<p>A reversible ratchet wrench (10) has a ratchet body (11) with a cavity (15) receiving the ratchet assembly (20). A pawl-engaging reversing lever is insertable through an opening in the ratchet body from the cavity (15) and has a flange (46) dimensioned to be trapped between the body (11) and the pawl (31). A seal (59) between the reversing lever (40) and the ratchet body (11) is provided by an O-ring (50) seated in a groove (45) in the outer surface of the reversing lever hub (44). A cover plate (55) closes the cavity (15) and cooperates with the pawl (31) and the flange to retain the reversing lever (40) in place.</p> |
