    2. Reverse Synchromesh Mechanism


      1. The reverse synchromesh mechanism consists of 2 shifting keys, a shifting key spring and a shifting key return spring.

  2. OPERATION


    1. Reverse Synchromesh Mechanism


      1. While shifting into 5th, the 2 shifting keys move in unison with the hub sleeve (F1). With "A" acting as the fulcrum, the 2 shifting keys move to push the synchronizer ring only for the amount of the lever ratio (F2). The shift effort can be reduced only by this amount.

      2. While shifting into reverse, the 2 shifting keys move in unison with the hub sleeve (F1). With "B" acting as the fulcrum, the 2 shifting keys move to push the synchronizer ring (F2). As a result, a brake is applied to the rotation of the counter shaft and gear noise is prevented.
