Abstract
A retainer for the drive shaft of a hydraulic torque wrench has an eccentric pivotably connected to the free end of the shaft which can be pivoted between an unlocked position and one or more locked positions and locked in any of the positions with a plunger. In the unlocked position, the eccentric does not overlap a bearing of the wrench so that the shaft and eccentric can be withdrawn axially from the wrench drive head. In the locked position(s), the eccentric overlaps and abuts an axial face of the bearing so that the eccentric cannot be drawn into the bearing, thereby securing the shaft against axial movement out of the wrench drive head in the direction from the eccentric toward the bearing.
