International Harvester Series 100/200, 130, 140, 200, 230, 240, 404, 2404 Tractor Repair Manual 1958–1974; 1940–1983 (P/N UT2222S)

This official 56-page OEM PDF publication (P/N UT2222S) is the definitive shop reference for the 1940–1983 International Harvester tractor lineup. Designed for professional technicians and serious DIY mechanics, it details the complete architecture of the Series 100 through 2404. Getting accurate specs quickly means less downtime in the bay. Having direct access to factory-specified dimensional data and clearances minimizes diagnostic time, allowing you to accurately identify hydraulic pressure drops and set gear backlash without resorting to costly component guessing or part-swapping. Before diving into major teardowns, remember that working on heavy agricultural equipment requires proper shop safety protocols, including load-rated jack stands and relieving hydraulic pressure prior to line removal.

• Covers 1940–1983 IH models, including the 100, 130, 140, 200, 230, 240, 404, and 2404 (Standard, Hi-Clearance, and Farmall variants).
• Contains 47 exploded-view diagrams, wiring diagrams, sectional views, cut-away views, schematic illustrations, and tune-up spec charts for rapid component diagnostics.
• Provides precise factory data for overhauling Tel-A-Depth systems, Hydra-Creeper transmissions, Dual Range units, Forward and Reverse drives, Power Take-Off (PTO) assemblies, Rockford clutches, and Auburn clutches.
• Outlines component teardowns for Ensign LP-Gas setups, Marvel-Schebler carburetors, Carter carburetors, Zenith carburetors, Delco-Remy distributors, H-4 magnetos, and power steering rotary valves.

Mechanical System Specifications

The manual delivers structured data essential for full-system overhauls. It outlines the documentation for engine removal, cylinder head torquing sequences, valve train specs, and timing gear configurations for the C-123 and C-135 powerplants. For chassis work, you will find steering gear teardown specs for both adjustable and non-adjustable front axles. The drivetrain section lays out clearances for major transmission overhauls, covering countershafts, spline shafts, and dual-range units to help you nail the correct backlash and shim selection. Brake service parameters are also detailed for both external band and self-energizing disc setups. By detailing step-by-step repair instructions for splitting the tractor to overhaul the clutch and synchronizing the complex Tel-A-Depth draft control linkage, the text enables you to handle intricate jobs that usually require an expensive trip to a specialized dealership.

Hydraulic and Electrical Data

Troubleshooting fluid power issues is straightforward with the included breakdown of Touch-Control and Hydra-Touch systems. The text documents circuit pressure testing, pump rebuild specs, and valve block diagnostics. On the electrical side, it covers timing parameters for battery ignition and magneto systems. You get specific advance curves and breaker point gaps mapped to their corresponding distributor symbols. Key metrics like the 0.014-inch intake valve clearance and the 3.5-gallon coolant capacity are listed in quick-reference tables. It also includes exact magneto pick-up resistance values for the 100/200 series, ensuring your ignition rebuilds meet factory standards.
