IMPORTANT: Use care when removing old water
seal so as not to damage tub flange or porcelain.
NOTE: When reinstalling or replacing outer tub,
we recommend installing a new No. 495P3A Hub
and Seal Kit. Refer to Paragraph 38.
While holding idler lever, reach in and around right
side of motor and run belt off right side of pulley.
We recommend that before removing or reinstalling
complete tub module assembly, you unhook idler
spring and move idler lever out of the way. This will
prevent the possibility of idler lever or pulley
damage.
n. Using No. 321P4 Spring Hook Tool, unhook
seven centering springs from lower edge of
outer tub. Refer to Figure 39.
IMPORTANT: Mark the word “FRONT” on front
side of outer tub so complete tub module can be
reinstalled in same position.
o. Disconnect hose from bottom of outer tub.
IMPORTANT: Some water will always remain in
outer tub. Therefore, before removing hose from
pump, pinch off or drain hose to prevent water
spillage.
p. Remove pressure hose from pressure switch.
q. Grasp outer tub and lift complete tub assembly
(with transmission, balance ring and pivot
dome attached) straight up and out of washer
cabinet.
r. Turn outer tub upside-down and set on
protective padding. Refer to Figure 40.
s. Remove screw, washer and helix holding drive
pulley to input shaft of transmission assembly.
Refer to Figure 41.
t. Lift drive pulley up and out from between tub
support legs.
NOTE: When reinstalling pulley, place a small
amount of lubricant to top side of drive pulley that
will be contacting the large flat washer. Lubricate
helix ramps with a small amount of lubricant. Refer
to Figure 42.
IMPORTANT: DO NOT OVER LUBRICATE!
Excess lubricant can be thrown into pivot dome
area during normal washer operation. Any
lubricant on pivot dome or snubber pad and
isolator assembly will cause premature tripping of
the out-of-balance switch. This condition will
persist until lubricant is removed.
u. Through Serial No. 9606029040 - Using a
right angle needle nose pliers, remove spring
from around lower transmission tube (located
inside brake assembly). Refer to Figure 42.
NOTE: Remove spring by turning in a
counterclockwise direction (looking at bottom end of
shaft).
IMPORTANT: When reinstalling spring, make sure
it is inserted into groove in large spline of
transmission tube. Use spring tool, No. 242P4, when
installing spring.
v. Remove screws and lockwashers holding each
support leg to outer tub. Refer to Figure 42,
then lift pivot dome, brake assembly and lower
bearing housing off transmission tube.
NOTE: It may be necessary to tap lightly on bearing
housing to loosen it from transmission tube.
IMPORTANT: When installing lower bearing
housing, pivot dome and brake assembly, apply No.
27604P Anti-Seize Compound to area of
transmission tube that will be contacting bearing.
Refer to Figure 43.
To prevent porcelain damage, leg plates must be
installed on outer tub flange when reinstalling
support legs. (Plate must be installed on outside of
tub flange.) Do not overtighten screws as this could
cause stripping or porcelain damage. Torque screws
between 90 to 130 inch-pounds (10.3 to 14.87 Nm).
w. Remove four screws and lockwashers holding
transmission assembly to balance ring. Refer to
Figure 43, then lift transmission assembly
