Chain drive system having anti-rotation features between pivot pin and guide link and related assembly method

A chain drive system comprising:

• a plurality of chain links, each of the chain links having a link body that defines a pair of chain link apertures;
• a plurality of first guide links, each of the first guide links having a first guide body that defines a pair of first guide apertures, each of the first guide links being disposed in proximity to an adjacent pair of the chain links such that one of the first guide apertures is aligned to one of the pair of chain link apertures in a first one of the adjacent pair of the chain links and a second one of the first guide apertures is aligned to one of the chain link apertures in the other one of the adjacent pair of the chain links;
• and
• a plurality of pivot pins received through the first guide apertures and the chain link apertures to thereby pivotally couple the chain links and the first guide links to one another;
• wherein at least one recessed anti-rotation feature is formed into the first guide body of each of the first guide links, each of the at least one recessed anti-rotation features being disposed proximate an associated one of the first guide apertures and receiving a male anti-rotation feature formed on an associated one of the pivot pins to thereby non-rotatably couple the associated one of the pivot pins a corresponding one of the first guide links.
