1979 Ford 1100, 1300, 1500, 1700 & 1900 Tractor Repair Manual Set (P/N SE 3771, SE 3771-S2 & SE 3771-S3)

This 1979 Ford tractor repair Manual Set combines base manual SE 3771 for the 1300, 1500, 1700, and 1900 with supplements SE 3771-S2 and SE 3771-S3. Coverage for the 1100 is limited to the supplemental hydraulic and front PTO material. The later supplement adds remote-valve and power-steering service for the 1700 and 1900.

• Engine and cooling: Engine removal, internal inspection, assembly, valve-lash adjustment, water-pump overhaul, and cooling-system pressure tests.

• Diesel fuel system: Injection-pump removal and timing, injector disassembly and inspection, fuel-system troubleshooting, and governor adjustment for the 1300.

• Electrical diagnosis: Glow-plug and safety-start circuit checks, starter-motor repair, alternator testing, regulator adjustment, and model-specific wiring diagrams.

• Clutch and transmission: Single-clutch service, the optional 1900 dual clutch, transmission overhaul, and inspection of gears, shafts, bearings, and shift mechanisms.

• Differential, axles, and brakes: Differential overhaul, rear-axle repair, brake inspection and adjustment, and separate two-wheel-drive and four-wheel-drive front-axle procedures.

• Hydraulics and steering: Hydraulic-pump and control-valve overhaul, draft-control linkage adjustment, remote-valve troubleshooting, and power-steering priority-valve service.

• Front PTO: Magnetic-clutch removal and disassembly, PTO-shaft service, and illustrations distinguishing the 1100 drive arrangement from the other covered models.

The internal overhaul procedures suit mechanics experienced with tractor disassembly and precision measurement, with access to lifting equipment, electrical test instruments, and clutch-alignment tools.

Engine Overhaul and Fuel-System Limits

The engine chapters cover precombustion chambers, valves, pistons, rings, connecting rods, cylinder bores, crankshafts, and camshafts. Inspection charts distinguish standard dimensions from wear limits; related sections address lubrication-system components, coolant-loss diagnosis, radiator-cap testing, and thermostat operation.

Injection timing is separated by engine configuration and by whether original drive components or replacement parts are being installed. The 1300 governor section includes assembled and exploded linkage views.

Injection-pump scope: The manual provides removal, installation, timing, and reference exploded views. It specifies replacement of a defective pump as an assembly rather than an internal pump overhaul procedure.

Clutch, Transmission, and Axle Configurations

The clutch material distinguishes the standard single clutch from the optional 1900 dual clutch, including pressure-plate inspection and release-lever adjustment. Transmission assembly instructions also identify the separate procedure for the dual-clutch 1900.

Differential sections address PTO gearing, optional creeper gearing, and front-wheel-drive components. Rear-axle chapters cover final-drive components and mechanically operated internal-expanding brakes. Front-axle service distinguishes adjustable and nonadjustable axles, with kingpin-seal replacement, toe-in adjustment, wheel-tread settings, and tractor-weighting information.

Remote Hydraulics, Draft Control, and Front PTO

Remote Valve Oil Flow diagrams show neutral, lifting, and lowering operation with single- and double-acting cylinders. Troubleshooting charts distinguish weak lifting, slow response, and implement drift, helping a mechanic separate pump-delivery problems from valve or cylinder leakage.

The Linkage System — Position and Draft Control illustration and Dual Linkage view explain how the feedback mechanisms act on the pilot spool. Hydraulic service requires pressure-release precautions before lines are opened.

Front PTO Drive illustrations distinguish the 1100 belt-and-sheave arrangement from the shaft-and-coupling drive used on the other models. Front PTO units supplied as part of an implement are outside these repair instructions.

The power-steering supplement covers the priority valve, steering cylinder, control valve, ball nut, sector shaft, and gearbox. Priority Valve — Oil Flow views explain flow division between steering and tractor hydraulics. Its disassembly notes warn that excessive force on the plunger core can damage the orifice.

Starting and Charging Circuit Diagnosis

Circuit checks cover glow plugs, the starter switch, safety start switch, starter solenoid, and charging system. Separate wiring diagrams for the four base-manual models show connector terminals and wire-color codes; alternator tests distinguish diode, stator, rotor, and regulator faults.

The glow-plug chapter includes a warning against opening the sealed plugs. Starter testing also identifies conditions that can cause unintended motor rotation or solenoid overheating.

Examples of Engine Inspection Limits and Hydraulic Pressures

These examples are a small selection of the inspection and operating specifications in the set.

For all four engines in the base manual, the cylinder-head tables list maximum warpage of 0.005 in. (0.12 mm). The intake-valve tables specify a minimum stem diameter of 0.310 in. (7.88 mm).

The remote-hydraulic-valve supplement describes relief opening at 1849 psi (130 kg/cm²) for the 1100 and 2133 psi (150 kg/cm²) for the 1300, 1500, 1700, and 1900.

PDF Search, Bookmarks, and Publication Breakdown

Finding procedures and reading diagrams: OCR text search is available throughout the technical sections. The opening supplementary cover and contents pages are not searchable. Embedded bookmarks link the publications and major chapters. Small wiring-diagram labels require zooming for comfortable reading.
