  • Device for detecting metallic particles in lubricant
    Patent number: 5066071
    Abstract: A device for visibly detecting the presence of metallic particles in the oil of the hub of a motor vehicle such as a truck. The hub has a transparent portion and an access hole with a plug therein. In this invention the plug carries a flat strip or flag of magnetic material pivotally suspended from the axial inner end of the plug. As the hub and the plug rotate the magnetic strip can remain relatively stationary to collect any metallic particles in the oil. The strip is preferably light colored to show the metallic particles and is readily viewable through the transparent portion of the hub.
