Abstract
A wrench is presented which includes a power cylinder having a piston rod extending therethrough. An anchor or reaction assembly comprising an anchoring ring and attached anchor rod is adjustably attached to the piston rod to permit connection of the anchoring ring to a nut spaced from the nut to be turned. A wrench assembly comprising a preferably arcuate lever arm with a ratchet assembly is pivotably connected to the power cylinder. The wrench incorporates a ratchet pawl which engages a drive mechanism. A control lever can disengage the pawl from the drive mechanism, and a latch mechanism retains the control lever and pawl in a disengaged position until released.
