Cleaning the Agitator Shaft and Seal
CAUTION
Keep the agitator upright. Do not lay it on its side or
upside down, or liquid may flow down the shaft and
into the gear reducer area.
If any material is on the shaft (6) within 1/2 in. (13 mm) of
the housing (13), it must be removed to prevent damage
to the bearing seal (14*). If the flexible lips on the bearing
seal are torn or worn such that they do not make contact
all the way around the shaft, the seal must be replaced. A
worn seal may allow foreign material into the bearing and
cause premature failure. See Servicing the Gear
Reducer on page 11 for instructions on getting access to
the seal and for the Bearing Replacement Kit Part No.
Cleaning an Agitator with a Siphon Kit
The procedure for flushing and cleaning the siphon tube
(50) and agitator shaft (6) is as follows:
1. Raise the agitator out of the drum.
2. Remove the plain bearing (53) from the agitator
shaft (6), and clean it.
3. Detach any attachments from the siphon tube, and
flush the siphon tube.
4. Loosen the retaining nut (52), and slowly lift the
siphon tube (50) out of the agitator.
5. Clean the inside and outside of the siphon tube (50),
flush the inside of the agitator shaft (6), and clean
the agitator blades (28) and the outside of the shaft.
6. Reassemble the siphon tube by doing the reverse of
steps 2 through 4.

Servicing the Gear Reducer
You may want to have the Bearing Replacement Kit on
hand before you begin this procedure. To order a
Bearing Replacement Kit, order Part No. 238251.
NOTE: Bearing removal and installation instructions are
included with Part No. 238251.
Disassembling
The following procedure does not require that you
remove the agitator from the drum of material:
1. If your agitator has a siphon kit, do steps 2 through
4 in Cleaning an Agitator with a Siphon Kit on
page 11. If your agitator does not have a siphon kit,
proceed to step 2 below.
2. Raise/support the drum cover above the drum high
enough so that you can reach the underside of it.
3. Remove the three hex head screws (25) that hold
the agitator to the drum cover.
4. Raise the agitator housing 4 to 6 in. (100 to 150 mm)
above the drum cover, and support it at that height
with blocks.
5. Tightly grip the agitator shaft with a clamp to prevent
the shaft from falling into the drum.
6. Remove the two short bolts (11) and the two long
bolts (19) that hold the upper housing (8) and the
lower housing (13) together. Carefully lifting straight
up, lift the upper housing off of the lower housing.
7. Turn the large gear (10) counter-clockwise to
remove it from the agitator shaft, and lift the pinion/
gear assembly (3, 16) out of the lower housing.
NOTE: Before you do step 8, check to be sure the
agitator shaft is well secured. See step 5.
8. Turn the 50 mm nut (26) counter-clockwise to
remove it from the agitator shaft.
9. Carefully lift the lower housing (13) off of the agitator
shaft.
