1979 Ford 1100, 1300, 1500, 1700 & 1900 Tractor Repair Manual Supplement

• Covers 1979 Ford 1100, 1300, 1500, 1700, and 1900 tractors equipped with liquid-cooled, overhead valve diesel engines
• Official Ford Tractor Operations publication SE 3771-S2, released directly as a supplement to the 1000 Series repair guide
• Documents critical specifications including engine displacement, cylinder compression, and rated engine speeds
• Features 71 highly detailed exploded-view diagrams detailing hydraulic pumps, front PTO assemblies, and internal engine components
• Fully searchable text layer allows technicians to instantly pinpoint specific torque values or clearance data during bench work
• Spanning 685 pages, the manual acts as the definitive reference for resolving the specialized hydraulic and PTO configurations absent from the base 1000 Series literature

Hydraulic and PTO System Walkthrough

Navigating the specialized fluid systems across the Ford 1100–1900 line requires exact documentation. This manual breaks down the internal flow paths for both single and double-acting cylinders. It clearly maps the operational sequences across lifting, lowering, and neutral positions. Technicians working on high-pressure hydraulics must always verify system depressurization before cracking lines; this text provides the precise diagnostic routing needed to trace hydraulic pump performance safely without guesswork. Subsequent sections dissect the draft control linkage. This covers both the dual linkage and position control mechanisms essential for accurate field operations.

Specification Highlights

Factory tolerances dictate the success of any heavy diesel overhaul. The text catalogs precise engine identification codes and dimensional limits for every model variant in the series. It specifies a strict cylinder head warpage limit of 0.005 in. (0.12mm) prior to resurfacing. You will find exact intake valve stem diameters mapped to a 0.310 in. (7.88mm) minimum. The documentation also details critical fluid thresholds. Relief valve pressure settings are distinctly separated: 1849 psi (130 kg/cm2) for the 1100, while 1300–1900 models run at 2133 psi (150 kg/cm2). Connecting rod bolt torque specifications are explicitly listed down to the 3.5–4 ft-lbs (25–28 Nm) range for the 1300. Overall, the literature lays out the exact mechanical benchmarks necessary for comprehensive component inspection and adjustment.
