With With Without an
1. Install the agitator shaft (33) by threading it into
the stub (6) on the bottom of the back-gear
housing (1). See Figure 2.
2. Slide the agitator shaft through the large hole in
the center of the drum cover (not shown).
3. Rotate and align the three tapped holes in the
bottom of the back-gear housing with the three
through holes in the drum cover.
4. Thread three hex head screws (45 not shown)
with thread sealant (not provided) up through the
drum cover and into the bottom of the housing.
Torque them to 75 in-lb (8.4 N-m).
5. Assemble one pair of agitator blades (34) so that
the four holes in the blade halves are lined up.
6. Push four cap screws (35) through the four holes
in the blades, and start the four lock nuts (36)
onto the cap screws.
7. Slide the loose blade assembly up the shaft, and
position it approximately 13 in. (33 cm) from the
bottom of the shaft.
8. Tighten the lock nuts evenly to draw the blades
together until they are tight on the shaft. Torque
the locknuts to 50 to 55 in-lb (5.6 to 6.2 N-m). A
gap will remain between the blade halves.
9. Repeat steps 5 and 6 with the second pair of
agitator blades.
10. Position the second blade assembly near the
bottom end of the shaft, but not on the bottom
plug (40).
11. Rotate the lower blade assembly so that it is
oriented 90 degrees relative to the upper blade
assembly, and torque the lock nuts to 50 to 55
in-lb (5.6 to 6.2 Nm). A gap will remain between
the blade halves.
