Agitation - Maytag Jenn-Air Service Manual

hub is driven in a clockwise direction, the
clutch spring tightens on the two hubs
and becomes a positive drive link be-
tween them. When the drive shaft hub
runs counterclockwise, the clutch spring
relaxes in an override situation. In the
override, or relaxed position the clutch
spring still maintains a drive link between
the two hubs. The override tension, or
torque is used to drive the spin basket.
The anti-backup spring is a clutch type
spring, one end which terminates in an
an extended leg and hook configuration.
The coil portion of the spring is mounted
over the drive pinion hub as previously
described, and the extended leg portion
is fitted with its hooked end secured in a
slotted boss in the transmission housing.
When the drive pinion rotates in a clock-
wise direction, the spring relaxes and
exerts no appreciable force on the drive
pinion. When the drive pinion starts to
revolve counterclockwise, the spring
tightens on the hub of the pinion and
prevents it from turning.
Note: Later models use an anti-backup
cam stop under the crank gear, instead of
the anti-backup spring.
CLUTCH ASSEMBLY· DUAL DRIVE
The clutch assembly consists of the drive
shaft and hub assembly, clutch spring, and
input pinion with gear lock assembly. The
gear lock mechanism is part of the input
pinion. The drive shaft serves only as a
bearing surface for the drive pinion to
revolve on. No direct drive is imparted
from the shaft directly to the pinion. The
inside diameter of the clutch spring is
designed so that when the drive shaft is
driven in a clockwise direction, the clutch
spring tightens on the two hubs and be-
comes a positive link between them.
When the drive shaft hub runs counter-
clockwise, the clutch spring relaxes in an
override situation. In the override, or
relaxed position, the clutch spring still
maintains a drive link between the two
hubs. The override tension, or torque, is
used to drive the spin basket. The gear
lock mechanism consists of two "wings"
that project out from the input pinion.
When the drive pinion rotates in a clock-
wise direction, the gear lock mechanism
exerts no force on the input pinion.
When the input pinion starts to revolve
counterclockwise, the "wings" drop into
detents in the lower housing preventing
the pinion from turning.
AGITATION
The clockwise (agitate) rotation of the
drive shaft and the hub assembly is trans-
mitted to the drive pinion by the clutch
spring. The drive pinion meshes with the
cluster gear which, in turn, meshes with
the crank gear. The circular motion of the
crank gear is converted to the oscillating
action of the agitator shaft by a linkage
arrangement which consists of a connect-
ing rod that mounts over a stud on the
crank gear, and a lever assembly. Any
tendency of the transmission housing to
turn or "creep" is prevented by the en-
gaged brake assembly located on the
under side of the suspension housing.
AGITATION· DUAL DRIVE
The clockwise (agitate) rotation ofthe
drive shaft and hub assembly is transmit-
ted to the input pinion by the clutch
spring. The input pinion meshes with the
dual cluster gears which, in turn, mesh
with the dual crank gears. The circular
motion of the dual crank gears is con-
