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 a Rexroth 2 speed drum drive motor and a 2 speed axle drive motor in a parallel path. The Rexroth drum motor is mounted on the left side of the drum, drives through a L&S planetary gearbox and is isolated from the drum by rubber buffers. This arrangement use in the heavy roller models with a great deal of success.

The Vibromax VM46 Single Drum Roller axle drive motor is attach directly to the gearbox incorporated into the rear axle. The vibration system on the VM46 uses a Rexroth gear pump mounted directly behind the propulsion pump. The vibratory pump supplies oil through the vibration control valve to a Rexroth hydrostatic motor mounted at the right side of the drum. This operates the exciter shaft at a single frequency of 32 Hz or 1920 vibrations per minute on both the smooth drum and pad foot versions. A steering pump, mounted to the rear of the vibratory pump, provides the oil needed for steering.

Steering Pump

The steering pump also acts as the charge pump in the propulsion system. The steering pump draws oil from the reservoir, passes it through the steering control valve, through the inline hydraulic filter, and into the charge circuit. This machine comes standard with parking brakes at both the front drum and the rear axle.

A spring applied-hydraulically released multi disc brake is part of the drum drive motor gearbox. The axle uses a spring applied hydraulically released multiple disc brake at each axle shaft. Pressure testing has been made easier by placing all the test ports at a centrally located test station under the engine hood. The electrical system of the Vibromax VM46 Single Drum Roller consists of a 12 volt battery, starter, alternator system, optional lighting and standard instrumentation.
