Drive Pulley, Helix and Brake

1. Remove outer tub, see Outer Tub" procedure,
steps 1 through 11.
2. Remove screw, washer and helix securing drive
pulley to input shaft and transmission assembly.
3. Lift drive pulley up and off input shaft of transmission
assembly.
NOTE: When reinstalling pulley, place a small amount
of lubricant on top side of the drive pulley that
will be contacting large flat washers. Lubricate
helix ramps and bore with a small amount of
lubricant.
DO NOT OVER LUBRICATE! Excess lubricant
can be thrown into pivot dome area during
normal washer operation. Any lubricant on pivot
dome, base or friction ring will affect washer
operation. This condition will persist until
lubricant is removed.
4. Remove bolts securing brake pads and brake
assembly to "milk-stool" assembly. Remove brake
assembly and pads off bottom of "milk-stool"
To avoid risk of electrical shock, personal injury, or
death, disconnect power to unit before servicing.
assembly.
NOTE: When reinstalling brake assembly, replace all
three brake pads. DO NOT replace worn
pads only. Apply a small amount of silicone
lubricant (WH60X10006) to both sides of each
brake pad where it will contact brake assembly.
DO NOT OVER LUBRICATE! Excess lubricant
can be thrown into pivot dome area during
normal washer operation. Any lubricant on pivot
dome, base or friction ring will affect washer
operation. This condition will persist until
lubricant is removed.
5. After brake is installed, put washer through the
following check to verify brake is operating
properly.
a. Turn off electrical power to washer.
b. Turn drive pulley one complete revolution in
agitation directly, then push drive pulley up
against brake.
c. Check for a .030 (.76 mm) minimum gap
between drive pulley and helix ramp surfaces.
NOTE: If gap is less than .030 (.76 mm), brake
may not stop washtub from spinning in
required seven seconds because brake will
not close properly.
d. Turn on electrical power to washer and start
washer in the final spin operation.
NOTE: After installing complete tub module in
washer and all hoses have been
reconnected, add at least one quart of water
to washtub to lubricate pump seals. Running
a pump without water will ruin the seals.
After washtub has been spinning for two
minutes, normal spin speed should be
427 ± 25 RPM SLOW speed and 640 ± 25
RPM FAST speed on two speed models. If
not, the cause could be dragging brake
pads. If problems occur with steps (c) or (d),
remove brake assembly and correct problem.
