How to Replace the Clutch Drive Belt on a Porter Cable Sander
Drive belt broken? It's time to face the fix. Whether you are a master carpenter or a seasonal sander, eReplacementParts.com provides the parts, procedures and facts you need to fearlessly fix what fails you.
The clutch belt is the clutch mechanism that stops the sanding pad from spinning when you remove the sander from the work piece. When the clutch belt is broken, the pad will spin almost out of control. With the pad spinning so fast, it becomes difficult (if not impossible) to engage the work piece without damaging (or gouging) the wood.
This article provides step-by-step instructions for removing and installing the clutch belt on a Porter Cable Quicksand 333 series sander.
