Oil seal

1. Remove the acorn nut, hex nut, and washer that hold the "planetary" agitator section on the transmission shaft.
2. Remove the trim ring (if any) around the same.
3. The agitator section should now be able to be worked free.
4. Remove the retainer clip on the top of the agitator shaft. (Some models have a pair of hex nuts here; if so, remove those.)
5. Pry the gear up and off the shaft. Remove the square key from the shaft keyway at the same time.
6. Tap gently on the top of the agitator shaft to drive it out from the bearings and grease seal.
7. Recommend removing and replacing the top bearing at this time; it's inexpensive to replace, if you're in this deep.
8. Use a suitable diameter piece of round steel stock to drive out the lower bearing and oil seal. I don't recommend using the agitator shaft.
9. Clean thoroughly, insert a new bottom bearing and oil seal, drive in place with a rubber mallet.
10. Replace agitator shaft through oil seal and bearing, tap gently into place.
11. Fill cavity with approved lubricant. I use USP-grade mineral oil, as it is food-safe and provides satisfactory lubricity.
11. Install top bearing, tap gently into place.
12. Reverse steps 5-1 to reassemble.
