The present invention relates to a fan, to a method, and to a device for assembling the fan. The fan has an axis of rotation, which is connected to a dog, wherein the dog is connected to a fan wheel, wherein the dog, in a first number of contact surfaces, is in contact with additional contact surfaces of the fan wheel, wherein the dog and/or the fan wheel have more than the first number of contact surfaces and/or additional contact surfaces, wherein at least two contact surfaces have different height positions with respect to a central axis of the dog and/or the fan wheel.
