The Caterpillar 426B loader backhoe was introduced in 1992 in England as the replacment for the Caterpillar 426/426 II. Production began in the USA in 1994.

[edit] Features

The 426B has a Cat 3054 turbocharged engine producing 79 flywheel horsepower (FWHP). It comes standard with an excavator-style boom, thermal starting aid, self-adjusting brakes, and a hydraulic pump that delivers fluid at a rate of 41 gallons (155 L) per minute (GPM) at a system pressure of 3,000 pounds (1,350 kg) per square inch (PSI) (20,684 kPa). It also has modified hydraulics and a redesigned operator’s compartment.

The 426B was manufactured in England, with a 5YJ serial number prefix, and in the USA, with a 6KL prefix.
