Claim:
A section of chain for conveying product along a conveying system, said section of chain comprising: at least two chain links having apertures through opposite ends thereof; and a pin connecting said chain links together via insertion of said pin through said apertures in said chain links, said pin comprising opposite end portions and a shaft portion extending between said opposite end portions, said shaft portion defining at least one wear surface that movably engages at least one of said chain links as said chain travels along a conveying path, said pin being selectively adjustable between at least three positions relative to said chain links to adjust said at least one wear surface of said shaft portion relative to said one of said chain links, said pin being generally non-rotatable relative to another of said chain links when in each of said at least three positions; at least one of said end portions or said pin defining at least three engaging portions for selectively engaging corresponding wall portions of said aperture of said other of said chain links, whereby said pin is generally non-rotatable relative to said other of said chain links when in each of said at least three positions; and said at least one wear surface comprising at least three wear surfaces that correspond to respective ones of said at least three engaging portions of said at least one of said end portions of said pin, said pin being selectably rotatable to adjust said wear surfaces relative to said one of said chain links to provide selective engagement of one of said wear surfaces with said one of said chain links, wherein said shaft portion is rotationally non-symmetrical and said at least three wear surfaces have different radii relative to one another.
