Shut off the water supply to the hydrant. Lift the handle to the open position.
Remove the two linkage screws and rotate handle out of the way. Unscrew
and remove the pivot block from the brass operating rod. Loosen the packing
nut. Remove the head casting using two pipe wrenches, one on the pipe and
one on the head casting. Remove the operating rod assembly by gripping the
steel rod (not the brass stem) with vise grips and prying up. To remove the
plunger, use either pipe wrenches or vise grips. When reinstalling the
operating rod assembly in the hydrant, first partially screw the pivot block onto
the brass stem to protect the threads. Use a soft mallet or a block of wood to
drive the plunger into the valve seat. Applying a lubricant that is safe for
rubber such as silicone on the plunger rubber will aid in seating the rubber.
Remove the pivot block from the brass stem and reinstall the head casting.
Adjust the linkage to the proper tension.
