I'm not familiar with the expression "cracked it", I gather you mean got it right, but when you say it in reference to a bearing, it could be misinterpreted. I can see the newbies running to their arms now, getting no play and lamenting "Oh no, I've cracked a bearing."
I'm kinda teasing here, I've been up all night, but you get my point.
I did of course mean 'cracked the problem' -
"but you get my point." If you comb your hair right it won't show anyway ;-)
All kidding aside, tonearm bearings aren't all that fragile or prone to damage or wear, and loose bearings on Vintage arms are quite often easily adjusted to remove the play.
Loose bearings are detected by gently pushing the arm wand back and forth in either axis and feeling for slop, or the inverse where the
bearings are too snug abnd restrict the arms free movement, obviously certain arm types like SME 3009's Unipivots etc. preclude
that sort of test due to their design.
I've bought quite a few Vintage tonearms and the vast majority have
nice bearings despite being 20 to 40 years old with multiple owners.Avoid crazy stuff like using the tonearm as a carrying handle, and when adjusting azimuth or removing the headshell etc. grasp the the rear of arm wand firmly to avoid torquing or tweaking the bearings.
Some brand new arms may need a few hours of use for the bearings to settle in just like anything else mechanical in nature.
