1. Slide the agitator shaft through the large hole in
the center of the drum cover.
2. Rotate the agitator so that the air motor is to the
left of the shaft, as shown in
position, the three tapped holes in the bottom of
the agitator align with the three through holes in
the drum cover.
3. Thread the three hex head screws (25) up
through the drum cover and into the agitator.
Torque the screws to 75 in-lb (8.4 N•m).
4. Assemble one pair of agitator blades (28)
so that the four through holes in the blade
halves are lined up. For blade orientation, see
Models 26B630, 26B631, 238250, page 33
Models 26B632, 26B633, page
5. Push four cap screws (31) through the four holes
in the blades, and start the lock nuts (32) onto
the cap screws.
6. Slide the loose blade assembly up the shaft, and
position it approximately 13 in. (33 cm) from the
bottom of the shaft.
7. Tighten the four lock nuts (32) evenly to draw the
blades together until they are tight on the shaft.
Torque the locknuts to 50–55 in-lb (5.6–6.2 N•m).
A gap will remain between the blade halves.
8. Repeat steps 4 and 5 with the second pair of
agitator blades.
9. Position the second blade assembly near the
bottom end of the shaft, but not on the bottom
plug (20).
10. Rotate the lower blade assembly so that it is
oriented 90 degrees relative to the upper blade
assembly. Torque the lock nuts (32) to 50–55
in-lb (5.6–6.2 N•m). A gap will remain between
the blade halves.

1. Determine which size adaptor nut (20) is needed.
The adapter nuts in the kit are double-sided so
that each adaptor nut fits two agitator shaft sizes.
Select the size you need by placing the adaptors
onto the built in agitator shaft in the drum. Use
the smallest size that fits. There should only be
a small amount of slop between the adaptor nut
and the shaft.
2. Thread the adaptor into the gearbox output shaft
(6) with the side you are going to use pointed
down. Tighten it using the wrench flats.
3. Place the threaded bung housing adaptor (34)
onto the gearbox and align the bolt holes.
and
4. Thread the three bolts (28) into the gearbox and
torque to 10 ft-lb (13.5 N•m).
5. Align the adaptor nut to engage the built-in shaft
in the 55-gallon drum.
6. Slowly screw the unit onto the threads on the
center bung fitting of the 55-gallon drum. Hand
tighten to secure the unit. The unit should not
easily unthread from the drum.
