The gear layout is a 4th gear direct coupling and 5th gear overdrive type. All forward gears have been made the constant mesh type, achieving excellent quietness.
The reverse gear and hub sleeve have been combined into a single part to achieve weight reduction.

A sealed ball bearing is used on the support portion of the input shaft and output shaft to ensure sufficient durability.
A cylinder roller bearing is used on the support portion of the counter gear, which supports a heavy load, to ensure sufficient support rigidity and durability.
A needle roller bearing is used in each gear to reduce torque loss due to sliding resistance.
