porter cable 333 oscilating sander

[riverainstruments]

the sander stopped oscilating. I noticed the plate would just spin (as it burned the finish on one of my instruments ). I opened the sander and noticed the belt that gets the oscilating action going was gone. I purchased one and replaced it on the unit.

When I turn the unit on, the sander vibrates but it does not spin or oscilate anymore.

What could be the reason? I've checked and rechecked re assembly and its according to diagram. Any ideas?

Hey riverrainstuments,
Most likely it is the bearing # 20 part # 865119 that is locked up..it is located in the pad support..also check your fixed pulley for wear.#37b .. you can sometimes loosen the screw and then rotate the support for a simple fix..but it sounds like that bearing is the culprit..parts avail at ereplacementparts.com
hope this helps
