Transmission Housing Assembly; Oil Seal Replacement; Lower Bearing Assembly - Maytag Jenn-Air Service Manual

TRANSMISSION HOUSING
ASSEMBLY
The die-cast aluminum transmission hous-
ing has three (3) steel studs and two (2)
locating pins pressed into its upper region.
The studs provide mounting for the crank
lever, crank gear and cluster gear. The
pins properly position the transmission
cover and gasket to the housing.
A steel drive tube with a splined end is
pressed into the bottom ofthe transmis-
sion housing. Two (2) sleeve bearings
have been installed in the upper and lower
I. D. of the drive tube for the drive shaft to
ride in. The lower bearing assembly is
pressed on the drive tube and locates
against a retaining ring which is secured
to the drive tube. An oil seal is installed in
the bottom of the drive tube.
As the studs, locating pins, drive tube, and
sleeve bearings are all press fitted into
position, in the event that any of them fail,
the transmission must be disassembled
and the entire housing assembly must be
replaced.
NOTE:
This does not include the oil seal
or the lower bearing assembly which can
be replaced.
TRANSMISSION HOUSING
ASSEMBLY· DUAL DRIVE
The die-cast aluminum transmission
housing has four studs pressed into its
upper region. The studs provide mount-
ing for the two crank and two cluster
gears. The top cover is threaded into the
lower housing. A sealant is used on the
threads as a gasket material. A steel
drive tube with a splined end is pressed
into the bottom of the transmission hous-
ing. A sleeve bearing is installed in the
lower I. D. of the drive tube. Another
bearing is pressed into the lower housing
above the drive tube. These bearings
provide a path for the drive shaft to ride
in. An oil seal is installed in the bottom of
the drive tube. The oil seal can be re-
placed as a separate part.
Oil Seal Replacement:
The oil seal is located in the splined end
of the drive tube. The seal can be re-
placed without removing or disassem-
bling the transmission, as outlined below:
1. Disconnect the unit from the power
source.
2. Remove the brake assembly to access
the seal.
3. Use a thin, flat bladed screw driver to
carefully pry the old seal out.
4. Place the drive washer (From Tool No.
14242) and the new seal over the seal
protector (Tool No. 12305).
5. Remove the cone shaped end from
the seal protector tool and slide the
tool, drive washer, and new seal over
the drive shaft up to the seal cavity.
6. Slide the transmission seal driver (Tool
No. 14242) over the drive shaft until it
makes contact with the drive washer.
Use the impact sleeve ofthe tool to
"tap" the seal into the end of the drive
tube.
LOWER BEARING ASSEMBLY
The lower bearing assembly consists of a
ball type bearing which has been installed
in an aluminum die-cast housing. The
transmission assembly must be removed
from the washer cabinet before the lower
bearing assembly can be replaced.
