JCB Vibromax 255, 265 Tandum Roller Service Manual – 220 Pages

The Vibromax 255 and Vibromax 265 Series vibratory roller is a redesign of the 253/263. The machine remains a 2.5 metric ton, tandem drum machine with articulated steering, hydrostatic drive and a hydraulically driven vibration system. The 255 has a 1000 mm (39 inch) drum width while the 265 is a 1200 mm (47 inch) drum width version. These machines are also offer with a K version which is a combination roller built with pneumatic tires in place of the rear drum.

A Kubota D1403B, water cooled, three cylinder in-line diesel engine, mounted in the rear chassis, provides the power for the machine. The standard engine has a 29.0 Net Horse Power rating at 2600 RPM. An optional high horsepower Kubota D1403B (37 horsepower) is also available. Both engines meet the latest exhaust emissions standards.

A Sauer Sunstrand hydrostatic propulsion pump provides oil for the front and rear Poclain, fixed displacement, drum drive motors in a parallel path. On the K model combination roller there are three propulsion motors in parallel. Propulsion system controls are enhance with the addition of a high and low operating range. The motors are on the right hand side of the drums and connect directly to the drum.

The vibration system consists of a fixed displacement gear pump mounted to the back of the propulsion pump. This gear pump drives the two gear motors (one on each drum, left hand side) in a series flow path, with options of vibration to the front drum only, rear drum only, both drums or neither drum. Oil from the vibration circuit passes through an air to oil cooler at the engine radiator. The exciter shafts and the drum bearings are oil lubricated, eliminating the need for grease zerks.

Pressure testing of the hydraulic system has been simplified by the location of a test station inside the left side access door. Pressure testing of the drive, charge, vibratory and steering systems can be perform from this one location.
