JCB Vibromax 255, 265 Tandem Roller Service Manual

Product Overview

The JCB Vibromax 255 and 265 series are advanced vibratory rollers, featuring a redesign from the previous 253/263 models. These machines maintain a 2.5 metric ton tandem drum configuration with articulated steering, a hydrostatic drive, and a hydraulically driven vibration system. The Vibromax 255 model showcases a 1000 mm (39 inches) drum width, while the Vibromax 265 offers a larger 1200 mm (47 inches) drum width. Additionally, a “K” version is available, which substitutes the rear drum with pneumatic tires, providing a combination roller option.
