Pass through timing pin system

A method, comprising:

• providing an internal combustion engine having a cylinder head structure with a timing pin hole therein, the internal combustion engine having a camshaft and a crankshaft each rotatably mounted therein, the camshaft having a longitudinal axis with a first shaft that spans along at least a portion of the longitudinal axis, the first shaft having an outer annular wall that defines a first opening that extends towards the longitudinal axis, the internal combustion engine having a cam bushing located in a camshaft cavity of the cylinder head structure, the bushing having a bushing clearance hole;
• inserting a timing pin through the timing pin hole, the bushing clearance hole, and into the first opening of the first shaft of the camshaft to position the camshaft in a camshaft timing position;
• rotating the crankshaft to a crankshaft timing position for setting a static timing of the crankshaft relative to the camshaft;
• and
• removing the timing pin from the timing pin hole, the bushing clearance hole, and the first opening of the first shaft of the camshaft.

A system, comprising:

• a cylinder head structure for an internal combustion engine, the cylinder head structure having a timing pin hole and a camshaft cavity therein;
• a camshaft for the internal combustion engine that is rotatable to a camshaft timing position, the camshaft having a longitudinal axis with a first shaft that spans along at least a portion of the longitudinal axis, the first shaft having an outer annular wall that defines a first opening that extends perpendicularly towards the longitudinal axis;
• a cam bushing located in the camshaft cavity, the cam bushing having a bushing clearance hole;
• and
• a timing pin configured for insertion through the timing pin hole, the bushing clearance hole, and into the first opening of the first shaft of the camshaft to lock the camshaft in the camshaft timing position.
