6. Removal and Disassembly of LaSalle Transmission
(See Plate 56 for sectional views of first- and second-type transmissions).
The transmission is mounted on the clutch and
flywheel housing and may be removed without
disturbing the clutch after first removing the
propeller shaft. Precaution should be taken
when removing the transmission to keep the clutch
connection assembly in position. This assembly
is loose in the case and, when the transmission is
out of the car it is free to slip out far enough for
the four fingers of the high-speed synchronizing
drum to pull out of the splines in the main shaft.
As long as the transmission is in high gear this
will make no difference because the main shaft
turns with the clutch connection and the fingers
of the synchronizing drum will therefore always
engage with the same splines of the main shaft.
If the transmission is not in high gear, however,
and this should occur, the clutch connection is
free to turn independently of the main shaft and
the fingers might easily engage with a different
set of splines.
Should this occur, the high-speed synchronizing
drum would be rendered inoperative, and it would
be necessary to remove the transmission top cover
to realign the synchronizing drum with the proper
main shaft splines.
For this reason it is extremely important
that the transmission be kept in high gear
whenever removing or installing it in the car.
If it is to remain out of the car for any length of
time a brace should be installed across the face
of the transmission case to hold the clutch connection
in place.
Disassembly of the transmission may be accomplished
as follows:
1. Drain transmission.
2. Remove cover assembly and the two shifter
shaft locking springs.
3. First type transmission—Remove two interlock
plates which operate the shifter forks. (See
insert Plate 56.)
4. Remove shifter shafts and forks, being careful
not to lose the locking balls.
5. Remove universal joint flange and bearing
retainer.
6. Remove countershaft, allowing countershaft
gear assembly to drop to bottom of transmission
housing.
7. Remove snap ring from inner circumference
of the high-speed synchronizing drum and move
clutch connection gear forward as far as possible.
8. Remove main shaft assembly by pulling back
to disengage from clutch connection gear and
taking it out through top of transmission housing.
