It covers every single detail.\u003c\/p\u003e\n\u003cp\u003eInternational Harvester Farmall A AV B BN Tractor Service Repair Workshop Manual PDF\nVEHICLE\/EQUIPMENT INTRODUCTION:\nThe International Harvester Farmall A, AV, B, and BN tractors, produced between 1939 and 1948, are iconic row-crop tractors that defined an era of American agriculture. The Farmall A was introduced in 1939 as a smaller alternative to the Farmall H, powered by the International C-113 engine producing approximately 15-16 drawbar horsepower on regular fuel. The AV variant runs on vaporized gasoline (propane\/kerosene), while the B is essentially the same tractor with a different hood and grille design, and the BN is the narrow-row version.\nThese tractors feature a distinctive tricycle front wheel configuration with adjustable rear tread width, making them ideal for cultivating row crops such as corn and cotton. With over 128,000 Farmall A and AV units produced at the Tractor Works in Chicago, these machines are among the most collectible vintage tractors today. Their simple 4-speed sliding gear transmission, magneto ignition system, and robust C-113 engine make them relatively easy to maintain, though original parts knowledge is invaluable.\nSERVICE \u0026amp; REPAIR SCOPE:\n- Engine C-113: cylinder head decarbonizing, valve grinding, piston ring replacement\n- Magneto ignition: magneto disassembly, points and condenser service, timing adjustment\n- Carburetor: Zenith or updraft carburetor rebuild, fuel mixture adjustment\n- Ignition system: spark plug wire routing, distributor cap inspection\n- 4-speed sliding gear transmission: gear tooth inspection, bearing replacement\n- Cooling system: thermosiphon cooling maintenance, water pump (if equipped) service\n- Braking system: single brake adjustment, brake band replacement\n- Hydraulics: Farmall touch-control hydraulic system service (if equipped)\n- Front axle: tricycle wheel fork inspection, kingpin bushing replacement\n- Rear axle: differential gear setup, final drive inspection\nTECHNICAL SPECIFICATIONS:\n- Engine: International C-113, 113 cu in (1.85L), 4-cylinder, naturally aspirated\n- Fuel type: Gasoline\/distillate (A\/B), vaporized fuel (AV\/BN)\n- Power: approximately 15-16 drawbar HP, 20 belt HP\n- Engine speed: 1400 RPM governed\n- Bore x Stroke: 3.0 x 4.0 inches\n- Transmission: 4-speed sliding gear, 1 reverse\n- Drive: 2-WD only\n- Front tire: 4.00-15 4-ply, Rear tire: 9-24 4-ply\n- Weight: approximately 1780 lb (808 kg)\n- Wheelbase: 71 inches\nDIAGNOSTIC INFORMATION:\n- Magneto timing: alignment of timing marks, impulse coupler function check\n- Compression testing: acceptable ring seal condition for vintage engine\n- Carburetor float level: fuel level at nozzle orifice, needle and seat inspection\n- Engine overheating: thermosiphon system flow check, radiator tube inspection for blockage\n- Transmission slipping: gear engagement depth check, shift fork wear assessment\n- Magneto failure: condenser breakdown testing, breaker point gap verification (typically 0.015 inch)\n- Oil pressure: visual drip-feed system \u003c\/p\u003e\n\u003cp\u003eInstant download — no shipping, no waiting.
