Caterpillar has refined the design of its skid steer and compact track load- ers and designated the line B-Series 3. Models include 216B3, 226B3, 236B3, 242B3 and 252B3 skid steers and 247B3 and 257B3 compact track loaders. A redesigned dead-engine lower valve provides an easier-to-use, more-positive means of lowering the lift arms if the machine should run out of fuel or stall with the arms raised. A new lever-action handle acts di- rectly on the hydraulic relief valve. A new single ECM has been moved from the lower frame to the back of the cab and provides easier access to electrical service points as well as simplified wiring and a reduction in the number of connections. Cat added power to the 242B3 skid steer and 257B3 compact track loader with a 71-horsepower engine, which in- creases net power by 25 percent, and a hydraulic system with about 40 percent more standard flow, at 22 gpm.
The Cat 336F H Hybrid hydraulic excavator will soon be powered by a Tier 4-Final Cat C9.3 ACERT engine rated at 303 horsepower.
The new Cat 966M, 966M XE, 972M, and 972M XE wheel loaders meet Tier 4-Final emissions regulations with a combination of combustion strategies and after-treatment components.
