International Harvester – other models: trucks outside the named series, including the Loadstar, up to 242.4 kW (325 hp), six- to eight-cylinder engines, 5,310 to 7,210 kg kerb weight

This page gathers International Harvester trucks that the register could not assign to a named series, including the Loadstar, IH's medium-duty range of the 1960s and 1970s. International Harvester was headquartered in Chicago and was renamed Navistar in 1986; the engines came from the manufacturer's own engine programme and used overhead-valve design.

The register lists 6 versions with up to 242.4 kW (325 hp), displacements of 5,700 to 10,400 cc from six- to eight-cylinder engines, kerb weights of 5,310 to 7,210 kg and gross vehicle weights of 7,490 to 11,412 kg, lengths of 7,000 to 10,200 mm and widths of 2,400 to 2,450 mm.

For much of the 20th century, International Harvester was one of the most significant American commercial vehicle makers alongside Ford, Chevrolet and Dodge; the Loadstar, as a robust medium-duty truck, saw wide use with municipalities, fire departments and in commercial distribution, while the brand also played a major role in farm equipment.

When buying used, check for rust on the frame and cab, the condition of the valve train on the older overhead-valve engines, and the brake system, plus tightness of fuel lines and gaskets on the old six- and eight-cylinder engines; parts availability is limited and runs mostly through specialist vintage dealers for American commercial vehicles in North America.

What to check before buying

Check the hour meter against the service records — a replaced instrument is the most common gap.

Check the weights in the papers against the figures here — attachments change them.
Shift the gearbox cold and warm — jumps only show up at temperature.
Ask about parts availability for this build year — the running costs hang on it.
