Abstract: An earth boring bit with sealed cutter bearings has lubricant flow passages which extend from an interior cavity of the bit body to spaces located between bearing shafts and rotary cutters. A lubricant compensator has an elongate body defined by a tube which has a first end disposed in one of the flow passages and a second end which extends into the interior cavity. A piston is initially disposed in the second end, biased to apply pressure to lubricant located in the flow passages. The first end has a section for receiving the piston when lubricant is expelled from within the tube. Apertures extend through a sidewall of the tube, spaced apart from the section in the first end and in fluid communication with the flow passages. The apertures, the flow passages, and the spaces located between bearing shafts and rotary cutters are sized for passing drilling fluid.
