3.3. INSTALL TRUSS SUPPORT TOWERS AND TRUSS
TUBES
Note:
Due to rigidity of the tubular trussing, do not put an upward bow in the auger.
Assemble trussing with main auger tube straight/level and well supported over its
length. When assembling the truss system, DO NOT tighten any bolts until all
components are in place.
• See Figure 3.19 and Figure 3.22 for the X160-85.
• See Figure 3.20 and Figure 3.23 for the X160-105.
• See Figure 3.21 and Figure 3.24 for the X160-125.
When assembling the truss system, do not tighten any bolts until all compo-
nents are in place.
1. As shown in the appropriate figures (Figure 3.19, Figure 3.20, Figure 3.21),
attach pairs of low and high truss tower brackets to the truss-attach brackets
welded to the auger tube, using eight 1/2” x 1-1/2” bolts and locknuts per
truss tower pair.
2. Thread a 1” hex nut as far as possible onto the threaded rod end of a truss
adjust tube.
3. Insert the threaded rod end of the truss adjust tube into the truss anchor
bracket, and bolt the opposite end to a tube connect plate that has been first
bolted to the adjacent truss pair.
4. Thread an second 1” hex nut a short distance onto the threaded rod end of
the truss adjuster tube.
5. According to the diagram for your specific model, work from one end of the
tube toward the opposite end:
a. Install tube connect plates between truss tower pairs.
Note:
Truss towers connect to their tube connect plate using two 1/2” x 2-1/2” bolt and
locknut.
Note:
Five-bolt and seven-bolt tube connect plates are used in specific locations. When
installing the seven-bolt connect plates, ensure that the three 1/2” bolt holes
should be closest to the boot, and the 3/4” bolt hole should be closest to the
discharge spout.
b. Install truss tubes between tube connect plates.
c. Install short and long cross-brace tubes.
Note:
Single cross-brace tubes are used between the two truss towers closest the
ends of the main auger tube, and two cross-brace tubes are required between all
other truss tower sets.
d. Install the remaining truss adjust tube.
6. Tighten all truss, tube, and cross-brace bolts and nuts, but do not tighten the
1” hex nuts on the truss adjust tubes.
7. Install pairs of cross-brace clamps where the cross-brace tubes cross in an
”X” pattern using two 7/16” x 1-1/4” bolts and locknuts.
8. Adjust the “outer” 1” hex nuts on the truss adjust tube until the truss tubes are
tight and the auger tube is straight (ie. appears flat and well aligned, and
does not have any noticeable bow).
