To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the washer before servicing.
• Never start the washer with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be •
reconnected to ensure that the washer is properly grounded.

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.
o. Using a right angle needle nose pliers,
remove spring from around lower
transmission tube (located inside brake
assembly), Figure 51.
NOTE: Remove spring by turning in a
COUNTERCLOCKWISE direction (looking from
lower end of input shaft of transmission
assembly).
p. Remove three screws holding brake pads,
rubber sleeves and brake assembly to lower
bearing housing , Figure 51 , then remove
brake assembly and pads off bottom of
transmission assembly.
IMPORTANT: When reinstalling brake assembly,
we recommend replacing three brake pads. DO
NOT replace just worn pads. Apply a small amount
of No. 26594P Silicone Lubricant to both sides of
each brake pad where it will contact brake
assembly.

NOTE: Refer to Figure 51 for assembly sequence.
IMPORTANT: When installing spring, be sure it is
inserted into groove in large splines of lower
transmission tube. Use tool, No. 242P4, for
installing the spring.
q. After brake is installed, put washer through
the following check to make sure brake is
operating properly.
1. Turn off electrical power to washer.
2. Turn drive pulley one complete revo lution
in agitation direction , then push drive pulley
up against brake.
3. Check for a .030 minimum gap between
drive pulley and helix
ramp
surfaces.
IMPORTANT: If gap is less than .030, brake may
not stop washtub from spinning in required seven
seconds because brake will not close properly.
4. Turn on electrical power to washer and start
washer in the final spin.
NOTE: After washtub has been spinning for two
minutes, normal spin speed should be
approximately 580 RPM. If not, the cause could be
dragging brake pads. If problems occur with steps
3 or 4, remove brake assembly and correct
problem.
