REPLACEMENT SPOUT (PART NO. 1047420)
for
13” SWING-AWAY AUGERS
Before beginning assembly it is suggested to read through these instructions and lay out all items from the kit to
ensure all parts are accounted for. This not only helps you become familiar with the parts and assembly procedures,
but also makes you aware of what tools, equipment or materials you may need to complete the installation process.
Remove Existing Spout, Gearbox & U-Joint
The replacement spout is shipped with all necessary hardware for reassembly. Installation of the new spout will
require the removal of the existing spout, and the upper gearbox and u-joint. The gearbox and u-joint will then be
installed into the new replacement spout. The Owner’s & Operator’s manual shipped with your unit can also be used
for assistance if necessary.
1. Remove the hardware securing the existing spout to
the inlet hopper as shown in Fig. 1 below.

2. Using a sling, raise the spout and incline tube high
enough to allow clearance so the spout, gearbox
and u-joint can be removed from the incline tube.
3. Open the access panels on the spout and disconnect
the incline flight from the gearbox shaft.
4. Remove the hardware securing the spout to the incline
tube and slide spout, gearbox and u-joint off the
incline flight and away from the incline tube (See
Fig. 2 below).
5. Remove the gearbox and u-joint from the spout.

Install Replacement Spout
1. Raise the hinged door on front of the spout assembly and temporarily remove the side access door. Remove the
bolt kit from inside the spout.
2. Mount the gearbox into the spout and secure using the 3/8” x 1” bolts and lock washers provided. Torque the
bolts to 35-40 ft. lbs. (47.5 N·m - 54.4 N·m).
3. Reposition the u-joint. It is important for the u-joint to be flush with the end of the gearbox shaft. The
gearbox shaft and u-joint may already have had anti-seize compound applied, if not, remove the u-joint and
apply anti-seize compound, reinstall so it is flush with the end of the shaft (See illustration below).
If the u-joint did not have to be removed, loosen the setscrew and position the u-joint so it is flush with the end
of the shaft (See illustration below). Tighten setscrew.

Reinstall Spout and Incline Tube
to Inlet Hopper
1. Apply anti-seize compound to the output shaft on the gearbox. Attach the incline flight to the shaft (align the
keyway in the flight with the woodruff key and slide flight onto shaft). Use a 1/2” x 3 3/4” bolt and locknut to
secure flight to shaft (See illustration on following page).
2. Place a 7/8” (22 mm) long spacer bushing onto each of the threaded studs welded to the spout. Slide the tube
ring onto the studs and secure using flat washers and nylon locknuts.
IMPORTANT! Be sure to install the bushings between the spout and tube ring, the spout must be able
to swivel on the tube.

Reinstall Spout and Incline Tube to Inlet Hopper (con’t.)
3. Apply anti-seize compound to the splined shaft on the lower gearbox inside the inlet hopper.
4. Place the two 1” O.D. x 13/32” I.D. x 1/4” thick flat washers over the threaded studs on top of the main inlet
hopper as shown below.
5. Using a sling, position the spout assembly directly over the opening in the main inlet hopper and carefully lower
the spout while aligning the u-joint with the splined shaft on the lower gearbox.
Completely lower the incline tube and spout until the spout flange sits flat against the top of the hopper (the
spout flange will be on the inside of the 1” O.D. washers previously installed over the studs).
6. Secure the spout flange to the top of the inlet hopper using four 2 1/4” O.D. flat washers and locknuts (See
illustration below). IMPORTANT! Do Not tighten down the 2 1/4” O.D. washers completely, the spout must
be able to rotate freely on top of the hopper.
7. Make sure the hinged door and side access door are securely closed before beginning auger operation.
