Patent ID: 8516702

Claim:
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 is rotatably arranged about a first rotation axis and the second drum is rotatably arranged about a second rotation axis parallel to but not coincident with the first rotation axis, the method comprising: forming a first positioning hole in a first position of the first drum and forming a second positioning hole in a second position of the second drum; forming a third and a fourth positioning hole in a housing of the motor-vehicle gearbox, the third and fourth positioning holes being aligned with the first and second positioning holes of the first and second drums, respectively, when the first and second drums are in the predefined relative angular position; 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, the locking including engaging the first and second positioning holes with a locking device, and wherein the locking includes using the locking device having a first pin insertable into both the first positioning hole of the first drum and the third positioning hole of the housing and a second pin insertable into both the second positioning hole of the second drum and the fourth positioning hole of the housing; and disengaging the locking device from the first and second positioning holes of the first and second drums once mounting of the gear control device is completed.
