DRIVELINE MAINTENANCE
The Driveline should be serviced every 8 hours of operation. Refer to (Figure 5-3)
1. Disconnect the driveline from the Tractor PTO and from the Gearbox input shaft.
2. Pull the driveline halves apart.
3. Release the Shield Cones from the shield tubes by pressing down on the retaining tabs located under the access
holes on the back of the shield cones (there are 3 tabs on each cone) and separate the shield tubes from the
cones exposing the driveshaft inner and outer tubes.
4. Thoroughly clean old grease from the tubes and apply a thin coat of multi-purpose grease to the outside of the
inner tube (male) section.
5. Re-assemble the shielding on the two halves and then re-assemble the driveline halves.
6. Put 1 or 2 shots of grease in the lube points for the shield bearing locations.
7. Grease the Cross Bearing in the fittings on both ends of the shaft.
8. Apply a lite coat of oil to the Slide Collar (Tractor End) and the Push Pin (Implement End) to prevent rust from
forming making their functions difficult.
9. Re-attach the Driveline to the Gearbox Input Shaft and then to the Tractor PTO shaft.
10. Pull on each end of the shaft to make sure the shielding is secure to the Driveline and the driveline is securely at-
tached to the PTO Shaft and the Input Shaft of the Gearbox.
