BREAK IN PERIOD - free allis chalmers tractor manuals. The tractor engine is assembled and tested and ready for work, however for best results operate tractor under medium loads for the first 10 to 20 hours of operation.. If possible it should be operated at full governed r.p.m. of engine. If necessary use a lower gear to keep from overloading engine. In cold weather the oil should be changed after the first 20 to 30 hours of operation. However if the proper temperature is maintained at all times the lubricating interval outlined in lubrication guide may be followed.

STARTING ENGINE allis chalmers d14 service manual pdf
1. Before starting tractor make certain that all points of care and lubrication outlined under daily, weekly or 30 day check have been serviced as specified.
2. Close radiator shutter by turning screw crank located on right hand side of tractor.
3. If gasoline is to be used open valve under large tank. If low octane fuel is used open valve under small tank. Move throttle control 
lever down about one fourth of quadrant. Place gear shift in neutral position. In cold 
weather hold clutch pedal down until engine starts to relieve starter load.
4. Pull out magneto switch on instrument panel.
5. Pull carburetor choke rod located at right side of steering column.
6. Pull out on starter pull rod located on left side of steering column. Engage starter firmly to insure good switch contact. Release immediately when engine starts, When engine has turned one complete turn, push choke rod forward, If weather is extremely cold more choking may be necessary.

STARTER - The starter very seldom causes difficulty, however, if it fails to turn the engine properly with a fully charged battery, check all connections making sure they are clean and tight.
If difficulty is experienced with the starting motor, any one of the following may be the c a u s e :
1. Exhausted battery.
2. Broken or loose wires.
3. Loose or corroded battery terminals.
4. Starter switch making poor contact.
GENERATOR - The generator charging rate is controlled by a resistance unit built into the light switch. This resistance unit limits the amount of current allowed to flow through the field coils of the generator.
The tractor is shipped with the field wire on the generator disconnected. This wire must be connected in order to complete the circuit. If the battery is removed and the engine must be operated without the battery in place, disconnect the field wire to prevent damage to the generator.
The generator very seldom causes any difficulty, however, if it does it is usually caused by a dirty or oily commutator. To clean 
remove the band over the brushes. Use grade “00” sandpaper, With engine running hold the sandpaper against the commutator. Do not use emery cloth as emery will cause short circuiting,
CUTOUT RELAY - The cutout relay is mounted on the top of the generator and provides an ‘automatic switch for closing the generator circuit. If the points in the cutout fail to close, the ammeter will remain at zero. Do
, not operate the tractor in this condition as damage to the generator will result.

BATTERY - The starting and lighting system uses a six volt battery, designed and built to meet the requirements of the tractor.
Check the electrolyte (solution) in the battery at least once each week to see that it is at the proper level. This level should be maintained to lower edge of filler tube (which is about l/4” above top of separators). The battery supplied with your tractor has a lead washer type valve in the filler tube to prevent over filling. Never add anything to the solution except DISTILLED or RAIN water. Boiled water will not do. The supply of water should be kept in clean, covered vessels of glass, china, rubber or lead.
Do not allow lighted matches or an open flame of any kind near battery cell covers. The need for frequent addition of water to battery, indicates the charging rate maintained is too high.
In cold weather, add water only immediately before running the engine so that the charging will mix the electrolyte and water and prevent freezing. A fully charged battery will not freeze in very cold temperatures, but if only partly charged, will freeze and be ruined at much higher temperatures. Weekly readings of each battery cell should be taken with a battery hydrometer. The readings indicate 
. as follows: 1.280, full charge; 1.225, half charge; 1.150 discharged.
By taking frequent readings with the hydrometer, it is possible to keep generator charging 
rate so adjusted as to have battery fully charged, but not over charged. When taking the readings, return the electrolyte to the cell from which it was taken.
Due to the infrequent use of tractor in cold weather and the extra amount of electrical energy required by starting motor, it is usually necessary to use a higher charging 
rate than in summer, to keep battery fully charged. Refer to instructions on ammeter 
for charging information.

Keep the battery clean by using a stiff bristle brush -- not metal. If terminals are corroded or if the battery is acid soaked, wash with soda solution (l/4 lb. of soda to one quart of water). Vent plug must be kept in place when cleaning battery. After washing battery check gas escape holes in vent caps making sure they are open. If the battery is removed from tractor, disconnect the grounded positive terminal first. When re-installing be sure the ground cable is installed last and connected to the positive post. Battery box cover should be in place and tightened snugly to prevent battery from being damaged by vibration. (Be sure that wood spacer is between top of battery and cover.)
In event the tractor is not to be used for some time, it is advisable to remove the battery, have it fully charged and stored in a dry basement or some similar place where the temperature is to be as low as possible, but above freezing.

Place tube in tire and apply a good grade of vegetable oil soap to base of tube and inside of tire. Place on rim and adjust tube and tire evenly all around. Inflate to seat tire on rim 
then deflate. Tire may then be filled with calcium chloride in usual manner or inflated to recommended pressure.
REAR WHEEL TREAD ADJUSTMENT - The power of the tractor may be applied to the wheel to increase or decrease tread width.
Remove the clamps from the guide. Turn the four eccentrics counter-clockwise as far as possible. Place the tractor in reverse or low, depending on whether spacing is to be made wider or narrower. Hold brake on opposite wheel and engage clutch. It sometimes helps to engage clutch suddenly to start movement in the wheel. If intermediate positions are needed install the clamp in the desired hole in guide rail and use it as a stop for locating position of the rim. InstalI second clamp on opposite side. Tighten the eccentric in a clockwise direction. Turn eccentric over against its stop. If the remaining eccentrics cannot be turned fully against the stop, return to stop‘ in counter-clockwise direction. The eccentric must be turned against stop to be self locking. Additional spacing of 70”to 90”may be secured by turning the dished wheel out”. To make this change raise tractor from ground and block securely. Place the wheel on opposite side of tractor. This will keep direction of tire tread correct.
