Abstract
A method without a calibration step produces a camshaft adjuster including a stator, a rotor rotatable relative thereto and a control valve, wherein the rotor and/or the stator is or are produced according to a powder-metallurgical process, wherein the stator in the region of a fitting surface for contacting the camshaft and/or the rotor in the region of a fitting surface for contacting the camshaft and/or in the region of a fitting surface for contacting the control valve and/or the control valve in the region of a sealing surface is or are produced having a tolerance so that a clearance fit with a maximum clearance of 100 μm is formed between the fitting surface for the camshaft and the camshaft and/or between the fitting surface for contacting the sealing surface of the control valve and the sealing surface of the control valve.
