Installed this retainer and the hand wheel no longer wobbles—the machining is precise enough that everything lines up perfectly. Took about ten minutes to swap out, and now the drive mechanism feels solid with zero play.

The hand wheel now sits perfectly solid on the column, no more wobble when I crank it for fine depth adjustments. The retainer's machined fit was exact, and it took only a few minutes to swap out the old part.
