TUB BEARING
The tub bearing is a sintered metal
bearing molded in rubber to fit with the
outer tub. The inner face of the
mounti ng stem tightens down on the
bearing sleeve locking it to the power
unit. The sleeve always turns with the
power unit inside the outer tub bearing
in spin.
To Remove Outer Tub Bearing:
1. Disconnect unit from power source.
2. Remove outer tub.
3. Because of the porcelain tub and
molded retainer, it is not practical to
drive the tub bearing from the tub.
To remove the bearing from the tub,
elevate the tub so that the porcelain
drai n tube clears the floor. This
could be done by placi ng a 2x4 or a
doubled over corner post under the
tub.
4. Apply pressure on the bearing
pushing it from the tub. This can be
done by standing on the bearing.
To Replace Tub Bearing:
1. Turn tub over, starti ng beari ng into
tub cover.
Note: Caution should be exercised
to see that the tub bearing is started
into the tub straight to prevent and
erratic or egg-shaping when seated
in the tub.
2. Press bearing into place by applying
pressure. This may also be done
by
standing on the bearing. To avoid
getting dirt in the bearing, place a
protective cloth over the bearing
before sta ndi ng on
it.
TRANSMISSION - ORBITAL
How it works:
The helical drive mechanism used on
the washer is simple---not requiring a
special device or linkage normally used
to shift the washer from agitation to
spin.
As you look at the following drawings,
remember that the parts shown in dark
(damper, brake housing, brake drum
and outer race of the spin bearing) are
attached to the base and never rotate.
A reversible motor, helical (threaded)
drive shaft and pulley make up the drive
mechanism. The pulley, threaded onto
the helical drive shaft, moves either up
or down the shaft dependent on the
direction it is turned by the drive motor
through a drive belt.
Agitation
With the pUlley (A) being turned clock-
wise as shown in Drawing 1, it moves
down the helical drive shaft (B). As it
rotates down the shaft, a lug (C) on the
pulley comes against drive lug (D)
