If the reading is still over 4 inch pounds,
the tub seal and/or spin bearing is bind-
ing and should be replaced.
If the available torque reading is below
18 inch pounds and the drag torque
reading is not over 4 inch pounds, follow
the procedure for checking the clutch
assembly as to its input torque.
Input Torque
NOTE: It will be observed that the
readings used to check the input torque
are slightly lower than the readings used
to check the available torque. The rea-
son for this is when the brake is disen-
gaged, as in checking the available
torque, the compressed brake spring
exerts a downward force on the bottom
of the clutch hub and thrust washers.
This keeps the clutch spring from slip-
ping quite as readily as in checking the
input torque where the brake is engaged
and the downward force on the clutch
hub is minimized.
To check the input torque, remove the
drive pulley and position the washer so
the scale on the torque wrench can be
read when it is placed on the input (drive)
shaft. Attach the torque wrench adapter
firmly to the shaft, place the wrench in
the adapter and slowly rotate the wrench
in a counterclockwise direction. A prop-
erly operating clutch assembly will have a
torque reading between 17 and 20 inch
pounds.
If the input torque is less than 17 inch
pounds, the clutch assembly is defective
and must be repaired or replaced.
If the input torque exceeds 20 inch
pounds, remove the clutch assembly
from the transmission. Secure the drive
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.
If the torque reading is now under 4 inch
pounds, the brake is binding and should
be repaired.
