A connector pin assembly for use in removably retaining a ground engaging wear member on an associated support structure portion having a connector opening therein, the connector pin assembly comprising: a hollow body longitudinally extending along an axis and being removably receivable in the connector opening, said hollow body having opposite end surfaces through which pin openings axially extend; a connector pin member having: a fixed length, a longitudinally central portion coaxially and rotatably received in said hollow body, opposite end portions exterior to said hollow body, having abutment surfaces captively retaining said hollow body on said longitudinally central connector pin member portion, and having axially facing outer end surfaces, and locking/adjustment projections extending outwardly from portions of said outer end surfaces, each of said projections having an outer side surface with an eccentric curvature with respect to said axis; and cooperating detent structures (56, 98) on said hollow body and said longitudinally central portion of said connector pin member for releasably retaining said connector pin member in selectively variable rotational orientations relative to said hollow body, characterized by; said hollow body having a tubular configuration and is formed from two releasably interconnected lateral portions; and said opposite end portions being laterally larger than said central portion. a hollow body longitudinally extending along an axis and being removably receivable in the connector opening, said hollow body having opposite end surfaces through which pin openings axially extend; a connector pin member having: a fixed length, a longitudinally central portion coaxially and rotatably received in said hollow body, opposite end portions exterior to said hollow body, having abutment surfaces captively retaining said hollow body on said longitudinally central connector pin member portion, and having axially facing outer end surfaces, and locking/adjustment projections extending outwardly from portions of said outer end surfaces, each of said projections having an outer side surface with an eccentric curvature with respect to said axis; and a fixed length, a longitudinally central portion coaxially and rotatably received in said hollow body, opposite end portions exterior to said hollow body, having abutment surfaces captively retaining said hollow body on said longitudinally central connector pin member portion, and having axially facing outer end surfaces, and locking/adjustment projections extending outwardly from portions of said outer end surfaces, each of said projections having an outer side surface with an eccentric curvature with respect to said axis; and cooperating detent structures (56, 98) on said hollow body and said longitudinally central portion of said connector pin member for releasably retaining said connector pin member in selectively variable rotational orientations relative to said hollow body, characterized by; said hollow body having a tubular configuration and is formed from two releasably interconnected lateral portions; and said opposite end portions being laterally larger than said central portion.
