After thoroughly flushing the cooling system, the addition of Hudson Rust and
Corrosion Inhibitor to the water will neutralize the action of any cleaning
compound which may not have drained out. It will also prevent corrosion
of the cast iron and other metals in the cooling system.
Hudson Radiator Cleaner and Inhibitor can be obtained from any Authorized
Hudson dealer.
ANTI-FREEZE
Before putting any anti-freeze in the cooling system, it should be thoroughly
cleaned and all hose connections and gaskets checked for leaks.
The types of anti-freeze recommended are: Alcohol, Glycerine, and solutions of
Ethylene Glycol marketed under various trade names.
Solutions containing calcium salts or other ingredients which promote
electrolytic action should be avoided. They will cause serious corrosion of
the solder joints of the radiator. Also avoid the use of solutions containing
glucose or honey, as they will tend to clog the system; and of kerosene or
fuel oil which, when hot, liberate inflammable vapors.
The following table gives the quantities of the recommended solutions
required for protection against freezing at various temperatures
:
CLUTCH
The clutch, Figure 43, is of the oil cushioned type with large, single cork insert plate, and is
driven by friction from the rear face of the steel flywheel and the forward face of the drop-forged
steel pressure plate.
Large coil engaging springs, some with inner springs (except Super Models), exert pressure
between the steel clutch cover and pressure plate to provide adequate frictional pressure for
driving purposes. These springs exert sufficient pressure to prevent slippage under all driving
conditions.
The large cork insert drive plate is fitted with a number of torsional coil springs to prevent
vibration at any speed. A large, heavy-duty throwout bearing is also provided.
Due to the film of lubricant on the frictional surfaces, burning is prevented and wear is
negligible. A bath of Hudsonite Clutch Compound provides constant lubrication for the fric-
tional surfaces, so that after thousands of miles of driving there will be no material change in the
engaging characteristics. The clutch fluid is triple sealed against leakage.
