If the basket does not attain full spin
speed, the torque test procedures as
outlined in the following paragraphs
should be performed to determine the
problem.
The torque available to drive the spin
basket is determined by the amount of
drag or resistance presented by the tub
seal and spin bearing, deducted from the
input torque imparted to the transmission
housing assembly by the clutch assem-
bly.
The Following Torque Tests Will Allow a
Problem in the Spin Drive Train to be
Pinpointed:
NOTE:
Before starting these tests, the
washer should be operated in the agita-
tion cycle with hot water for about two
(2) minutes, and then for two
(2)
min-
utes in a spin cycle. This warms up the
transmission oil and the spin drive train
components.
Available Torque
Place a 1/2 inch socket and torque
wrench on the agitator retaining bolt.
Depress the safety spin switch to allow
the washer to operate in the spin cycle,
then while reading the torque allow the
wrench to turn slowly (about 6 R.P.M.)
through a complete 360 degree cycle.
The reading should be between 18 and
25 inch pounds throughout the complete
360 degree rotation of the wrench.
If the torque readings are within these
limits, the washer is performing properly
and any slow spin complaints can be
assumed to have been the result of off-
balance loads.
If the torque reading exceeds 25 inch
pounds, the input torque outlined later
should be checked to determine the
cause. Probable causes are that the drive
shaft is binding in the transmission hous-
ing (drive tube) sleeve bearings, or that
the clutch spring is binding on the drive
shaft hub.
If the available torque reading is less than
20 pounds, follow the procedure for
testing the drag torque.
Drag Torque
Position the washer so the drive pulley
can be accessed, and remove the drive
belt. While holding the transmission to
keep it from turning, manually rotate the
drive pulley counterclockwise
until the
brake stays disengaged.
Make certain
the drive pulley hub shoulder has rotated
fully against the cams in the spin driving
position to ensure the complete disen-
gagement of the brake. Release the
transmission so it is free to turn.
Place a 1/2 inch socket and torque
wrench on the agitator retaining bolt.
Slowly rotate the wrench 360 degrees at
approximately 6 R.P.M. and read the
torque. If the torque reading is over 4
inch pounds, remove the brake stator (as
detailed earlier in this section) and re-
check the drag torque.
Ifthe torque reading is now under 4 inch
pounds, the brake' is binding and should
be repaired.
If the reading is still over 4 inch pounds,
the tub seal and/or spin bearing is bind-
ing and should be replaced.
