The 21 models of the full lineup had a high degree of parts interghangability this standardization helped lower the number of parts used by 30%. In the summer of 1978, lighter-GVWR models (replacing the Loadstar) were released for sale. The initial lineup consisted of heavier-duty 2200, 2500, and 2600 models (28,000-45,000 lb gross vehicle weight rating - GVWR), replacing the Fleetstar.

In April 1977, International Harvester unveiled the medium-duty S series at an event at the New Orleans Superdome. Navistar 2500 in use as a municipal service truck After 2001, International phased in product lines based upon the "NGV" architecture severe-service and bus chassis variants produced through 20, respectively. During 1989, the S-Series underwent a major revision and was split into multiple model lines. The last complete product line designed within the existence of International Harvester, the S series was produced in its original form through 1989.

The chassis was produced with both gasoline and diesel powertrains (the latter exclusively after 1986), single or tandem rear axles, and two, four, or, six-wheel drive layouts. Additionally, the S series was produced in other body configurations, including a four-door crew cab, cutaway cab, cowled chassis, and a stripped chassis (primarily for school buses). The IHC S series was produced in a number of variants for a wide variety of applications, including straight trucks, semitractors, vocational trucks, and severe-service trucks. Introduced to consolidate the medium-duty IHC Loadstar and heavy-duty IHC Fleetstar into a single product range, the S series was slotted below the Transtar and Paystar Class 8 conventionals. The International S series is a range of trucks that was manufactured by International Harvester (later Navistar International) from 1977 to 2001.

International 4000 series/DuraStar (2001).Hit the play button below to see the old cab-over-engine dump truck come back to life and learn a few things about repairing the tried-and-true IH V345. Granted, it's not yet ready to hit the road again, but it will return to hauling after a few more repairs. Parked for decades alongside a bigger Loadstar, the 1964 CO 1600 fired up its V8 engine for the first time in many years with not so much work. And the cab-over 1600 dump truck in the video below is the perfect proof. These engines are so well built that not only they can take a lot of abuse, but they also refuse to die after sitting for decades. They were notoriously thirsty, especially under heavy load, but they're often described as "bulletproof" and capable of running well beyond 150,000 miles (241,400 km) without notable repairs. Shared with International's pickups and wagons, the 345 wasn't impressively powerful at 197 horsepower, but it was a torque powerhouse at 309 pound-feet (419 Nm). In 1974 the V345 became standard on the 1600 as well. Part of the company's V304/345/392 series of gasoline mills, the 345 was originally optional on the 16 and standard on the 1800. These trucks are among the most reliable ever built by International Harvester, especially those fitted with the brand's 345-cubic-inch (5.7-liter) V8 engine. Produced until 1971, when it was replaced by the Cargostar, it came with loaded weights ranging from 19,500 to 27,500 pounds (8,845 to 12,474 kg). It was sold as the Loadstar CO and came in 1600, 1700, and 1800 trims. From the entry-level Binder to the range-topping F1850 6x4, the Loadstar returned gross vehicle weight ratings from 19,200 to a whopping 46,000 pounds (8,709 to 20,865 kg).Īnd much like any other truck company at the time, International developed a forward control, cab-over-engine version of the hauler. And International Harvester built no fewer than seven different variations of the truck. Developed as a medium-duty truck, the Loadstar was initially slotted between the C-Line pickups and the heavy-duty R-series.
