Essentially, when the gearbox cooks the oil several times, it loses its lubricating properties, which leads to a weaker oil-film and accelerated wear. The motor's shaft is attached to one end of the gearbox and through the internal configuration of gears of a gearbox, provides a given output torque and speed determined by the gear … if (d.getElementById(id)) return; The M20 gearbox is a lower torque variant of the M32.
