Abstract:

A method of assembling a camshaft may include locating a first lobe member of the camshaft on a first shaft and inserting a locking pin into a first bore in the first lobe member and into a second bore in the first shaft. The locking pin may include a first recess extending into a first end thereof defining a first annular wall. A first retaining member may be forced into a first recess.

Abstract:

A camshaft assembly method may include locating a first lobe member of a camshaft assembly on a first shaft of the assembly. A locking pin may be inserted into a first radial bore in the first lobe member and a second radial bore of the first shaft. The locking pin may have an annular wall defining a pin bore extending from a first end of the locking pin to a second end of the locking pin. A deforming member may be forced into the pin bore to displace the annular wall in an outward radial direction and into a frictional engagement with the first radial bore. The forcing may include a deforming member entering the pin bore at the first end of the locking pin and exiting the pin bore at the second end of the locking pin.
