Rebuilding a 333 PC RO Sander

[Dan]

When it finally goes up in smoke what all do I need to replace to breathe life back into my favorite sander? It still operates but very, very roughly.

Try replacing the bearings, the random orbit belt, the rubber spacers inside the housing that hold the field firmly in place and check the aluminum housing that holds the bottom bearing. This sometimes gets worn inside allowing for a sloppy fit for the bearing. I hope this helps.
