Abstract
Abstract A device to lubricate bearings mounted within a wheel hub. A main body includes a grease fitting at one end which is in fluid communication with a passage opening between a pair of O-rings mounted to the main body of the lubricator. A bracket on the lubricator locates the O-rings on the opposite sides of the bearing being lubricated. In an alternate embodiment, a pair of ridges are provided on the main body in lieu of the O-rings.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
196 words
A device for lubricating a hub and bearings mounted therein comprising: a one-piece main body sized to fit through said bearings and into said hub, said main body having a first end and second end; a grease fitting mounted on said first end to receive and apply a flow of grease through said main body; passage means in said main body and having an outlet opening between said first end and second end and aligned and in communication with said fitting to receive a flow of grease and direct same out of said main body to the bearing being lubricated; sealing means on said main body and located adjacent the bearing being lubricated when said main body is located in said hub and being operable to stop grease from flowing out of said hub; and locating means connected to said main body and having a first surface adjustable to and from said sealing means to locate said sealing means on opposite sides of the bearing being lubricated when said main body is positioned within said hub and said first surface is in contact with said hub while also positioning said outlet adjacent the bearing being lubricated.
