Selecting Replacement Needle Bearings - Precision Ground vs Non for Wrist Pin?

[Burgerkong]

Obviously precision ground costs more (in this case, 2.5 times) but at the same time, I cannot find a replacement wrist pin (50's era Kellogg 331 compressor) for a reasonable price so I plan on reusing the old wrist pin. It has been running on a damaged full complement needle bearing for a while (a bit of radial play - ie, conrod wiggles) - the original spec called for a GB1616OH which is a precision ground 1616 bearing. Now my wrist pin is far from mint (bit of pitting and a tiny bit of wear), so I was thinking the precision ground component is kind of lost when installed.

Thoughts?

Wrist pin will tear up new bearing if is as bad as it sounds. Get a new pin and vearing

Fack, I was hoping that wouldn't be the case, but deep down I already knew. Now comes the question of precision ground vs non. Say cost is an issue, can I get by with a regular precision bearing on a compressor?
