ISX electronics adds performance and efficiency New Cummins 14-liter diesel will be offered in and fleet owner-operator ratings

The Cummins ISX Series brings the company's Interact System advanced electronic controls to its largest on-highway diesel engines. Similar to the 14-liter Signature 600, the new ISX also features dual overhead cams and an integrated engine brake system, as well as a variable output turbo that improves low-speed boost.

The first two ratings in the new series are the ISX 565 and ISX 600, which are aimed at the owner/operator market. Both models generate 1,850 lb.-ft. of peak torque, but can be spec'd with Smart Torque technology to limit torque in lower gears, allowing them to be used safely with lighter, lower-cost drivetrain components. Although not yet officially announced, 400- and 450-hp. versions more suitable for fleet applications are expected in the near future.

Cummins has already introduced the Interact System for its 5.9-liter, 8.3-liter, and 11-liter diesel engines. The system's advanced electronics can monitor and record operating data, provide diagnostic and prognostic information, and allow engine operating characteristics to be tailored to user requirements. It also provides J1708 and J1939 data links for connections to other onboard information systems and electronically controlled components.

The Tundra from Toyota gives the company its first full-size pickup to compete with the big pickups from Dodge, Ford, and GMC.

Today's more powerful engines may be helping put drivers behind the wheel. But they're putting added stress on drivetrain components as that power is conver ted to road speed. That's the word from Dana Spicer Driveshaft Div.

According to Bob Morgillo, warranty technical manager, there has been a growing trend on the part of fleets to spec high torque rise engines combined with direct-drive transmissions and low rear-axle ratio (less than 3.73) to increase efficiency.

These so-called fast axles require higher startup torque, which must pass through the driveshaft. Unless fleets beef up the spec on their driveshafts to handle the increased torque, Morgillo warns that they may experience premature driveline failure in the form of broken universal joints, brunneled universal joints, and decreased life of the driveline.

The first full-service dealers for the new line of Bering Class 3-8 trucks were introduced at the American Truck Dealers convention. Fifteen dealerships, from Ohio to Florida, will be adding Bering, according to president and CEO William R. Anderson Jr. This inaugural group is the first of a total of 60 eastern dealership slots.

Neway Anchorlok has added two heavy-duty models to its line of trailer air-ride suspensions. Designed for low-profile trailers, the RLU-250 and RLU-250-FMT are rated at 25,000 lb.

With a two-pin bushing design, the RLU-250 is said to provide roll stability, as well as better tire life and vehicle tracking. It can be used for liftable axle applications.

The RLU-250-FMT is intended for double-drop trailers; cargo capacity and deck space are maximized when the unit is combined with the RLU-250.

Both suspensions use common air springs and shock absorbers; Neway's E-Z Align field axle realignment is standard.

In conjunction with Dana Spicer Trailer Products Div., Neway now also offers an integrated trailer air-ride suspension axle package.

Standard on the iPAC system are an RL-228 suspension, Anchorlok Gold Seal spring brakes, and a 71.5-in.-track Spicer axle that includes Spicer Silver foundation brakes and Spicer automatic slack adjusters. Options include a 77.5-in. track axle, Anchorlok's Life Seal spring brakes, and Carlisle MB21 foundation brakes.

The suspension and axle are attached via Neway's NEWeld axle connection. Since there's no weld on the axle tube inside the brake spiders, thinner wall axles and short camshafts can be used, which means less weight.

The iPAC is available in top-mount and underslung designs in 22,500- and 25,000-lb. ratings.

Chicago Rawhide has introduced a long-life version of its Scotseal wheel seal that is geared to withstand the tougher operating environment created by today's synthetic lubricants.

The Scotseal longlife is made from a hydrogenated nitrile material, which has higher temperature capabilities and is more compatible with the harsh additive packages found in synthetic lubes. Based on the one-piece, multi-lip design of the Scotseal, the new unit features an additional dirt lip. This four-lip design keeps out road grime even longer, providing extra defense against the environment

At a recent press conference at its Danville, Va., plant, Goodyear unveiled its new G397 LHS radial steer tire. Designed for linehaul service, the tire features a new casing supported by a "super tensile" steel belt package and a polyamide top belt, as well as a wear-resistant tread compound.

"From the ground up, we've applied a new philosophy of tire design to produce the G397 LHS," stated Mike Thomann, marketing director-commercial tires.

Thomann said the tire's monofilament polyamide top belt is a key to the tire's "toughness." In concert with the high-tensile steel belts, the top belt serves as a protective barrier against moisture, punctures, and tears. This reduces the need for "buzzout" repairs, thereby increasing the tire's retreadability.

In addition, the new axle-specific wear-resistant compound and a new tread pattern combine to enhance cornering and control. The tread surface of the new tire has lateral slots and sipes to improve traction as well as even tread wear. And the shoulder-rib design includes a pressure-distribution groove to reduce cupping wear.

The G397 LHS is built on Goodyear's premium fuel-efficient ECD casing. Other design features include a tear-resistant compound for the bead area and a new mold shape that equalizes contact pressure for more even wear. It's currently available in 295/75R22.5 and 11R22.5 sizes, and will come in 285/75R24.5 and 11R24.5 sizes later this spring.

Heading the list of refinements to Caterpillar's truck engine lineup is the introduction of the ADEM 2000 (Advanced Diesel Engine Management) electronic-control system.

Standard features of the Integral Arm steer axle family include a forged one-piece knuckle design for increased strength and component reliability. The standard beam stop is 3.5 in. Dana Spicer's LMS Hub System is available as an option. As part of the Roadranger System of products from Dana and Eaton Corp., they are backed by experienced and accessible drivetrain consultants.

The latest addition to Thermo King's Whisper Edition line increases deep-frozen capacity by about 20%, providing 30,000 Btu/hr. for temps as low as -20 degrees F.

Developed especially for longer, thinner-walled trailers, the Magnum unit features a compressor with 80% fewer moving parts than standard refrigeration compressors. The parts-reduction for the S391 is accomplished by using two precision-made helical rotors.

According to Thermo King, the Magnum Whisper Edition can pre-cool down to -20 degreees F twice as fast as traditional refrigeration systems, which means reefers can be back in operation more quickly.

Magnum Whisper Editions also feature Smart Set technology, which provides temperature balance for fresh cargo and reduced fuel consumption.
