11. Install wheel frame clamp top and bottom (12) to lower end of tube (see
Figure 3.1) with four 5/16" x 1-1/2" bolts (13) and locknuts (14). Do not
tighten.
12. Attach lower support tubes (24) to wheel frame clamp (12) with two 1/2" x 1-
1/2" bolts (28) and locknuts (29).
13. Adjust the position of the lower wheel frame clamp so that the back of the
hopper is elevated ~1/2" from the ground (see Figure 3.1). Tighten bolts and
nuts.
14. Install the gearbox (30) on the auger shaft and secure with a 3/8" x 2" (31)
bolt and locknut (32).
15. Mount transport handle (36) to the bottom of the gearbox (30) with 3/8" x

3/4" bolts (37) and lock washers (38).
16. Connect bottom bracket (33) to gearbox (30) with 3/8" x 3/4" bolts (34) and
lock washers (35).
17. Place two washers (50) on gearbox (30) and mount top bracket (33) and
guard back plate (51) on gearbox (30) with three 3/8" x 3/4" bolts (34,48) and
3/8" lock washers (49).
18. Insert 1/4” x 1-1/2” key (39) on exposed gearbox shaft (30), and mount pulley
(40) on gearbox shaft.
19. Insert 1/4” x 1-1/2” key (39) on motor shaft (41) and mount 3.5" pulley (42) on
shaft.
20. Rotate tightener pin (9) as far as it will freely turn so that the handle points in
the direction of the hopper.
21. Place the gas engine (41) on the motor mount (5), and using a level or
straight edge, align the ends of the gearbox (30) and motor (41) shafts.
22. Adjust the motor position so that the center of the shafts are approximately
23”–25"(58.4 cm - 63.5 cm) apart. Refer to Figure 3.4.
23. Use c-clamps or vice grips to temporarily secure the motor to the mount.
24. Install the B-70 belts (43). (NOT Provided). The belts should deflect 1/2" to 3/
4" when pushed on with a 5 lb force. If they do not deflect properly, remove
the clamps and belts, adjust the position of the motor, and re-align. Repeat
this step until the belt tension is adequate. Remove the c-clamps or vice grips
when finished.
25. Mark hole locations on the motor mount and remove the motor. Drill holes
through to match the size of the mounting bolts, and install motor using bolts
and locknuts.
Note: The holes could be die ground to form slots in case of belt slippage after initial
break-in. This will save time later if any adjustment is required.
26. Attach guard front cover (47) and end cover (52) to backplate (51) with six
self-tapping screws (53).
27. Affix decals as shown in “Safety Decals” on page 12.
Note: The final rpm for the auger should be between 500-600. Example: for 3200 rpm,
using a 3.5" motor pulley, 1:1.5 gearbox, 12.7" gearbox pulley, final rpm = 588.
