Maintenance
Auger And Inner Bearing
Replacement
Removal
1. Remove rear grating over auger assembly.
2. Run screed extension all the way out.
NOTE: This provides room to stand in behind auger
back to remove top portion of auger cover. Auger
cover is in three pieces with a small tack to hold
cover together while building.
3. Remove four nuts holding cover (Figure 10-5,1) on
and pry cover apart.
4. Clean asphalt build up from around cover.
NOTE: Heating asphalt may be required.
5. Remove middle and bottom portion of cover by
laying on conveyor under engine.
6. Rotate augers so that master link is centered at
front.
7. Loosen auger chains by sliding auger motors
(Figure 10-5,4) down from backside after loosening
the two bolts securing mounting brackets (Figure
10-5,5).
8. Remove auger endmounts (Figure 10-5,8,9) so that
augers can be removed through opening in sides.
9. Remove augers (Figure 10-5,15,16) and lay augers
on the ground in the same position as removed. This
will help insure proper installation of the new augers.
10. Check inner auger bearing (Figure 10-5,12) and
replace at this time if faulty.
Installation
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.
1. Install new augers (Figure 10-5,15,16) making
sure that wear plates are on correct side to auger
material outward.
2. Tighten bearing setscrew to help hold auger shaft
from moving outward.
3. Slide auger collar (Figure 10-5,6) on end of auger
shaft and bolt endmount (Figure 10-5,8,9) back on.
Torque mounting screws to 78 ft. lbs. (106 N•m)
4. Push collar (Figure 10-5,11) all the way in against
endmount (Figure 10-5,8,9) and attach with
setscrews (four setscrews, two on outside and two
on inside).
5. Replace bronze bushing (Figure 10-5,7) in the
endmounts.
6. Place auger chains back on and adjust auger
motors (Figure 10-5,4) up to tighten chains.
Use a pry bar under motor to pry up, then snug
bottom motor mount bolts (make sure chains have
approximately 1/4” of slack).
7. Make sure motor is level then tighten top and
bottom bolts. to a torque of 150 ft. lbs. (155 N•m). Do
the same for the other side.
8. Lubricate chains.
9. Place auger cover (Figure 10-5,1) back in place
making sure slot for auger shaft is sealed shut.
10. Place grating back on over auger.
11. Run augers and make sure everything is correct.
NOTE: Auger chains can be lubricated each day by
spraying oil or chain lube in through slots where
auger motor is adjusted.
