(23) Lower the transmission jack and remove the
transmission and converter assembly.
(24) To remove the converter assembly, remove
the "C" clamp from the edge of the bell housing, then
carefully slide the assembly out of the transmission.
STARTER RING GEAR REPLACEMENT
The starter ring gear is mounted directly on the
outer diameter of the torque converter front cover.
With the torque converter removed from the vehicle,
replacement of the gear is as follows:
Removing Ring Gear
(1) Cut through the weld material at the rear side
of ring gear with a hack saw or grinding wheel (Fig.
62). Be careful not to cut or grind into the front cover
stamping.
(2).Scribe a heavy line on the front cover next to
the front face of the ring gear to aid in locating the
new gear.
(3) Support the converter with the four lug faces
resting on blocks of wood.
The converter must not
rest on the front cover hub during this operation.
Us-
ing a blunt chisel or drift and hammer, tap downward
on the ring gear near the welded areas to break any
remaining weld material (Fig. 62). Tap around the
ring gear until it comes off the converter.
(4) Smooth off the weld areas on the cover with a
file.
Installing Ring Gear
Any of the following methods may be used to heat
and expand the starter ring gear for installation on
the converter:
Oven:
Place the ring gear in Oven C-794 and
set
the temperature at 200 degrees F. Allow the ring gear
to remain in the oven for 15 to 20 minutes.
Boiling Water:
Place the ring gear in a shallow con-

tainer, add water, and heat for approximately eight
minutes after the water has come to a boil.
Steam:
Place the ring gear on a flat surface and
direct a steam flow around the gear for approximately
two minutes.
Flame:
Place the ring gear squarely on a flat sur-
face. Using a medium size tip, direct a slow flame
evenly around the inner rim of the gear.
Do not ap-
ply flame to the gear teeth.
Place a few drops of wa-
ter on the face of gear at intervals during the heating
process. When the gear is hot enough to just boil the
water, installation of the gear on the torque converter
can be made.
(1) After the ring gear is expanded by heating,
place the gear in position on the converter front cov-
er. Tap the gear on the cover evenly with a plastic or
rawhide mallet until the face of the gear is even with
the scribed line (made during removal) on the front
cover. Make sure the gear is even with the scribed
line around the full circumference of the front cover.
(2)
Reweld the ring gear to the torque converter
front cover, being careful to place, as nearly as pos-
sible, the same amount of weld material in exactly
the same location as was used in the original weld.
This is necessary in order to maintain proper balance
of the unit. Place the welds alternately on opposite
sides of the converter to minimize distortion.
(3) The following suggestions are offered as an aid
in making the weld:
a.
Do not
gas weld.
b.
Use a D.C. welder that is set at straight polarity
or an A.C. welder
if
the proper electrode is available.
c. Use a YS inch diameter welding rod, and a weld-
ing current of 80 to 125 amps.
d. Direct the arc at the intersection of the gear
and front cover from an angle of 45 degrees from
the rear face of the gear.
(4) Inspect the gear teeth and remove all nicks
where metal is raised, weld metal splatter, etc., in or-
der to ensure quiet starter operation.
FLUSHING THE TORQUE CONVERTER
In the event that any part has failed in the trans-
mission, the torque converter should be flushed to in-
sure that fine metal particles are not later transferred
back into the reconditioned transmission.
The torque converter
must be removed
from the
vehicle for flushing, as the converter should never be
rotated by the starter with the transmission removed.
(1) Place the torque converter in an upright posi-
tion and pour two quarts of new clean solvent or
kerosene into the converter through the impeller hub.
(2)
Turn and shake the converter so as to swirl the
solvent through the internal parts. Turning the tur-
bine and stator with the transmission input and reac-
tion shafts will aid in dislodging foreign material.
