System Description

Triple-cone synchronizer

Triple-cone synchronizers are adopted for the 1st and the 2nd gears to reduce operating force of the shifter lever.


  1. 1st main gear
  2. 1st-2nd coupling sleeve
  3. Insert key
  4. Outer baulk ring
  5. 2nd main gear
  6. Synchronizer cone
  7. Inner baulk ring
  8. 1st-2nd synchronizer hub

Reverse gear noise prevention function (synchronizing method)

Reverse gear assembly consists of reverse input gear, return spring, reverse baulk ring, and reverse output gear. When the shifter lever is moved to the reverse position, the construction allows smooth shift operation by stopping the reverse idler shaft rotation by frictional force of synchronizer.
