Pioneer From Model PL-12D Original Center Shaft Assembly - W71-004-D

The Pioneer From Model PL-12D Original Center Shaft Assembly (Part No. W71-004-D) is the essential central mechanical component of the vintage Pioneer PL-12D belt-drive stereo turntable. This part is the spindle or main bearing assembly upon which the turntable's platter rests and rotates. Its function is to provide the low-friction, precise pivot point that ensures the platter spins smoothly and consistently, which is crucial for accurate playback. The entire assembly (the shaft and its housing/bearing well) often requires careful oiling and maintenance to prevent the "gumming up" that can cause speed issues in these classic turntables.
