OWNER’S MANUAL 9

The operation of the Hudson Six follows standard practice in many respects;

however, even those accustomed to Hudson products may refresh their memories

The clutch is disengaged in the conventional manner by depressing the left foot

pedal to release the engine drive from the transmission. Automatic clutch control

is available and the control button is located as shown in Figure I. When the

control button is pushed in, the automatic clutch control becomes operative. The

The transmission operation conforms to the standard shift. The clutch must be

disengaged (either by using the pedal or by removing the foot from the accelerator

The "Electric Hand" transmission control, which is available as a factory-

installed option, has a small lever, Figure la, conveniently located just under the

rim of the steering wheel. This lever has five positions arranged in the form of the

letter 1-3 corresponding to the neutral, three forward and reverse positions of the

standard transmission shifting lever. This lever is easily moved to any of the

sary to lift up on the lever and at the same time push forward in order to get into

The control is electrical while the actual shifting is accomplished by vacuum

power from the engine intake manifold. The control is inter-connected with the

ignition switch and a circuit breaker on the clutch pedal, making it necessary to

have the ignition turned on and the clutch pedal depressed (clutch disengaged)

before the system is energized to accomplish a shift of gears. The starter is also

inter-connected with a circuit breaker on the clutch pedal, requiring the clutch to

be disengaged before the engine can be started. This is a safety feature, preventing

the car from being moved should the engine be started while the transmission is

Your Hudson Six has been designed in accordance with the best practices

determined by years of experience and built under the most rigid standards of

precision. Before shipment from our factory, each mechanical unit was supplied

with the proper quantity of correct lubricant to give maximum protection to the

finely finished working parts. In fact, every precaution has been taken to put in

your hands an unexcelled mechanism, properly protected against premature wear.

Extreme care has been exercised in selecting and testing each lubricant used and

there is, therefore, no necessity of replacing any lubricants until the normal

lighter than aluminum and dissipates heat rapidly. The piston is "T" slotted to

pin and one oil control ring below. With this arrangement all of the rings are

located somewhat lower down on the piston, with the result that cooler operating

conditions and better oil control are obtained. The piston is attached to the

operating temperature. To adjust the tappets, remove the engine side cover plates

(right side of engine below intake manifold) and insert a feeler gauge between the

top of the tappet screw and bottom of the valve stem while the engine is running.

The valve tappets should be adjusted to a feeler gauge clearance of .006" on the

intake valves and .008" on the exhaust valves. The tappet screw locking nut should

be tightened securely after adjustment. The tappet clearance is important and

To determine this, remove the spark plug from number one (front) cylinder.

In order to get maximum life from the tires, they should always be inflated to

Due to increased thickness in tire treads, together with higher driving

speeds, faster acceleration and more effective braking, the tread blocks flex

when in contact with the road so that the forward edges of the tread design blocks

wear more rapidly than the rear, giving a sawtooth appearance. This is known as

heel and toe wear and is particularly noticeable on the front tires which are

subjected to braking action only, while in the case of the rear tires the tread wear is

This is a natural wear and can be controlled by reversing the direction of

rotation of the tire. It is recommended that the right and left wheel and tire

assemblies be interchanged when this wear becomes noticeable. Since the

height of the tread block has been reduced by wear, the flexing will be lessened

and this change of position of tires will not only even up the wear but will in

Wheel and tire balance is carefully checked during the process of assembling;

however, this balance may be changed by removal and reinstallation of tires or

by tire tread wear. In order to maintain original stability at high driving speeds,

have wheels and tires rebalanced whenever it is necessary to remove and

reinstall a tire on a wheel, or, if tire changes are not necessary, balance at intervals

of 5,000 miles. This operation can be readily and accurately done by attaching

sliding type balancing weights to the inside rim flange. The proper position of
