Insert each bent end of the snap-ring pliers into the holes on the existing snap ring, if there is currently a snap-ring still on the dryer wheel shaft. The snap-ring pliers have pointed jaws that fit snugly into the holes on the snap ring.
Squeeze the snap-ring pliers handles slightly to open the jaws and spread the ring apart. Pull the ring away from the dryer wheel shaft.
Release the plier handles, and allow the jaws to close. Take the old snap-ring off the pliers. Position the holes of a new snap-ring onto the ends of the snap-ring plier jaws.
Open the snap-ring by squeezing the plier handles slightly. Hold the snap-ring open and maneuver it over the dryer wheel shaft until it is over the notch on the shaft. Release the plier handles, and remove the pliers.
