ABSTRACT:
An apparatus for lubricating a wheel hub is disclosed. The apparatus generally comprises a wheel hub, wheel bearings mounted within the bore of the wheel limb for supporting an axle, a hub cap forming a closure cap for the outer end of the wheel hub, an outwardly yieldable bearing seal positioned at the inner end of the wheel bearing and an annular clamp for retaining the seal but allowing sections of the seal to yield. In operation, lubricant under pressure is introduced into the hub cavity from the outer end. The lubricant is then forced from the outer end to the inner end of the hub where the excess lubricant is discharged by the yieldable seal.
