TM 5-3895-374-24-2 2. Inspect the head shaft for damage and to determine if it is straight. If the shaft mounted gear reducer swayed during operation, it would have been caused by a bent head shaft. Replace the head shaft. 3. Inspect the pulley end plates for damage or cracks. Repair or replace the pulley if either end plate is damaged. The pulley face has been vulcanized with rubber. If this rubber is worn off, re-vulcanize 50 duro-meter rubber to the pulley face or replace the pulley. 4. Inspect the head pulley bushings. If they are damaged, cracked or worn, replace them. 5. The scraper rubber must extend beyond the scraper back up plate by at least one inch. If it does not, adjust the rubber so that it does or if necessary, replace with a new rubber. 6. The scraper extra weights are adjustable on the scraper. Position these so that the scraper does not bounce when the belt is running. This means adjusting their location after start up (but not while the conveyor is running). 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. C. Assembly 1. Install the two keys for the pulley into the head shaft. 2. 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. If the belt is in place, the pulley will have to be slid into place from the side. A come along may have to be used to pull the pulley into position. 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 page 3 - 1246
