Caterpillar CT660 vocational truck is based on International’s PayStar 5000i series and will use Navistar diesels and offer Cat’s own automatic transmission. The result of a manufacturing agreement between Cat and Navistar International, the trucks will be sold and serviced exclusively through Cat’s North American dealer network, with production beginning after ConExpo for delivery later in the year.
Initial engine options will include a Cat CT11 with ratings from 330 to 390 hp, and a CT13 at 410 to 475 hp. Both are expected to be MaxxForce 10.5- and 12.4-liter diesels adapted for use in the Cat trucks.
In 2012, Cat will offer a CT15 with 435 to 550 hp. This 15-liter engine will be Cat’s version of Navistar’s upcoming MaxxForce 15, which uses a Cat C15 block and other “iron” components with Navistar fuel and air systems.
Cat’s CX31 torque converter-style automatic transmission will be an option. Already used in Cat machinery, the CX31 will have three locations for rear power take-off mountings. Caterpillar will also offer other vocational transmission options, including Eaton manual and automated-manual transmissions.
Caterpillar has expanded its heavy-duty line of Class 8 work trucks with the new Cat CT681 vocational truck, a set-forward-axle model designed for customers who prefer a longer wheelbase truck or who must comply with restrictive load limitations on bridges and roads.
All-wheel drive versions of Western Star 4700SB (setback front axle) come in 4x4 and 6x6 versions.
