Abstract
A method is described for manufacturing a multi-component camshaft assembly having an internal mechanism for enabling relative angular movement of individual cams of the assembly. In the invention, the cam surfaces are machined after the individual components of the camshaft assembly have been assembled to one another.
Claims8
A method of manufacturing a multi-component camshaft assembly having an internal mechanism for enabling relative angular movement of individual cams of the assembly, the method comprising the steps of assembling relatively movable components of the camshaft assembly to one another, locking the relatively movable components of the camshaft assembly to one another, machining cam surfaces while the assembled components of the camshaft assembly are locked relative to one another, and releasing the assembled components to enable them to move relative to one another after the cam surfaces have been machined.
A method as claimed in claim 8, comprising pumping a fluid under pressure into interior spaces of the camshaft assembly during the machining of the surfaces in order to prevent ingress of debris into said interior spaces.
