JCB Vibromax 752 Tandum Drum Roller Service Manual – 190 Pages

In the fall of 1999 Vibromax introduced the new 752 series tandem drum vibratory roller. The Vibromax 752 Tandum Drum Roller has a significant improvementin drive system. The operating weight is 18,728 lbs. (8,495 kg) while keeping the same 66 inch (1675mm) drum size. The roller uses the Cummins 3.9 liter 4 cylinder engine. The new engine is tune to meet the latest emissions standards.

A Mannesman Rexroth variable displacement, axial piston hydrostatic pump, used for machine propulsion, mounts to the flywheel end of the engine. It provides oil to the front and rear drum drive motors in a parallel path. The Rexroth 2 speed drum drive motors are mounted on the left side of the drums, drive through L&S planetary gearboxes, and are isolated from the drum by rubber buffers. This arrangement is use in the heavy roller models with a great deal of success.

These machines come standard with parking brakes at both the front drum and the rear drum. See the table of content of the Vibromax 752 Tandum Drum Roller Service Manual for more details
