IMPORTANT: DO NOT apply any lubricant to surface of snubber pad and isolator assembly or pivot dome. Any lubricant on pivot dome or isolator will cause premature tripping of the out-of-balance switch.

b. Clean surface of pivot dome. Then carefully

place tub module back into washer making sure pivot dome is positioned properly in dome recess of washer base.

NOTE: Make sure the word “FRONT” (on outer tub) is facing toward front of washer.

c. Use No. 321P4 Spring Hook Tool and starting

with rear springs, hook seven centering springs into lower edge of outer tub skirt. Refer to Figure 54.

IMPORTANT: When installing centering springs, make sure spring hook is fully seated in hole in tub skirt. Refer to Figure 54.

d. Connect hose to bottom of outer tub, tighten

hose clamp.

e. Reconnect idler spring to clip on motor

mounting bracket.

f. Place drive belt on motor pulley, reach around

right side of motor, starting with belt on right side of large pulley, run belt onto large pulley.

g. Route the pressure hose as shown in Figure 62.

Then route pressure hose back up through hole in cabinet top.

h. Reconnect filler hose to tub cover. Refer to

Figure 48.

NOTE: When reinstalling filler hose, white line on hose that connects to tub cover must be aligned with line located on top side of outer tub cover. Refer to Figure 48. Make sure hose is in its natural position (not kinked or twisted). If it is not, loosen hose clamp and straighten hose.
