With or Without an Elevator
1. Slide the agitator shaft through the large hole in the
center of the drum cover (29).
2. Rotate the agitator so that the air motor is to the left
of the shaft, as shown in Fig. 2, which will align the
three tapped holes in the bottom of the agitator 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, and torque them 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
(see Parts Drawing for blade orientation).
5. Push four cap screws (31) through the four holes in
the blades, and start the lock nuts (32) onto the cap
screws.
For in–drum heavy duty back geared agitator
1. Determine which size adaptor nut (20) is needed.
The adaptor nuts in the kit are double–sided
meaning that each adaptor nut will cover two
agitator shaft sizes. Select the size you need by
placing the adaptors onto the built in agitator shaft in
the drum. The one you should use is the smallest
one that will fit. 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 down using the wrench flats.
3. Place the threaded bung adaptor (34) onto the
gearbox and align the bolt holes.
Installation
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 to 55 in-lb (5.6 to 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, and
torque the lock nuts (32) to 50 to 55 in-lb (5.6 to 6.2
Nm). A gap will remain between the blade halves.
4. Thread the three bolts (28) into the gear box and
torque to 10 ft–lbs (13.5 Nm).
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.
7. Torque the unit to 45 ft–lb (61 Nm). Place the
adaptor of the torque wrench on the top of the unit
to torque.
