Ford Manual
The following is reproduced from the 1926 FORD MANUAL which was supplied with a new Model
T Ford. Manuals similar to this one came with every Ford during many years and gave somewhat
detailed instructions to the owner on how to operate and make repairs on his car.
Many common questions regarding the operation and maintenance of the Model T Ford can be
found here.
What must be done before starting the Car?
Before starting the car, fill the radiator (by removing cap at top) with clean fresh water. If perfectly clean
water cannot be obtained it is advisable to strain it through muslin or other similar material to prevent
foreign matter from getting in and obstructing the small tubes of the radiator. The system will hold
approximately three gallons. It is important that the car should not be run under its own power unless the
water circulating system has been filled. Pour in the water until you are sure that both radiator and
cylinder water jackets are full. The water will run out of the overflow pipe onto the ground when the
entire water system has been properly filled. During the first few days that a new car is being driven it is
a good plan to examine the radiator frequently and see that it is kept properly filled. The water supply
should be replenished as often as may be found necessary. Soft rain water, when it is to be had in a clean
state, is superior to hard water, which may contain alkalis and other salts which tend to deposit sediment
and clog the radiator. (See chapter on Cooling System.)
What about Gasoline?
The ten-gallon gasoline tank should be filled---nearly full---and the supply should never be allowed to
get low. When filling the tank be sure that there are no naked flames within several feet, as the vapor is
extremely volatile and travels rapidly. Always be careful about lighting matches near where gasoline has
been spilled, as the air within a radius of several feet is permeated with the highly explosive vapor. The
small vent hole in the gasoline tank cap should not be allowed to get plugged up, as this would prevent
proper flow of the gasoline to the carburetor. The gasoline tank may be drained by opening the pet cock
in the sediment bulb.
How about the Oiling System?
Upon. receipt of the car see that a supply of medium light, high-grade gas engine oil is poured into the
crank case through the breather pipe at the front of the engine (a metal cap covers it). Down under the
car in the flywheel casing (the reservoir which holds this oil) you will find two pet cocks. Pour oil in
slowly until it runs out of the upper cock. Leave the cock open until it stops running---then close it. After
the engine has become thoroughly limbered up, the best results will be obtained by carrying the oil at a
level midway between the two cocks-but under no circumstances should it be allowed to get below the
lower cock. All other parts of the car are properly oiled when it leaves the factory. However, it will be
well to see that all grease cups are filled and that oil is supplied to necessary parts. (See Cut No. 16, also
chapter on Lubrication.)

Summary of Contents for Ford Model T 1926

  • Page 1 The following is reproduced from the 1926 FORD MANUAL which was supplied with a new Model T Ford. Manuals similar to this one came with every Ford during many years and gave somewhat detailed instructions to the owner on how to operate and make repairs on his car.
  • Page 2 Ford Manual Under the steering wheel are two small levers. The right-hand (throttle) lever controls the amount of mixture (gasoline and air) which goes into the engine. When the engine is in operation, the farther this lever is moved downward toward the driver (referred to as "opening the throttle") the faster the engine runs and the greater the power furnished, the left-hand lever controls the spark, which explodes the gas in the cylinders of the engine.
  • Page 3 Ford Manual If the car is not equipped with a starter the engine is started by the lifting of the starting crank at the front of the car. Take hold of the handle and push firmly toward the car till you feel the crank ratchet engage, then lift upward with a quick swing.
  • Page 4 Ford Manual Its chief purpose is to hold the clutch in neutral position. If it were not for this lever the driver would have to stop the engine whenever he left the driver's seat. He would also be unable to crank the engine without the car starting forward with the first explosion.
  • Page 5 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.
  • Page 6 The time gears must mesh so that the tooth marked "Ford" on the small time gear will come between the two teeth on the large gear at the point marked zero (0). The time gears now being properly set, the exhaust valve on No.
  • Page 7 Put the valve in position on the valve seat, and rotate it back and forth (about a quarter turn) a few times, with a Ford grinding tool. Then lift slightly from the seat, change the position and continue the rotation, and keep on repeating this operation until the bearing surface is smooth and bright.
  • Page 8 Ford Manual When the Valves and Push Rods are worn---what? Answer. No. 26 When the valves or push rods become worn, so as to leave too much play between them, thus reducing the lift of the valves and diminishing the power of the motor, it is best to install new push rods. If replacing the push rod does not give the desired clearance, the valve should also be replaced.
  • Page 9 (keeping it well supplied with water and oil) before taking it out on the road. Whenever possible these bearings should be fitted by an expert Ford mechanic. Worn connecting rods may be returned, prepaid, to the nearest dealer for exchange at a price of $0.60 each to cover the cost of rebabbitting.
  • Page 10 The Ford Cooling System How is the Engine cooled?
  • Page 11 The heat generated by the constant explosions in the engine would soon overheat and ruin the engine, were it not cooled by some artificial means. The Ford engine is cooled by the circulation of water in jackets around the cylinders. The heat is extracted from the water by its passing through the thin metal tubing of the radiator---to which are attached scientifically worked out fins, which assist in the rapid radiation of the heat.
  • Page 12 If the entire radiator is badly jammed or broken it would probably be advisable to install a new one. The Ford Gasoline System The Carburetor---how does it work? Answer No. 42 The carburetor is of the automatic float feed type, having but one adjustment---the gasoline needle valve.
  • Page 13 Ford Manual For the convenience of the driver in adjusting the carburetor. After the new car has become thoroughly worked in, the driver should observe the angle of the carburetor adjusting rod at which the engine runs most satisfactorily. In cold weather it will probably be found necessary to turn the adjusting rod one- quarter turn to the left, particularly in starting a cold engine.
  • Page 14 It is important that the charge be correctly ignited at the proper time, in order to obtain satisfactory results in running the car. In the Ford car the ignition system is as simple as it is possible to make it.
  • Page 15 Ford Manual With the vibrators properly adjusted, if any particular cylinder fails or seems to develop only a weak action, change the position of the unit to determine if the fault is actually in the unit. The first symptom of a defective unit is the buzzing of the vibrator with no spark at the plug. Remember that a loose wire connection, faulty spark plug, or worn commutator may cause irregularity in the running of the motor.
  • Page 16 There is nothing to be gained by experimenting with different makes of plugs. The make of plugs with which Ford engines are equipped when they leave the factory are best adapted to the requirements of our motor, notwithstanding the opinion of various garage men to the contrary. All wire connections to spark plugs, coil box and commutator should, of course, at all times be kept in perfect contact.
  • Page 17 The new magnets may be obtained from the nearest Ford Dealer, placed on a board in identically the same manner as they should be when installed on the flywheel. Great care should be taken in assembling the magnets and lining up the magneto so that the faces of the magnets are separated from the surface of the coil spool just 1/32 of an inch.
  • Page 18 Ford Manual It is that part of the mechanism of an automobile which lies between the crank shaft and the drive shaft and by which one is enabled to move at different speeds from the other. It is the speed gear of the car. It permits driving the car forward at low and high speeds and by it the car is reversed.
  • Page 19 The bands, when worn to such an extent that they will not take hold properly, should be relined, so that they will engage smoothly without causing a jerky movement of the car. The lining is inexpensive and may be had at any Ford service station at small cost.
  • Page 20 Ford Manual The lock washers and nuts may then be replaced and the bands adjusted in the regular way. How is the Transmission assembled? Answer No. 76 Cut No. 12 shows the transmission parts in their relative assembling positions and grouped in their different operations of assembling.
  • Page 21 Ford Manual inside so that the flange will rest on the upper coil of the spring and press into place, inserting the pin in the driving plate hub through the holes in the side of the spring support. Then turn the clutch spring support until the pin fits into the lugs on the bottom of the support.
  • Page 22 The Ford Muffler Why is the Muffler necessary? Answer No. 83...
  • Page 23 The Ford muffler construction is such that there is very little back pressure of the escaping gases, consequently there is nothing to be gained by putting a cut-out in the exhaust pipe between the engine and the muffler.
  • Page 24 After disconnecting the spring, the brake shoe can be lifted off of the axle brake housing plate. New linings and rivets may be obtained from any Ford Dealer, and you can readily see how the lining is attached to the brake shoe.
  • Page 25 Ford Manual The front wheels are placed at an angle---that is to say, the distance between the tops of the front wheels is about three inches greater than between the bottoms. This is to give perfect steering qualities and to save wear on the tires when turning corners.
  • Page 26 It is also advisable to inspect the front spring and front spring perches occasionally to determine whether or not new bushings are necessary to overcome any excessive vibration. The Ford Lubricating System...
  • Page 27 It is simplified---and there are fewer places to oil. Practically all of the parts of the engine and transmission are oiled by the Ford splash system, from the one big oil reservoir in the crank case. Cut No. 16 shows the principal points of lubrication, and specifies when replenishment should be made, according to mileage.
  • Page 28 The oil plug should be removed about every 1000 miles and more grease added if necessary. If a fluid grease is used the level should be approximately one and one-half inches below the oil hole. How are Ford Tires removed? Answer No. 105...
  • Page 29 Should the casing be cut so there. is danger of the inner tube being blown through it, a temporary repair can be made by cementing a patch, such as sold by Ford Dealers, on the inside of the casing. Before applying the patch, the part of the casing affected should be cleaned with gasoline and when dry, rubber cement applied to the casing only.
  • Page 30 When putting the top down be careful in folding to see that the fabric is not pinched between the bow spacers, as they will chafe a hole through the top very quickly. Applying Ford top dressing will greatly improve the appearance of an old top.
  • Page 31 Ford Manual Do the Instructions relative to the Car apply to the Truck? Answer No. 112 The answers pertaining to the car are applicable to the truck, with the exception of Nos. 79, 80 and 82. How are the Rear Axle and Differential disassembled? Answer No.
  • Page 32 The Ford Starting and Lighting System Of what does the Starting and Lighting System consist? Answer No. 117 The starting and lighting system is of the two unit type and consists of the starting motor, generator, storage battery, ammeter, and lights, together with the necessary wiring and connections.
  • Page 33 Answer No. 123 The starting motor is lubricated by the Ford splash system, the same as the engine and transmission. The generator is lubricated by a splash of oil from the time gears. In addition an oil cup is located at the end of the generator housing and a few drops of oil should be applied occasionally.
  • Page 34 Ford Manual The ammeter is located on the instrument board. This indicator registers "charge" when the generator is charging the battery and "discharge" when the lights are burning and the engine not running above 10 miles per hour. At an engine speed of 15 miles per hour or more the ammeter should show a reading of from 8 to 10 with lights turned off.
  • Page 35 Ford 21 candle-power gas filled bulbs be used in the lamps equipped with the Ford Refracting Lens as the use of any other than genuine Ford bulbs may result in the lights failing to .meet the lighting requirements of the various states. Care should be exercised not to touch the reflector except with a soft clean cloth.
  • Page 36 28 inches apart. (See plate No. 23.) Owners may prefer to have their lamps focused and aligned by an authorized Ford dealer as all Ford dealers are specially equipped to do this work.
  • Page 37 Never ground the generator through the cut-out. What type of Battery is used? Answer No. 138>/b> The Ford Starting System uses a six-volt, three-cell Ford battery. How are Hydrometer Readings taken? Answer No. 139...
  • Page 38: Engine Fails To Start

    Water and electrolyte, and avoid freezing. If, for any reason, it is necessary to add acid, the battery should be taken to an authorized Ford Dealer. What care should be given the Filling Plugs and Connections? Answer No.
  • Page 39: Engine Overheats

    Ford Manual 6. Gasoline supply shut off. 6. Magneto contact point obstructed. 7. Carburetor frozen (in zero weather). 7. Overheated---account lack of oil or water. 8. Water frozen in gasoline tank sediment bulb. 8. Gas mixture too lean. 9. Ignition switch off.
