It is extremely unusual for a connecting rod to break and not damage the crank throw, rod journal, or "pin" as you want to call it. I am puzzled why you are concerned about this rather than the OP.

Most blown rods I have seen have gone thru the crankcase and damaged the crank. High end motorcycles mostly.
These engines, running normally at 3,600 would not be over revved (usually).
Yes, I am interested in WHY / what failed to cause the rod to blow. Anyone can swap parts. Why it failed-lack of oil, clogged oil lines-not cleared/fixed (if the issue) would cause the rod to blow AGAIN.
Whether the Op cares or not, frankly is not my business. In doing my repairs for a failed part, I want to know why so it's repaired and does not come back blown up again-something that I should NOT have missed..
Likely due to over revving (not likely in this case), or a failure elsewhere(IE, had a large Yamaha PW that the pressure release failed and the rod came loose with major knocking / damage)
IE: An Echo CS355T Chain saw, "blown" (locked up) that I went into (out of curiosity) AND was able to repair.
A crankshaft "stuffer" failed (came apart) and locked up the engine. No internal damage to the engine, removed the other one and re-assembled. It's now back into service for my customer with NO NOTICABLE difference in performance. Saved a $350 machine from the scrap pile..
Video of it re-assembled, being tested..
