Assemble the Agitator
1.
Make sure the spacer (10) is in place (see Parts,
page 18). With its larger-I.D. taper facing up, install
the larger pulley (13) and the drive belt (15) through
the agitator housing. See F
2.
Slide the other end of the drive belt over the smaller
pulley (12). The drive belt should not be tight after it
is installed. Make sure the pulleys are aligned, then
secure the small pulley (12) by tightening its
setscrew. Torque setscrew to 45 to 55 in- lbs (5.1 to
6.2 N•m).
3.
Place the bushing (14) into the larger pulley (13).
4.
Install the screws (14a) in the non-threaded holes in
the bushing (14); do not tighten the screws yet.
5.
Place the installation tool (B) on the end of the helix
tube. See F
NOTE: The installation tool (B) is included with
236762, shaft seal kit
6.
Apply PTFE spray lubricant to the top 6 in. (150
mm) of the helix tube (7). While holding the pulley
(13) down, push the helix tube and tool (B) up
through the bottom of the agitator housing (3) until
the tube is flush with the top of the bushing (14).
Then remove the installation tool.
Wedge a screwdriver blade into the gap of the
bushing (14) to spread the bushing while inserting
tube (7).
7.
Torque the three hex-head screws (14a) oppositely
and evenly to 55 to 60 in-lbs (6.2 to 6.8 N•m). See
F
8.
Install the thrust washer (35) flush to the bushing
(14) as shown in Detail B of F
. 10.
9.
Secure the drive belt cover (2) with the eight screws
(27).
10. Apply PTFE spray lubricant to the siphon tube (4)
inlet end only. Install the siphon tube through the top
of the agitator housing (3). See F
11. Install the two socket-head screws (24) and lock-
washers (25) into the top of the siphon cover (6).
Torque the screws oppositely and evenly to 60 to 70
in-lbs (6.8 to 7.9 N•m).
NOTE: The helix tube (7) should move up and down
about 0.05 inch (1.3 mm). If it does not, the bearings
(11) are not fully seated. Push the bearings in until
they are fully seated. See Parts, page 18 for the
location of the bearings.
12. Apply PTFE spray lubricant to the inside lip of the
bearing nut (8), and tighten it onto the helix tube (7).
NOTICE
Use the installation tool (B) to insert the helix tube (7)
through the shaft seal (21) without damaging the seal
lip. See F
. 10. See Parts, page 18, for the location of
the seal.
