Abstract
A method of manufacturing a camshaft for an engine having cylinder head bolts, includes providing a tube, placing at least one separately produced cam in a position on the tube along an axis of the tube, fastening the cam to the tube and pressing at least one external indentation into the tube at a part of the circumference of the tube. The indentation is pressed transversely toward the tube axis into inner and outer surfaces of a wall thickness of the tube at an axial location along the tube axis and does not encircle the tube. The indentation is also disposed along the tube and beside the cam with no part of the indentation being covered by the cam and the indentation being sufficiently deep to allow access to the cylinder head bolts of the engine.
