Ford Manual
The different speeds required to meet road conditions are obtained by opening or closing the throttle.
Practically all the running speeds needed for ordinary travel are obtained on high gear, and it is seldom
necessary to use the low gear except to give the car momentum in starting. The speed of the car may be
temporarily slackened in driving through crowded traffic, turning corners, etc., by "slipping the clutch," i.
e., pressing the clutch pedal forward into neutral. When doing this the throttle lever should be nearly
closed.
Is it advisable for owners to make their own Adjustments?
Answer No. 16
The Ford is the simplest of all cars. Most of the ordinary adjustments an owner will soon learn to make
for himself. But we must strongly recommend that when it becomes necessary to employ the services of
a mechanic, the car be taken to a Ford mechanic---one of our own representatives who thoroughly
understands the car---and who will have no motive for running up useless repair bills. The entire Ford
organization is interested in keeping every individual Ford car in constant operation, at the lowest
possible cost. We have known of much damage done to many cars by unskilled repair men.
What attention does the Car need?
Answer No. 17
Remember that a new machine requires more careful attention during the first few days it is being driven
than after the parts have become thoroughly "worked in." The car which is driven slowly and carefully
when new usually gives the most satisfactory service in the end. Never start out with your car until you
are sure that it has plenty of oil, water and fuel. Frequently inspect the running gear. See that no
unnecessary play exists in either front or rear wheels, and that all bolts and nuts are tight. Make a
practice of taking care of every repair or adjustment as soon as its necessity is discovered. This attention
requires but little time and may avoid delay or possible accident on the road. We aim to deliver the car in
proper mechanical adjustment. Afterwards it is plainly the duty of the driver to keep it in that condition.
The Ford Engine
What is the principle of the gasoline-driven Engine?
Answer No. 18
Gasoline when mixed with air and compressed is highly explosive. An explosion is a violent expansion
caused by instantaneous combustion of confined gases. In the gasoline engine the mixture is drawn into a
cylinder, where it is compressed by an advancing piston and then exploded by an electric spark, which
sends the piston downward, and through the connecting rod imparts a rotary motion to the crankshaft.
What are functions of the Pistons?
Answer No. 19
On the downward stroke the suction of the piston draws the fresh gas from the carburetor, through the
inlet pipe and valve, into the cylinder. The upward movement of the piston compresses the gas into a
very small space, between the top of the piston and the depression in the cylinder head, known as the
"combustion chamber." (The compressed gases exert a pressure of approximately 60 pounds per square
inch.) At this point the electric spark explodes the gases---driving the piston downward---thus producing
the power which turns the crankshaft. On the next stroke upward the piston drives the exploded gas out
through the exhaust valve and pipe to the muffler. (See Cut No. 2.)
Connecting Rod---how removed?
Answer No. 20
It is a steel rod, connecting piston and crank shaft. Should the babbitt bearing become worn, or burned
out through lack of oil, a knocking in the engine will result---in which case the entire connecting rod
should be replaced. To make this replacement, (1) drain oil from crank case; (2) take off cylinder head;
(3) remove detachable plate on bottom of crank case; (4) disconnect connecting rod from crank shaft; (S)
take piston and rod out through top of cylinder.
When replacing a rod on which babbitt has burned out, make sure the crankshaft is free from any babbitt
left by the burned out rod. This babbitt can be removed by means of a piece of oiled sandpaper.
