IMPORTANT: To prevent roll knock, apply Quick Metal compound to roll shaft where bearing rides. Thoroughly clean roll shaft and bearings using denatured alcohol and apply solventless activator. Make sure to knead (mix) Quick Metal material before applying to shaft. Failure to knead material will result in poor bonding and curing. NOTE: See John Deere dealer for Quick Metal and primer solventless activator. 6. Liberally apply PM38651 Quick Metal to area of shaft where bearing rides. 7. Apply PM37509 Klean N Prime to inside of bearing flats. 8. Assemble bearing on shaft and tighten mounting nuts. 9. Check roller clearance at hole through sidesheet. Loosen bearing support hardware and reposition roll as needed. |
