3. Attach eyebolt to one end of truss cable with two 5/16” cable clamps. Insert
eyebolt into lower truss anchor and thread on nut a short way.
Important: On the 8” x 56’ augers, the truss cable must be threaded through the reach-arm
bracket as shown in Figure 3.12 and then attached to the eyebolts at the lower
truss anchor.
4. Pull truss cable over truss support brackets, around upper truss anchor and
back over truss support brackets to lower truss anchor, holding it loosely in
place with one 5/16” cable clamp at upper truss anchor, and two 5/16” cable
clamps at each truss support bracket.
Important: Do not tighten cable clamps at this time.
Important: The upper end of augers equipped with truss cables should have an upward bow
before being placed on the transport undercarriage (auger tube will straighten
when fully assembled). Place supports under the discharge end until upward
bow is correct.
• The upward bow should be about 2” on the 46’ and 51’, 3” on the 56’ and
61’, and 5” on the 71’ auger.
5. Place other eyebolt onto lower truss anchor and thread on nut a short way.
6. Insert other end of truss cable through this eyebolt. Pull out all slack and
secure with a cable clamp.
7. Tighten eyebolts to take
remaining slack out of
truss cable and to
maintain the appropriate
upward bow. After tension
is adjusted, tighten cable
clamps on truss support
brackets and upper truss
anchor. Check for proper
side alignment.
Once auger is fully
assembled, adjust truss
cables on all units (because
of initial stretching). Cables
may also require adjustment
for side alignment.
