Description
Koken S.O.D.H. System is the two dogs (pawls) are located in the ratchet body so that the dogs (pawls) and springs are held securely in place, allowing the reversing lever and dog (pawl) to switch smoothly. The torque load on the gear is transmitted vertically to the dog (pawl) and in turn, down the ratchet handle. This mechanism locks gears tightly in place while torque is being applied, thus avoiding any gear slippage.
