VR-36HA — SERVICE INFORMATION
3.0 Drums and Main Frame
The front drum is designed to apply vibration and compaction
force to the operating surface for compaction. This vibration and
compaction force is produced when the vibrator shaft is rotated.
Maximum efficiency is achieved only when the engine is operated
at full throttle.
A single drive motor is mounted on the left side of the drum and
is shockmounted. This type of drive motor is designed for
maximum torque and power.
The vibrator is driven by a gear motor coupled to the vibrator
shaft. The vibrator assembly rotates inside of a sealed housing
containing oil to lubricate the bearings. This side of the drum is
also shockmounted.
