DetailsTorque springs are important for the transmission set-up. The spring exerts pressure onto the torque driver and so strongly influences the variator’s “shifting” characteristics. You’ll know that it’s necessary to go for a stronger spring when the drive belt keeps slipping, the variator doesn’t shift smoothly within the ideal rpm range or the engine keeps running below the ideal rpm range despite using lighter rollers. After replacing the torque spring, the variator will have to be readjusted.
