An elongated cylindrical body is provided having a first end portion including an external surface of substantially circular cross section and slightly tapering in diameter toward the terminal end of the first body end portion. The body includes a second diametrically enlarged end portion and a grease passage extends longitudinally through the body and opens endwise outwardly through the axially ends of the first and second end portions. A grease fitting is secured in the end of the passage opening outwardly of the second body end portion and the tapering first end portion of the body is designed to be lightly wedgingly seated in the outer end of an access bore with a high pressure grease gun operatively coupled to the grease fitting for introducing grease into a cavity into which the inner end of the access bore opens. A build up of low pressure grease within the cavity is sufficient to force the tapered first end portion of the body from seated engagement in the outer end of the access bore and to thereby allow excess grease introduced into the cavity to escape therefrom via the access bore.
