10. Remove augers and lay augers on the ground in
the same position as removed. This will help insure
proper installation of the new augers.
11. Check inner auger bearings and replace if faulty.
(Figure 5-30)
NOTE: When installing the new augers, be sure to
align augers the same as the removed augers.
It is very easy to install augers backwards.
12. Install new augers making sure that they are on
correct side to auger material outward.
13. Tighten bearing setscrew to help hold auger shaft
from moving outward.
14. Slide auger collar onto the end of the auger shaft
and bolt end mount back on. Torque mounting bolts
to 78 ft. lbs. (106 N•m).
15. Push collar all the way in against end mount and
attach with two (2) setscrews, one (1) on outside and
one (1) on inside.
16. Replace bronze bushing in the end mounts.
17. Place auger chains back on and adjust auger
motors up to tighten chains. Use adjusting bolt to
tighten motor, then snug bottom motor mount bolts
(make sure chains have approximately 1/4” of slack).
18. Make sure the motor bolts at top and bottom are
tight and torque to 150 ft. lbs. (155 N•m). Do the
same for the other side.
19. Lubricate chains.
20. Place grating back on over auger.
21. Operate augers and make sure everything is
correct.
NOTE: Auger chains can be lubricated each day by
spraying oil or chain lube through the slots
where auger motor is adjusted.
