Porter Cable 903373 Belt - Random Orbit

Easy to install - works well.

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.

Just what I needed. Great quality.

Fits well my 333 grinder and works well. Thank you!

It fit and now I can sand forever. Fixed my sander.

This is simple -- Remove the sanding pad (three screws), take off the old belt put the new one on. Screw the pad back on and start sanding.

Exact fit

It works as it should

This is a great repair part for your Porter Cable palm sander.

Perfect
