Porter Cable 903373 Belt - Random Orbit

worked well, sander now works properly

This is a very stiff belt. Instead of transfering about half or so of the motor spin into random orbit action, it just sort of locks up and the sander spins up like a non-random orbit sander. If you turn it on and wait more than a couple seconds before appl7ing it to the board, it sands fast, but not smoothly. Not good.

good

I was ready to throw my old sander away until I found this part on Amazon (where else). Very easy to install with nothing more than a screw driver. Remove 3 screws, remove cover, install new belt.

This product arrived quickly and fit my Porter Cable 333 random orbital sander perfectly.

Let me add my 5 star review to others. Worked a treat. Of course the old belt broke on the first piece of my project but a square sander did the trick. Not as well but it worked. Well pleased to get my go-to sander back.

This belt is a factory replacement and seems to be made of better material than the one that came with it.

It fixed it

Works great. Get a couple of these to have as spares.

This fit like they said and my sander is back at work
