A relubricatable idler bushing assembly includes an idler bushing having a hub which is dimensioned to receive an idler pulley. The idler bushing is journaled to an inner bushing by bearings which are disposed in fluid communication with a lubricant passageway. The inner bushing is mounted on a spindle adapted to mount the idler bushing assembly to a support surface. The spindle includes and axial passageway and a radial bore communicating the axial passageway with the exterior of the spindle. One end of the spindle is adapted to be connected to a source of lubricant under pressure for supplying the lubricant to an axial passageway. The radial bore is communicated through a radial bore of the inner bushing with the lubricant passageway to allow lubricant supplied to the spindle to be flow to the lubricant passageway.
