We are pleased to bring a solution to the long standing problem of failed gearboxes on electronic actuators. Gearboxes fail when the VNT mechanism sticks – the failure mode is either through power overload on the motor or failure of the gear parts.
For a 100% quality repair, Melett recommends replacing thewhole gearbox, rather than repairing the internal parts. It is difficult to accurately diagnose what condition the gears or motor are in, or how close they are to failing. Attempting to repair the individual gearbox components can result in premature failure once fitted back onto the turbo.
