Transmission; Clutch; Rear Axle - Cadillac 1937 LaSalle VVI Information

ransmission
The LaSalle transmission incorporates synchronized gear
shifting, and quiet operation in all speeds. Synchroniza-
tion is applied to all shifts into high or second gear, for
maximum convenience and safety.
The only attention ordinarily required by the transmission
is lubrication at 3,000 mile intervals. The correct grade of
lubricant is essential to long life and continued quiet opera-
tion. Lubricants meeting the specification SAt-90-EP can
be used the year round.
Clutch
The clutch is of the single plate type, having one driven
disc faced on both sides with long wearing friction material,
cushioned with a special metal segment to assure smooth
engagement.
To provide maximum ease of control, small centrifugal
weights integral with the clutch release levers are used to
increase the spring pressure as the engine speed increases,
giving low pedal pressure at low engine speeds, yet securing
adequate engagement pressure at high speeds.
The only at-
tention or adjust-
ment ordinar-
ily required by
the clutch is per-
iodic adjustment
of the c l u t c h
pedal to allow %
to 1J^ inches
free travel before
the clutch actu-
ally starts to en-
gage. This can
be done by turn-
ing the adjusting
nut on the pedal
rod.
ear Axle
The LaSalle rear axle is of exceptionally rugged design
and construction to assure long life and quiet operation. A
strong cylindrical type gear mount maintains accurate gear
adjustment over a long period of use. The gear ratio is 3.92
to
1.
The propeller shaft incorporates two needle bearing uni-
versal joints, which are packed with lubricant and sealed.
Sealed ball bearings are used at the rear wheels, and they
require no readjustment or other attention. Because of these
features, the only regular servicing required by the rear axle
is lubrication of the gears.
Special Hypoid Lubricant, available at Authorized Service
Stations, must be used in the rear axle. This lubricant is of
the proper viscosity for year round use, although it should
be drained and replaced with fresh lubricant every 6,000
miles. No other lubricant can be safely used. (See page 47.)
If, after a long period of use, the rear axle gears require
adjustment or other servicing, a complete new gear assembly
can be secured on an exchange basis at moderate cost. This
exchange is handled through your Authorized Service Station.
