MAINTENANCE/SERVICE
RECOMMENDED LUBRICANTS
GREASE
Use an SAE Multi-Purpose High Temperature Grease with Extreme Pressure (EP2) Performance and
containing a maximum of 1% moly (molybdenum disulphide).
For driveline slip-joints only, increased moly content (up to 10%) is recommended. IMPORTANT: Do not
use this higher moly content grease on bearings, as it may cause excessive wear in high speed applications.
WOBBLE BOX LUBRICANT
In sickle drive wobble box, use SAE 85W-140 gear lubricant. (API Service Classification GL-5)
Capacity: 2.2 litres (2.3 U.S. quarts)
STORING AND HANDLING LUBRICANTS
Your machine can operate at top efficiency only if clean lubricants are used. Contaminant in lubricants is the
most likely cause of bearing and hydraulic system failure. Use clean containers to handle all lubricants. Store
lubricants in an area protected from dust, moisture and other contaminants. Keep hydraulic couplers and
connectors clean.
SEALED BEARING INSTALLATION
1. Clean shaft and coat with rust preventative.
2. Install flangette, bearing, flangette and lock collar.
The locking cam is only on one side of the
bearing.
3. Install and tighten the flangette bolts.
4. When the shaft is located correctly, lock the lock
collar with a punch. The collar should be locked
in the same direction the shaft rotates. Tighten
the setscrew in the collar.
5. Loosen the flangette bolts on the mating bearing
one turn and re-tighten. This will allow the
bearing to line up.
