  • Ratchet wrench with sealed reversing lever
    Patent number: 6125722

A pawl-engaging reversing lever is insertable through an opening in the ratchet body from the cavity and has a flange dimensioned to be trapped between the body and the pawl. A seal between the reversing lever and the ratchet body is provided by an O-ring seated in a groove in the outer surface of the reversing lever hub.
