Setting the Thrust Adjuster
4.15. Install Truss Support Towers and Truss Tubes
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.
1. Attach pairs of low and high truss tower brackets to the truss-attach brackets welded to the auger tube.
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 a 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 plate pairs between truss tower pairs.
Note
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.
