Assembly
3. FLIGHT AND SHIELD ASSEMBLY (cont.)
E. Attach sweep back shield splice plates (8 & 9) to
back side of the sweep back shield. Use eight 5/16" x
3/4" hex head capscrew and nylon locknuts for each
upper splice plate. Use four 5/16" x 3/4" long hex
head capscrews and nylon locknuts for each lower
splice plate. (See Fig. 9 & 10.)
F. Slide the flight connecting stub (10) through the
bronze bearing (11) and into the next flight section.
Connect the flight sections together using two 5/8" x
4" hex head capscrews and nylon locknuts.
(See Fig. 10 & 11.)

G. Repeat steps C-F for the other add-on sweep back
shield and flight sections. (NOTE: Units that use four
or more sections of flight include a sweep carrier
assembly that is used in conjunction with a truss
stand. (See Fig. 6 on page 20 for locations.) A cable
truss is also provided for the sweep back shields on
these units. The truss stand will fasten to the sweep
carrier assemblies. Fasten the truss stand to the
sweep carrier with 3/8" x 1" long hex head capscrews.
(See Fig. 12 on page 24.) Use 3/8" x 3-1/2" hex head
capscrews to connect the sweep carrier, sweep back
shield and bearing stand together.
The sweep flights are indexed to achieve “timed”
connections ( A “timed” connection is where the
flight pitch does not change across the connection.)
When bolting timed flight sections together at the
bearing stand, position the flight ends so they are
open 90° to 180° to one another.
