The ratchet 10 includes a body 14 with a cavity 16 receiving pawls 20, 22 and ratchet gear 24. A cover plate 50 closes the cavity. A reversing lever 70 is operably coupled with the pawls for selecting the drive direction. The lever has a first recess for receiving a spring-biased ball 156 in a first lever position corresponding to a first drive direction. A second recess receives the spring-biased ball in a second lever position corresponding to a second drive direction. The reversing lever has a raised portion between the first and second recesses which includes a peak 166 and first and second ramps 162 leading to the recesses. The ratchet may include a through bore with a first bore opening proximate to the reversing lever and a second bore opening distal to the lever. The reversing lever may further include first and second stops to limit rotation. A spacer may additionally be placed between the reversing lever and the cover plate. |
