1, The hydraulic pressure is applied to the forward clutch and the start clutch, and the sun gear drives the torward
clutch.
2. The torward clutch drives the drive pulleV shaft. which drives the driven pulley shaft linked by the steel belt.
3, The driven pulley shaft drives the secondary drive gear, via the start clutch.
4. Power is transmitted to the secondary driven gear, which drives the final driven gear.
NOTE: The working hydraulic pressure on the movable face of each shaft depends on the throttle opening position.
