62 GENERAL CARE
cleaning may be determined by inspection. Its necessity is indicated by
lack of capacity, excessive evaporation of the acid solution and excessive
heating when charging. If a battery is in need of cleaning or repairs, it is
best to communicate with a Cadillac distributor or dealer or with the nearest
Exide depot, who will advise you where to ship the battery. Do not ship
batteries without receiving instructions.
Exide Depots and Sales Offices
The Electric Storage Battery Company, whose general offices and works
are at Alleghany Avenue and 19th Street, Philadelphia, Pa., has service
stations in towns of any considerable size where battery repair work is done,
as well as sales offices and Exide battery depots in a number of the larger
cities of the country, where complete assembled batteries and repair parts
are carried in stock. For the location of the nearest Exide depot or service
station, write the local Cadillac distributor or dealer, or, if preferred, the
Electric Storage Battery Company, at Philadelphia.
TRANSMISSION AND CLUTCH
TRANSMISSION
General Description
The transmission is in unit with the engine, and is of the selective type
of sliding gear. The gear changes are accomplished by the movement of a
hand lever at the driver's right (see Figure 1, also under "Gear Shifting,"
page 10).
When traveling in high gear, power from the engine is transmitted through
the transmission without passing through any of the transmission gears.
Power is transmitted through transmission gears when the car is operated
in intermediate, low, or reverse gear.
Changes of gear must never be attempted without first disengaging the
clutch by holding down on the clutch pedal.
Lubrication
The transmission case should always contain lubricant enough to bring
the level up to the filler plug in the right-hand side of the case. The level
should be inspected at least every 2,000 miles, and lubricant added if
necessary.
At the end of every 4,000 miles the transmission case should be thor-
oughly drained and refilled with fresh lubricant.
Cadillac Rear Axle and Transmission Lubricant is recommended for the
transmission. In its absence steam cylinder oil mixed with gun grease may
be used. The consistency of the mixture should be such that the mixture
will flow easily at temperatures of from 60° to 70° Fahrenheit.
GENERAL CARE 63
CLUTCH
General Description
The main clutch is of the multiple disc dry plate type. The driving
discs are covered on both sides with a friction material composed largely
of asbestos, and are driven by gear teeth in a clutch ring bolted to the fly
wheel of the engine.
The driven discs are not covered. These discs are carried on a clutch
hub and drive the clutch hub through keys. The clutch hub in turn drives
the transmission shaft.
When the clutch is engaged by allowing
the clutch pedal to come toward you, the clutch
spring forces all of the discs together.
The resulting friction between the driving
and driven discs drives the transmission shaft
and the car when the transmission control
lever is in other than neutral position.
The clutch pedal should be adjusted occa-
sionally to compensate for wear on the facings
of the clutch discs. This adjustment is ex-
plained below under "Adjustment of Clutch
Pedal Clearance."
Adjustment of Clutch Pedal Clearance
After the car has been run for some time it may be found that the fac-
ings on the clutch discs have become compressed or worn to some extent
and that consequently the clutch pedal strikes the stop screw before the
clutch is fully engaged. When this condition exists a readjustment may be
made as follows:
Remove the pin "T," Fig. 25, and unscrew the yoke "S," which is
threaded on the rod "O," so that when the pin " T " is replaced the clutch
pedal has a movement back and forth of one and one-quarter inches without
starting to release the clutch. Secure the pin " T " with a cotter pin and
tighten the lock nut "R."
