FINAL DRIVE GEARBOX MAINTENANCE PROCEDURES
A. The fi nal drive gearbox must be serviced as follows after each crop cycle:
1. Inspect input and output shaft seals for leakage. Should either the input or out
put shaft show excessive leakage, the seals should be replaced. All replaced
seals must be installed with generous amounts of #2 Barium/Lithium based grease
or use equivalent quality #2 water-resistant grease.
2. External (dust exclusion) seals should be used to keep dirt and water out of inter-
nal seal locations. If the external seals are damaged or worn, replace with new
seals.
3. The seal drain hole located on both input caps must be kept clear of dirt. Clear the hole
with a 12-gauge wire, nail or punch. Rotate the tool to loosen and remove dirt. Make sure the
vent hole in the expansion chamber is free of dirt or debris.
