International Harvester was formed in Chicago in 1902 and became a major American builder of farm tractors, trucks, and construction equipment. This page offers repair and service manuals for International Harvester engines, covering the gasoline and diesel powerplants used across its tractor and truck lines.
International Harvester, known as IH, was formed in 1902 in Chicago through the merger of the McCormick Harvesting Machine Company and the Deering Harvester Company. What began as an agricultural equipment maker grew into a diversified manufacturer building farm tractors, trucks, and construction machinery under one roof, becoming a familiar name across American farms and highways alike.
On the agricultural side, IH is remembered for its Farmall tractors, introduced in 1924, while its truck lineup included the Auto Buggy dating back to 1907, along with later models such as the Loadstar and Fleetstar. The company also built the Scout utility vehicle from 1961 to 1980 and a range of construction equipment, giving it a presence across farm fields, highways, and job sites alike.
IH engines covered in these manuals include the C-series and BD-series gasoline sixes, the D-series diesels, and the DT466 diesel introduced in the 1970s. Each manual includes engine rebuild procedures, transmission service, electrical systems and wiring diagrams, torque specifications, diagnostic guidance, and scheduled maintenance information for these tractor, truck, and construction equipment engines.
In 1985 IH sold its agricultural line, which became Case IH, and the company itself was renamed Navistar in 1986. Owners restoring IH tractors and trucks, independent repair shops, and workshops servicing older construction equipment all rely on these manuals for accurate, factory-level repair information and procedures.
