Worm Gear Center Drive Maintenance
A. The worm gear center drive must be serviced as follows after each crop cycle
(minimum of once per year):
1. Inspect input and output shaft seals for leakage. Should either the input or output
shaft seals show excessive leakage, the seals should be replaced. All replaced
seals must be installed with generous amounts of #2 Barium/Lithium based
grease or equivalent quality #2 water resistant grease.
2. External dust exclusion seals should be used to keep dirt and water out of internal
seal locations. If the external seals are damaged or worn, replace with new seals.
3. The fl ange drain hole located under the motor mount fl ange must be clear. Clear
the hole with a 12 gauge wire, nail or punch by rotating the tool in the hole to
loosen and remove dirt.
4. All 5/16-18 fl ange bolts and end cap bolts should be torqued to 13-15 ft-lbs
(18-0N-m).
5. To drain gearbox, remove drain plug located at bottom of worm gear and bottom
of side case cover. If oil is contaminated or emulsifi ed, fl ush gearbox with a cup of
specifi ed oil and let drain completely.
6. Replace drain plug and refi ll gearbox through top side fi ll hole to proper operating
level (mid worm gear). Refer to gearbox oil specifi cation. After one or two hours
the oil should be re-checked. Air may be trapped in the gearbox during initial fi ll
ing. Top off with oil as needed.
