TM 5-3895-374-24-2 7. The deflector rubber in the discharge hood should extend four inches below the hood.  If it does not, it should be replaced. 8. Inspect the discharge hood for wear.  If the steel has worn away from use, repair or replace the hood. 9. Inspect all troughing rolls.  They must turn freely in the frames.  If any do not turn freely, replace them with new ones.  If the outside shell of the roll is worn flat or has holes it should be replaced. 10. Inspect the trough frame to determine if it is bent or damaged.  Repair or replace if necessary. 11. Inspect all return rolls.  The shaft must turn freely.  The outside shell of the roll should not be worn flat or  have holes.  Replace the roll if the shaft does not turn freely or if the shell is damaged. 12.

Install the pulley onto the head shaft and slide the two bushings onto the shaft. Install the fasteners holding the bushing in place and securing the shaft in the head pulley. 3. Slide the pillow block bearings onto the shaft. 4. Using a sling around the head shaft on either side of the pulley, lift the assembly to the conveyor  frame.    Make sure the reducer end of the head shaft extends out the correct side of the conveyor. 5. A  bearing  adjustment  bolt  is  mounted  on  each  side  of  the  conveyor  below  the  mounting  of  the  pillow  block bearings.    Unless  these  have  been  moved,  or  the  pulley  does  not  sit  level,  they  should  not  have  to  be  moved.
