International’s WorkStar

Navistar has added new waste-collection features to its line of International WorkStar vocational trucks, and the DuraStar joins its heavy-spec cousin in being spec’able for the waste industry.

Cab air suspension is standard on WorkStar, optional on DuraStar. The cab, made of double-sided galvanized steel, has a design focused on easy entry and exit, the maker says, to increase driver productivity and reduce driver fatigue. Both WorkStar and DuraStar cabs come with a five-year limited warranty.

They can both be spec’d to accommodate stand-up, right-hand drive (SRD) configurations. With the DuraStar’s sloped hood, SRD conversions work especially well, says Navistar, providing operators with excellent sight lines forward and side-to-side.

The WorkStar’s cooling system is mounted above the frame rail, which not only protects the radiator in off-highway environments like landfills but also allows for FEPTO (front-end power take-off) mounting without having to put a hole in the radiator.

International mounted the DuraStar’s cooling package in mega-brackets at the front of the frame rails. This design, adopted from the severe-service PayStar 5900 SBA, is said to allow for excellent visibility in applications that don’t need a PTO up front.

Standard, wide-track front axles on both trucks allow for greater wheel cut and a shorter turning radius.

All 2010 MaxxForce diesel engines specified for the waste collection industry — from its mid-range MaxxForce DT, MaxxForce 9 and MaxxForce 10 to its heavier-duty MaxxForce 11 and MaxxForce 13 — are wet-sleeved engines, allowing for rebuilds without removing them from the chassis. The smaller engines go to 350 hp while the 11- and 13-litre motors have ratings as high as 475 hp.
