UPPER SPIN BEARING
The spin bearing is installed in a cavity on
the underside of the bearing and seal
housing and is further secured in place by
the inner diameter of the tub support.
SPIN BEARING REPLACEMENT
1. Disconnect power to the unit.
2. Remove the upper bearing and seal hous­
ing and the tub support as previously de­
scribed.
3. Remove the seal body from the housing
cavity.
4. Press the spin bearing out of the cavity
from the opposite side of the housing.
5. When installing the replacement bearing
into the housing cavity, be sure to press
against the outer race of the bearing to
avoid damage to the bearing shield and
causing premature failure.
DRIVE PULLEY AND CAMS
The drive pulley and cam is located below
the brake assembly on the drive shaft.
Models are equipped with a plastic drive
pulley which has the upper cam molded
onto the bottom of the hub. The purpose of
the pulley and cam arrangement is to drive
the clutch assembly during the agitate and
spin cycle, and to disengage the brake as­
sembly during the spin cycle.
The drive pulley slips over the drive shaft and
rests against a series of washers, a thrust
bearing, and a large washer type spacer. The
spacer locates against the bottom of the
brake rotor and lining assembly. (See the
illustration on page 7-6.)
The lower cam slips over the end of the drive
shaft where splines formed in the cam en­
gage with mating splines on the drive shaft
end. This imparts a direct drive from the cam
to the drive shaft. A shoulder molded on the
bottom of the pulley hub engages "dogs"
formed on the sides of the lower cam, and
will drive it and the drive shaft in either di­
rection.
A washer and retaining ring secure the pul­
ley and cam on the drive shaft. A plastic dust
cap snaps to the underside of the pulley to
keep the cam surfaces clean.
OPERATION
When the drive pulley rotates CLOCKWISE,
the upper and lower cams are designed to
nest together which allows the drive pulley
to remain in position on the drive shaft. The
break remains engaged and the drive pulley
will turn the lower cam and drive the shaft
to cause the transmission to agitate.
When the drive pulley rotates COUNTER­
CLOCKWISE, the upper cam and pulley ride
up the lower cam approximately 3/16 of an
inch before the driving shoulders on the pul­
ley hub engage the "dogs" on the lower cam.
This causes the top of the pulley hub to push
against the spacer which compresses the
brake spring and lifts the brake rotor and lin­
ing assembly off the brake stator. The brake
is disengaged and the pulley will turn the
lower cam and drive shaft to cause the trans­
mission to spin.
