Abstract: A hood module for attachment on a cylinder head of an internal combustion engine may include a hood body comprised of plastic and a bearing bracket comprised of metal as a rotatable holder for a camshaft in the hood module. The bearing bracket may be attached to the hood body with position accuracy by a joint connection so that the bearing bracket is aligned for attachment on the cylinder head through the hood body. In some examples, a joint element in the form of a sleeve may be used as part of the joint connection between the bearing bracket and the hood body.”
