If the transmission has been totally disassembled, the jack shaft "N"
(Fig. 16) should be positioned, so that the sides of the teeth of the gear "A"
are flush with the sides of the teeth of the gear "I" before the above adjust- .
ment is made. Adjustments are provided at "G"-"G" by which the jack shaft
may be adjusted endwise.

ADJUSTMENT OF TRANSMISSION GEARS.
The teeth of the transmission gears should mesh so that the sides of
the two gears in mesh will be flush, or at least not to exceed 1/16" of being
flush. These gears are not liable to require readjustment.
If for any reason it becomes necessary to alter the position of the gears
in order to make them mesh properly, proceed as follows:
Move the control lever to the low gear position, being careful not to
move it beyond the low gear position. Then loosen the lock nut "K" (Fig.
17) and turn the adjusting nut "L," thereby moving the shaft "M" endwise,
until the sides of the teeth of the two gears in mesh are flush. Then tighten
the lock nut "K."
The main clutch is of the multiple disc dry plate type.
The driving discs "A" are covered on both sides with a friction material,
composed largely of asbestos, and are driven by six keys in the clutch ring
"H" which is bolted to the engine fly-wheel "G."
The driven discs "B" are not covered. These discs are carried on the
clutch hub "E" and drive it through six keys on the hub. The clutch hub
is keyed to the transmission shaft "F."
When the clutch is engaged by allowing the clutch pedal to come towards
you, the spring "C" forces all of the discs together. The resulting friction
between the discs "A" and "B" drives the transmission shaft "F" and the
car, when the transmission control lever is in other than the neutral position
