to install the X130-84/X130-94 truss
towers and truss tubes, as well as for figure references that apply to the
diagrams below.
• For the X130-84 models, see Figure 3.14 and Figure 3.15.
• For the X130-94 models, see Figure 3.16 and Figure 3.17.
Note: Due to rigidity of the tubular trussing, truss tubes should be tightened to provide
only a small upward bow (approximately 1”) at the auger tube spout end.
Note: When assembling the truss system, do not fully tighten any bolts until specifi-
cally instructed to do so.
1. Ensure that auger tube sections are supported in such a way that the tube is
as straight as possible. Use additional supports, shims, and blocks as
required.
2. Attach pairs of low and high truss tower brackets to the truss-attach brackets
welded to auger tube.
3. Install the following truss components:
• tube connect plates between truss tower bracket pairs
• the truss adjuster plate
• truss adjust tubes (short and long), with 1” nuts installed far apart
• cross-brace tubes
Note: Seven bolt truss tube connect plates must be oriented so the three 7/16” bolt
holes are closest to the discharge spout.
4. Adjust the long truss adjust tubes:
• Rotate the 1" hex nut pairs on both long truss adjust tubes until they lock
together tightly on either side of their truss tube anchors.
• When fully tightened, the truss tower brackets should be positioned at a
90 degree angle with respect to the auger tube, and should not lean to
either side.
5. Adjust the short truss adjust tubes:
• Tighten the two 1" hex nuts on the inside of the tube adjust plate until
there is enough tension in the truss tubes to create a slight upward bow in
the tube (no more than 1” as measured from the tube support and the top
of the tube, just before the tube cap).
• When tightening the nuts, alternate between the two nuts frequently
enough to ensure that they are tightened equally, and that the same
amount of threaded rod is exposed on each side.
• Rotate the outer 1” nuts until they lock tightly on each side of the tube
adjust plate.
6. Install pairs of cross-brace clamps where the cross-brace tubes cross in an
“X” pattern, and tighten fully.
7. Fully tighten cross-brace tube nuts at the truss joiner plates and at the tab
between truss tower pairs.
8. Check that all nuts are firmly tightened.
