I know for sure

That my Denon DP-62L bearing job is the one on the left.

I know it because I spoke to Jim about the problem he had with replacing the thrust pad at the bottom of the motor. He sent me photos when he was doing my bearing, showing me how he went about replacing the thrust pad.

It required machining the bottom of the motor open so the new thrust pad could be properly mounted. IIRC that was necessary due to the new thrust pad's increased height (or something like that).

He also had to machine the end of the spindle so the ball could ride there properly. My original main bearing was worn with the end of the spindle out of shape, the thrust pad had a dimple worn into its surface and the walls of the bearing needed machining.

The symptom with my main bearing was a thumping sound. This was caused by the combination of the dimple in the thrust pad plus the worn end of the spindle. The ball would ride up and down slightly due to the uneven wear and cause the spindle to rise and fall slightly.

When the spindle fell back into place it made the thump sound. This rise and fall also contributed to the wear on the bearing walls.
