1. Slide the flight assembly into the auger housing.
2. On 6” Models, fasten the head bearing and flangettes to the outside of the head plate and secure using three
5/16” x 3/4” carriage bolts and nylon locknuts (bolt heads will be to the inside of the head plate, do not tighten
the bolts completely at this time. The angles on the head plate will face towards the discharge end as shown
in Fig. 1 below).
3. Insert the narrow end of the head stub through the bearing (insert from the outside of the bearing) and attach
stub to the end of the flight using two 7/16” x 2 1/2” bolts and nylon locknuts.
4. Attach head plate to the housing flange using six 5/16” x 3/4” bolts and nylon locknuts. Once head plate has
been secured, tighten the three head bearing bolts and secure lock collar into place.

Note: The kit for the 6” units includes a weld-on flanged ring. This ring can be welded to existing housings
that do not currently have the flanged ring. Make sure the head plate is oriented correctly before welding
the flange to the housing.

5. Insert the 1/4” x 1 1/4” square key into the keyway on the end of the head stub. Slide the flex coupler half
with the pinhole, onto the end of the head stub and key, and secure with the 3/8” x 2” roll pin. Tighten the
setscrew on the coupler half to secure square key into place (the flex coupler should set against the head
bearing lock collar).
6. Attach the hydraulic motor to the outside of the motor mount and secure using four 3/8” x 3/4” bolts and lock
washers (See Fig. 2).
7. Slide the other flex coupler half onto the hydraulic motor shaft and secure with the key supplied with the motor
and the setscrew in the coupler.
8. Bolt the hydraulic motor mount to the head plate using four 1/2” x 1” bolts and nylon locknuts.
9. Loosen the setscrew in the coupler half that is on the hydraulic motor shaft. Connect the two coupler halves
together using the chain and connecting links provided. Note: Leave a 1/8” gap between the two coupler
halves, then retighten the setscrew to secure the coupler half to the motor shaft.
10. Bolt the hinged covers (located on the side of the motor mount) to the head plate using two 1/4” x 3/4” bolts,
flat washers, lock washers and non-lock nuts.
WARNING
Do Not connect or disconnect hydraulic components when there is pressure within the system.
Hydraulic systems are highly pressurized. Escaping hydraulic oil, even an invisible pinhole leak,
can penetrate body tissues and cause serious injury.
Use a piece of wood or cardboard when looking for leaks, Never use the hands or other parts of
the body.
When reassembling, make absolutely certain that all connections are tight. If injured by hydraulic
oil escaping under pressure, see a doctor immediately. Serious infection or reaction can occur
if medical attention is not received at once.
Keep all safety shields and devices in place.
6” Hydraulic Drive Assembly (con’t.)
11. Apply a thin coat of clean hydraulic oil to the o-rings on the hose ends. Connect the hydraulic hoses to the
ports in the motor (o-ring fittings do not require pipe sealant). Note: Hoses are not furnished but can be
ordered from the factory or obtained locally (See Parts Page for Part No. identification). The hose
end required for motor connection is 7/8-14 w/O-ring Ports).
12. Check all fittings, hose connections and fastening hardware to ensure everything is tight.

1. Slide the flight assembly into the auger housing.
2. Bolt the head stub into the end of the flight using two 7/16 x 2 1/2” bolts and nylon locknuts.
3. Fasten the head bearing and flangettes to the outside of the head plate and secure using three 5/16” x 3/4”
carriage bolts and nylon locknuts (bolt heads will be to the inside of the head plate, do not tighten the bolts
completely at this time. The angles on the head plate will face towards the discharge end as shown below).
4. Slide the head bearing and plate over the head stub and attach the plate to the flange on the housing using
four 3/8” x 1” bolts and nylon locknuts. Note: only use the two upper and two lower slotted holes in the head
plate for now, the two holes on the sides will be used to fasten the motor mounts hinged doors when it
is installed. The top and bottom hole in the flanged ring will not be used.
Once the head plate has been attached, tighten the three bolts securing the head bearing and tighten the
lock collar into place.
