Porter Cable 333 problems

[robthom]

I have a 15 year old PC 333random orbital sander. recently the cover (I guess that is what the skirt that covers the pad at the bottom is called) at the bottom has begun rotating when the sander is on, winding the power cord about the sander. The belt appears to be intact, but I wonder if it is too slack. I replaced it once about six years ago.

Should I replace the belt? Or is it another problem?

Hey Rob,
You may have a bearing problem..if the pad support bearing locks up it will cause a lot of problems..part# 865119 also the fixed pulley probably has some wear and will need to be rotated or replaced #878884
hope this helps..?
