Disassembly Procedures
RS3100007 Rev. 0 28
WARNING !
Weldment and Bearing Assembly
1. Remove outer tub, see Outer Tub” procedure,
steps 1 through 11.
2. Remove screw, washer and helix holding 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 No. 03200P 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 No. 03200P Lubricant.
DO NOT OVER LUBRICATE! Excess lubricant
can be thrown into pivot dome area during
normal washer operation. Any lubricant on pivot
dome, hose 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 weldment assembly. Remove brake
assembly and pads off bottom of weldment
assembly.
NOTE: When reinstalling brake assembly, replace all
three brake pads. DO NOT replace worn pads
only. Apply a small amount of No. 265494P
Silicone Lubricant 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 offset 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 direction, 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.
NOTE: After installing complete tub module in washer
and all hoses have been reconnected, add at
least a 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 one and two speed models; or
473 ± 25 RPM on SLOW speed and
710 ± 25 RPM on FAST speed on some two
speed models and all three speed models.
Three speed models never spin on the lowest
speeds. If not, the cause could be dragging
brake pads. If problems occur with steps (c) or
(d), remove brake assembly and correct
problem.
6. Remove bolts securing counterweight and each
support leg to outer tub. Lift transmission, weldment
assembly and counterweight off tub.
NOTE: It may be necessary to tap lightly on the
weldment assembly to loosen it from
transmission tube.
Torque screws between 100 to 150 inch-
pounds.
7. Remove screws and washers securing
counterweight to leg on weldment assembly.
8. Reverse procedure to reassemble.
