The last complete product line designed within the existence of International Harvester, the S series was produced in its original form through 1989. Introduced in 1979, the bus variant of the S series would be one of the final models designed by International Harvester before its transition to Navistar. To be able to perform at this level, the vehicles need a strongest chassis, capable suspensions and powerful and reliable engines. Production of the light duty S series ended in 1957, when it was replaced by the. Its power comes from the MaxxForce range of engines which feature CleanBurn Emissions Technology and will also be available with optional natural gas version from early 2013. In contrast, the interior would see several updates.
The International Workstar is part of this family and it was designed as a versatile line of severe work trucks, from medium duty to heavy duty applications class 7 and 8. We can shorten wheel base for you! The S series would be produced throughout the 1980s largely unmodified. The Vista combined design elements of a conventional and a forward control school bus. Although the cab itself was retained, interiors saw complete redesigns, with all-new dashboards and interior controls; a two-spoke steering wheel replaced the previous three-spoke design in use. These wore vertical grille slats instead of horizontal ones seen since 1989 although the horizontal grille slats continued to be produced for the 3800 until 2004. Designed as a replacement for the bus chassis, the S-series bus chassis was produced in two distinct generations.
It was produced from 1991 until 1998 when Thomas chose to discontinue Vista production after the body manufacturer's purchase by. The truck has a 6x4 or 4x2 axle configuration and is available with a choice of either Day or Sleeper cabs. After 1994, the 3700 was discontinued. The truck was designed for long haul operations and features an aerodynamic design that reminds us of those classic hot roads that caused many jaw drops at their time. In addition, the S series formed the basis for its own generation of the wagon, marking the introduction of a four-wheel drive option for the model.
The S-1800 and S-1900-were produced as both semitractors and straight trucks, while the S-1700 and S-1800 were used in the production of International Harvester bus chassis primarily for school bus use. The 3900 was produced until 2010. After 1994, the lower- 3700 was discontinued. In 1992, the instrument panel was redesigned, with the rest of the interior redesigned in 1995. Unlike the conventional, it was powered exclusively by diesel engines. In 1991, the 3600 semi-forward control variant was introduced; this was a chassis designed for the.
The International TerraStar is equipped with a 300 hp power MaxxForce V8 engine and the only no-hassle emissions technology available on the market which makes one of the most efficient trucks in the business. To reflect the corporate change of the company from International Harvester to Navistar International, S-series trucks saw changes in their badging alongside all International vehicles. A 4-speed manual was standard on the S1700 variants, while S1800 variants were equipped with a 5-speed manual; a 4-speed automatic was optional on all engines. All versions of the 3400 were powered by the 7. All three models share the same chassis, but they have different engines, axles and payload capacities. The 4000 series served as the replacement for the S1600 through 1900 Class 5-7 trucks with bus chassis rechristened the 3000 series , while the 8000 series replaced the S2100 and S2300 the wide-body S2200 was discontinued. In a major shift, for 1987, International became the first truck manufacturer to produce a medium-duty product line powered exclusively by diesel engines.
Following the discontinuation of the in 1975, the S series was designed with a model-specific cab, replacing the pickup-truck cab used for the Loadstar designed for the 1957 A series. Although much of the engine was located next to the driver like a transit-style bus, access from the front was also maintained via a traditional much-shortened hood. Unlike its S-series predecessor, the 3800 used an all-International lineup of diesel engines. The truck features a rugged design with a conventional cab configuration and is available with both single and sleeper cab options. In comparison to a conventional, the driver sat further forward, closer to the front axle.
As a replacement for the S series, Navistar introduced the 4000 series and 7000 series known as the and since 2008. Unsourced material may be challenged and removed. For the first time, the school bus chassis received a separate model designation; the S-1703 was replaced by the 3700; and the S-1803 was replaced by the 3800. The international ProStar is available with a choice of three MaxxForce engines that are combined with an aerodynamic design and a few efficient technologies to offer one of the lowest fuel consumption levels in the segment. Transmission, Hendrickson Suspension, S-Cam Brakes, 4.
Some photos may not depict actual unit for sale. As part of the redesign, the school bus chassis was given a more aerodynamic hood that better integrated the front bumper. With gross vehicle weight ratings between 52,350 — 80,000 lbs. Similar in style to the tilting hood introduced for the Loadstar in 1972, all S-series trucks were given a tilting fiberglass hood. Thanks to its heavy duty engine, the truck is able to tow up to 20 tons. You can also download it to your tablet or smart phone if required. In addition, the cowled chassis formed the basis for front-engine and rear-engine stripped chassis produced for bus applications.
A key event that would affect school bus manufacturing during the later 1990s was the completion of the acquisition of by in April 1995. In production for over 25 years, the S-series bus chassis was the longest-lived model line ever produced by International and the final Navistar product line developed by International Harvester. Along with completely straight frame rails, the chassis was designed with a flat-back firewall, allowing for body mounting with minimal design adaptations. The International TranStar line includes two different models namely the 8500 and 8600. The International WorkStar is available in five versions namely the 7300, 7400, 7500, 7600 and 7700. As with its predecessor, it again shared powertrain and chassis components with its conventional counterpart. The International CityStar can be used for a wide range of medium duty applications and its relatively compact dimensions give it a high maneuverability around the narrow city streets.
