TECHNICAL FEATURES TORQUE CONVERTER STRUCTURE
Pump The pump, directly connected to the crankshaft, converts engine output (torque) into oil flow
Turbine Receiving the oil from the pump, the turbine transmits the torque to the transmission by way of the primary drive gear,
Stator The stator changes the direction of the oil flow drained from the turbineIt drains the oil toward the pump Stator Shaft
It transmits the stator rotation to the one-way clutch
Stator One-way Clutch
The stator one-way clutch locks the stator at stalling and it releases (rotates) the stator at coupling (page 2-8) Inner Collar The inner collar, prevented from turning by the stopper pin fixed on the crankcase, stops H1e rotation force at stalling, which is transmitted from the stator by way of the one-way clutch Engine Brake One-way Clutch When the engine braking is applied, the engine brake one-way clutch directly transmits the input torque from the primary drive gear to the crankshaftThis allows the machine to slow down by engine braking Seal Ring and Seal Collar The seal ring and seal collar are provided to prevent oil leakage
