Method for the mounting, in the correct relative angular position, of a pair of rotary drums of a double-drum sequential gear control device for a motor-vehicle gearbox

摘要

A method of mounting a first drum and a second drum of a double-drum sequential gear control device for a motor-vehicle gearbox in a predefined relative angular position, wherein in a mounted condition the first drum and the second drum are rotatably arranged about respective rotation axes parallel to but not coincident with each other, includes forming a first positioning hole in a first position of the first drum, forming a second positioning hole in a second position of the second drum, arranging the first drum and the second drum in the predefined relative angular position, locking the first drum and the second drum in the predefined relative angular position by engaging the first positioning hole and the second positioning hole with a locking device, and unlocking the first drum and the second drum once mounting of the gear control device is completed.
