Make sure the reaction arm is positioned correctly. (Refer to Dwg. 01).
The reaction arm can be positioned numerous places within a 360O circle. However, for the arm to
be correctly positioned, it must be set within a 90O quadrant of that circle. That quadrant is the area
located between the protruding square drive and the bottom of the housing away from the swivel
inlets. It will always be toward the lower half of the housing and on one side of the housing when
tightening and the other side when loosening.
Square Drive Position for Loosening and Tightening(Dwg.02)
The position of the square drive relative to the shroud determines whether the action will tighten or
loosen the nut. (Refer to Dwg. 02 for application examples).
The power stroke of the piston assembly will always turn the square drive toward the shroud.
