A body of lubricant acting also as a coolant is confined by a housing to the base of a vibratory compactor in direct contact with the, planar bottom portion of the base. Upwardly inclined end portions of the base accommodate tilting of the machine in one direction for installation of wheel assemblies or in the other direction to drain all of the lubricant from the housing. A vibration generating eccentric rotor within the, housing mounts flow directing blades to effect misting of the lubricant during vibration and direct it toward critical lubricating points.
