JCB Vibromax VM116,146,166,186 Single Drum Roller Service Manual – 194 Pages

This manual introduces the new Vibromax 6 series single drum rollers. Included within the pages of the book are materials covering the Models Vibromax VM116, VM146, VM166, and VM186. The new rollers all use the Cummins 5.9 liter 6 cylinder engine. The engines are turbocharge with charge air cooling. All of the new engines are tune to meet the latest EPA emissions standards.

A Sauer Sundstrand Series 90 variable displacement, axial piston hydrostatic pump, used for machine propulsion, mounts to the flywheel end of the engine. It provides oil to a 2 speed drum drive motor and a 2 speed axle drive motor in a parallel path. The drum motor is mounted on the left side of the drum and drives through a planetary gearbox and is isolated from the drum by rubber buffers. The axle drive motor is attached directly to the rear axle which is a no-spin design.

The vibration system uses a Sauer Sundstrand Series 90 hydrostatic pump similar to the propulsion pump and mounted directly behind the propulsion pump. The vibratory pump supplies oil to a Series 90 hydrostatic motor mounted at the right side of the drum. The new models Vibromax VM116, VM146, VM166, and VM18 operate at frequencies of 1740 or 2160 vibrations per minute on both the smooth drum and pad foot versions. A steering pump, mounted to the rear of the vibration pump, provides the oil needed for steering. The steering pump is also a second charge pump in the propulsion/vibration circuit. 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. The charge pump draws oil from the reservoir, joins the steering oil at the filter, passes it through the filter and into the charge circuit.

The Vibromax VM116, VM146, VM166, and VM18 come 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.
