                5.2 MAINTENANCE
              
            
            
              By following a careful service and maintenance pro-
            
            
              gram for your machine, you will enjoy many years
            
            
              and trouble-free operation.
            
            
              
                5.2.1 DRIVELINE MAINTENANCE
              
            
            
              The PTO driveline is designed to telescope to al-
            
            
              low for dimensional changes as the machine goes
            
            
              through its operational range.  A tubular guard en-
            
            
              closes the driving components and is designed to
            
            
              turn relative to the driving components.  The drive-

              line should telescope easily and the guard turn
            
            
              freely on the shaft at all times.  Annual disassem-
            
            
              bly, cleaning and lubrication is recommended to in-
            
            
              sure that all components function as intended.  To
            
            
              maintain the driveline, follow this procedure:
            
            
              1. Remove the driveline from the machine.
            
            
              2. Pull driveline apart.
            
            
              3. Use a screwdriver to fip the lock tabs on
            
            
              each end.  There are 3 tabs per guard.
            
            
              4. Pull the shaft out of the plastic tubular
            
            
              guard.
            
            
              5. Use a solvent to clean the male and fe-
            
            
              male portions of the telescoping ends.
            
            
              6. Apply a light coat of grease to each end.
            
            
              7. Use a solvent to wash the grooves on each
            
            
              end where the tabs are located.  Clean
            
            
              each end also.
            
            
              8. Apply a light coat of grease to each
            
            
              groove.
            
            
              9. Insert the shaft into its respective guard
            
            
              and align the tabs with the holes.
            
            
              10. Insert the tabs through the holes and seat
            
            
              in the groove.
            
            
              11. Turn each tab to secure guard to shaft.
            
            
              12. Check that each guard turns freely on the
            
            
              shaft.
            
            
              13. Apply a light coat of grease to the telescop-
            
            
              ing components.
            
            
              14. Assemble the driveline.
            
            
              15. Check that the driveline telescopes easily.

              16. Replace any components that are damaged or
            
            
              worn.
            
            
              17. Install the driveline on the machine.
