With the car on level ground and the engine
off, climb up behind the wheel. Notice the hand lever on the
floor to your left, the two levers on the steering column
beneath the steering wheel, and the three pedals on the floor.
Let's start with the hand lever. All the way back it sets the
rear wheel parking/emergency brakes and puts the transmission in
neutral. Half-way released it maintains neutral, and fully
released it engages the planetary transmission in high gear.
Feel it a few times, notice that it holds the left pedal in
neutral mid-position, then release it, and notice that the left
pedal is all the way up.
Next, the lever to the left beneath the steering wheel is the
spark adjust advance/retard from before top dead center ignition
to after top dead center. To retard the spark it is moved up, to
advance the spark it is moved down. The Model T is always
started in the retard position, as it was designed to be started
by hand cranking. Unless it is retarded the engine can and will
KICK BACK and do damage to hands, wrists and arms. NEVER crank
it except in the retard position. After the engine is running,
the lever can be moved down to advance the ignition until the
engine chuckles smoothly, and when rolling to get the best
performance.
Controls of the
Ford Model T
The lever to the right is the throttle lever, there is no foot
pedal like a modern car. Up is idle speed, down is as fast as it
will go. Maximum performance in a Model T is like with a mule,
with both ears laid back.
Next, the foot pedals on the floorboard -
The left foot pedal changes your forward gear ratios, up is
high, down is low. The Model T has just those two forward
ratios, high gear and low gear. Midway between high and low is
the neutral "out of gear" position of the left pedal.
To engage first gear, let the handbrake lever off and push the
pedal all the way down until it becomes HARD. Pull the handbrake
up and feel how the lever holds neutral position on the gear
pedal.
The center pedal is for reverse gear engagement, but either the
hand lever or the left pedal must be in neutral position before
engagement, or the engine will stall. All the way down HARD is
reverse position.
The right pedal is the brake. It engages a band around a braking
drum in the transmission, operating in the engine oil bath.
Therefore, to avoid burning off the oil due to friction heat,
and wearing out the band quickly, apply the brake in relatively
short duration thrusts to allow the oil to wash and continue
lubricating and cooling it.
Note: The Ford Model T only applies braking to the rear
wheels.
Braking by right pedal is via the driveline to the rear wheels
only, does not actuate the rear drum brakes, and can cause
dangerous skids in slick road conditions, as the differential
will allow one wheel to spin forward and the other backward.
Therefore, in slick conditions, use the hand lever to apply
braking to the rear drum brakes.
Get the feel of the controls, they will become familiar quickly.
Starting the Engine
1. Raise the right side of the engine hood and check that the
engine oil level is adequate, within the limits prescribed. This
is done by opening the lower petcock at the rear of the engine.
If it does not flow, close the lower petcock, open the upper
petcock and add oil until oil flows from the upper petcock.
Close the upper petcock, lower and latch the hood.
2. Remove the radiator cap and top off the radiator with fresh
water and/or antifreeze solution in freezing weather. A 30-40%
methanol (wood alcohol)/ water solution may be used, but a 50%
ethylene glycol/water solution is recommended for all seasons.
Please observe that the hand crank is located in the center of
the car below the radiator. To crank the engine, one must stand
in the path the car will take if the engine starts while in
gear. The car is NOT OUT OF GEAR UNLESS the Emergency
brake/neutral lever is all the way back and the rear brakes set.
This must be done FIRST, or you will get run over by your own
car should the engine start, MOST EMBARRASSING!
NEXT, move the spark advance/retard lever all the way up to
retard position. Move the throttle lever down approximately ? of
the quadrant.
Observe that the Magneto/OFF/Battery Switch (or key) on the coil
box or dash panel is in the OFF position. The Model T may be
started in either Magneto or Battery position, usually in
Battery position unless the battery has lost charge.
Observe the wire ring at the lower left corner of the radiator
as you face the car. This is the pull wire of the hand choke.
PULL IT OUT.
With the switch (or key) OFF, push the crank in and crank the
engine over one or two turns, finishing by coming up against
compression and just past.
Turn the Magneto/OFF/Battery switch to Battery. The coils will
buzz, and sometimes the engine will start without further
cranking, especially if warm. If it doesn't, the engine must be
cranked through one more cycle of intake/compression. Do this
carefully with your LEFT hand, pulling up ONLY by ratcheting the
crank as necessary. Do not grip the crank handle but cup it in
the palm of the hand with the thumb on the same side of the
handle as the fingers. As the cylinder begins to come up on
compression, ratchet the crank down to the bottom. Now pull up
swiftly, and the engine will start. If not, repeat the process.
WARNING!
NEVER start the car with your right
hand. If the engine were to misfire or kick back, you would
likely suffer a broken wrist and/or arm. The right hand may be
used for priming the engine, as you need your left hand free to
operate the choke, but when ever the ignition switch is ON, you
MUST use your left hand. again, do not grip the crank handle but
cup it in the palm of the hand with the thumb on the same side
of the handle as the fingers.

In cold weather the choke may need to be left out until the
engine warms. It may be released (or set) from the driver's seat
by pushing down the choke/carburetor adjust knob to the right
side of the dash panel.
Speed up the engine with the throttle lever,
advance the ignition with the advance/retard lever about
half-way, then return the engine speed to an idle. It will now
chuckle over smoothly at about 400 rpm.
Making the Car Move...
Taking what you have learned so far in both hands and both feet,
hold the high/low gear pedal half way down in neutral position
with your left foot and let the handbrake off, holding the car
in position with the right foot on the brake pedal. Increase the
engine revs and gently press the gear pedal down, letting off
the brake pedal. The car will move forward. Hold the gear pedal
down firmly and increase engine revs up to near full speed, this
should only take a couple of seconds. Let the gear pedal off to
engage top gear, slowing the engine with the throttle lever to
get a smooth gear change. (This will take a little practice to
perfect, but there is no cause for fear of crashing gears. The
transmission bands may be slipped by relaxing foot pedal
pressure to control smoothness of engagement.)
Stopping
Having learned how to get the car in motion, now might be an
opportune moment to learn how to stop it! One of the odd things
about bowling along in a T is how you have nothing to do with
your feet, unlike an ordinary car where you are always on the
accelerator pedal. I like to have my right foot beside the brake
pedal so it is ready to transfer onto the brake as you would
with standard controls. So far the right foot is doing the same
as it would in normal driving, it is the left foot which
(provided it is not an old dog) must be taught a new trick. In
its simplest form this consists of just holding the gear pedal
half way down to get neutral as you come to a halt. One of the
nice things about driving Fords of this age is that they can
start and stop with reasonable speed so as to keep up with
modern traffic, extra braking being easily obtainable by pushing
the gear pedal further down to engage low gear. It follows that
having engaged the gear it has to be disengaged to actually come
to a stop. After some practice it becomes second nature to ease
the gear pedal down and up again as you roll to a halt.
Hill Climbing
A Model T Ford will climb an 8% (1 in 12) gradient in top gear
with full throttle, and will come down it in top gear with no
throttle and no brake application. They can safely negotiate 20%
or more grades in low range, so hills should hold no fears for
Model T Ford owners, but a few words of advice at this point.
Going up is relatively easy, just give the Lizzie full throttle
and retard the ignition a little as the speed falls, and she
should slog up the hill in fine style provided there is a
reasonable amount of fuel in the tank. The T needs about a
quarter tank full to climb a 20% grade, as the gravity feed
system becomes less effective the steeper the grade. It was
common practice, if the grade was too steep and the engine
starved for fuel, to back a T over the grade.
As a general rule going down hills should be done at about the
same speed as going up. However, the real secret is to
successfully use engine compression to slow the car speed on a
hill. Move the throttle lever up to minimum or to a setting
which will maintain a safe down-grade speed. As there is no
return spring on the throttle lever it can be set as slow as
necessary, and will hold position. If braking is still
necessary, let the pressure off the pedal every so often to
prevent burning the linings. Reverse pedal can also be used to
brake for added effectiveness if needed. (see "Saving Your
Bands" below).
If you need to stop on a steep grade, use low gear as you brake,
but be careful to not over speed the engine in low gear. Be
aware that there is no engine braking, if the left foot pedal is
held in neutral between high and low gear positions. Jamming all
three pedals down will stall the engine and skid the rear tires,
not an acceptable solution to emergency braking, except on dry
pavement, and even then not recommended. NEGOTIATE HILLS AT SAFE
SPEEDS, do not allow the car to "Roll Out."
Steering
The steering on the Ford Model T is very direct and lively by
today's standards. It is a direct ratio of the sun/planet gears
in the steering column below the steering wheel. Direct steering
is common with most cars of this age. The Ford, with a
transverse front spring, is subject to "twitching" over lumps
and bumps in the road. As the front wheel hits an obstruction it
causes the front axle to move sideways on its shackles,
"twitching" the steering. You can fight the steering every time
it jumps, holding the wheel with a vice like grip in which case
you will have arm ache after a twenty minute drive, or you can
relax your grip and let the steering wheel twitch rather than
the road wheels.
It goes without saying that there should be no slack or play in
the steering linkage. The camber, caster and toe-in of the front
axle should be checked carefully for correct steering geometry.
Drawbacks of
a Two Speed Gearbox
In normal driving the two speed pedal operated gear change works
very well. It gives a very simple easy gear change enabling you
to nip up and down the gears with a minimum of effort. However
it does have its drawbacks. The obvious one is the large gap
between the gears, there are some circumstances when bottom gear
is too low and top is too high. A Ruckstell two speed rear axle
alleviates this to some extent.
Places where you may find difficulty are:
1. Changing up a gear on hills.
2. Going into junctions or roundabouts (traffic circles) where
top gear is too fast.
Or
3. Going over rough ground or grass.
All that can be done is to grind along in low gear until top
gear can be used again. The only other answer is to install an
auxiliary gear such as the Ruckstell two speed rear axle. In
practice a bit of coasting around obstructions and then with a
quick burst of low gear before going back into high again will
negotiate most of these situations with ease.
Maneuvering a Model T
Maneuvering the Model T can really separate the men from the
boys. It is suggested that the novice driver avoid tight
situations until some practice has been obtained.
To reverse hold the left gear pedal half way down in neutral
with the left foot, gently press the reverse pedal to go
backwards with the right foot. Relax the pressure on the reverse
pedal and press the brake with the right foot when you want to
stop. Alternatively, apply pressure to the left pedal to brake
bringing the car to a stop. This can also be accomplished by use
of the hand lever to place the left pedal in neutral, so that
when the reverse pedal is released, the brake pedal can be
applied. We only have two feet to operate 3 pedals.
The reason why instant action may be needed is this, it takes
some time for a driver used to ordinary controls to come to
terms with pressing pedals to go rather than stop. In a second
you can find that the car is going too fast and the harder you
press the pedal the faster it goes. If you keep the right foot
ready on the right brake pedal, disaster can be averted. This is
the only pedal that will hold the car stationary.
A Three Point Turn
Once the finer points of maneuvering have been mastered, the
Model T three point turn-around much loved by the likes of
Laurel and Hardy can be tried. This consists of getting an
instant reverse by pressing the reverse pedal when going forward
and then doing the same thing with the low gear pedal when going
back to give a second instant change of direction. This should
be done with some care so as not to strain the transmission.
Other drivers are mystified as to how this is done without any
grappling of gear levers.
The Transmission
The Ford Model T planetary transmission has three bands, one for
low gear, one for reverse and one for the brake. These bands
need to be changed from time to time, but if you can wear them
all out together you will get the longest time between band
changes. The brake band has the hardest life while the reverse
band gets relatively little use. The wear can be equalized by
using reverse pedal for some of the braking. Use reverse first
to slow the car, then slide the foot across onto the brake pedal
to come to a halt.
These bands and gearing run in the engine crankcase oil. If they
are allowed to slip too much the oil is burned off and the
lining of the band will be worn very quickly. To avoid this
always hold the low gear pedal down firmly and do your braking
in relatively short bursts releasing the pressure to allow the
oil back round the lining.
The transmission is an Epicyclic or
Planetary gear transmission. Using 3 triple gears rotating
around a driven gear, like the planets orbiting the sun.
Because the different gear teeth are always in mesh, it is not
possible to "crash" or "grind" the gears as can be done in a
more traditional style gearbox.
How to Drive a Ford Model T in Plain
English (Summary)
Ford made the Model T easy to drive compared
to today's cars since the people he sold his cars to did not
know how to drive anything other than a horse. It is not like
driving a modern car, even though there are three pedals on the
floor like a modern manual transmission car. A Model T has a
steering wheel that works the same way as in cars of today, but
almost everything else is different.
The first Model T's did not even have a starter like a modern
car. This is the powerful electric motor in a car that turns the
engine to make it run when it is turned off. The engine on the
Model T was started with a hand crank on the front of the car. A
wire loop near the radiator worked the choke on the carburetor
to give the engine extra fuel to help start it when it was cold.
This could be dangerous if a person was not careful. If the
levers that controlled the engine were not set the right way,
especially the spark control, the engine could backfire, or spin
the wrong way. Many people got broken arms this way.
Doctors even had a special name for this kind
of break: the "Ford Fracture." Many Model T owners added
electric starters to their cars and it was not long before Ford
started doing the same. A Model T is in high gear by default, so
if the Parking/Clutch lever was not engaged, the car had a
tendency to run over the operator when started.
To make a modern car go or accelerate once the engine is
running, a person steps on a pedal on the floor to engage the
transmission into low gear. To make a Model T accelerate, move
two levers near the steering wheel. The lever on the right was
the throttle (or engine speed), and the lever on the left
adjusted the time that the spark plugs fired. These levers
needed to be set properly before the engine could be started.
The three pedals on the floor of the Model T were for the brake
on the right, reverse in the middle to make the Model T go
backwards, and a pedal on the left to shift the gears from low
to high speed. A lever on the floor worked the brakes as well as
the clutch. Pulling the lever toward the driver would set the
parking brake and help keep the car from moving while parked.
When the lever was placed in the middle, the transmission would
be in neutral.
Once the engine is running, the driver now has to make the Model
T move on its own. Step on the pedal all the way to the left,
move the throttle lever to "give it the gas" and gently move the
floor lever forward. This is low gear, the powerful gear used to
get the Model T moving. Once it's moving, move the right lever
up, let the left pedal come all the way up, and give it more gas
to shift into high. To make the car go faster still, move the
throttle lever as well as the spark advance lever. Stepping on
the left pedal only halfway puts the car in neutral, the same as
the lever. This helps the Model T come to a stop without causing
the engine to stop as well.
The brakes on a Model T work the rear wheels by the use of brake
bands inside the transmission. Modern cars have brakes on all
four wheels. No brakes are on the front of a Model T.
More than fifteen million (15,000,000) Model T cars were built.
It was not until 1971 that the record was broken by the
Volkswagen. Today, the record for the most cars built is held by
the Toyota Corolla.
The Model T was nicknamed the "Tin Lizzie" and "Flivver" by the
people who drove it. A new car took the place of the Model T in
1928, the Ford Model A. |
