I was going crazy trying to figure this out also, the thing that I did that worked pretty well involved grabbing the "loose" ends of the springs with two pairs of small vise grips and holding the spring in exactly the right position to either remove or install the pin that goes across and holds the clamp on. It's really tricky and although I did it myself it would be helpful to have another person there to hold things, it's a bit surgical-like. You will need two pairs of small or needle-nose vise grips, don't even attempt to do it without those, you can't hold the tiny spring wire well enough with regular pliers.

I'd tell you but I'd have to charge $12.99. for the info. I went to a free blog instead.

I inherited this sander (Porter-Cable model 330) and the owners manual did not come with it. I am stumped as to how and get the side levers to lift so that i can change the sandpaper (non-stick paper)....

there is a wrench supplied with the tool that you need to insert in the slot on the clamp and push the wrench towards the tool to open the clamp. Now if you follow closely I can direct you to a manual and parts list. Go to "" and scroll down to the bottom and you will find a porter cable link, click on that and then when you get to the next page click on tools. Scroll down till you find sanders and click on that. Next find finishing sanders and you will find your model sander click on the description and it will again redirect you to another page where you can find the manual. The whole manual is 44 pages long but that includes other languages. The page that you specifically need is page 10. If you have a problem let me know and I will try and help. This is the first time that I have had to take this route to find a manual on their site.

Extreme Vibration in my Porter Cable (Rockwell) 330 Sander

I also have had this problem and I found that if I hold the unit tightly and squeeze the plastic housing the RPM's will stabilize as the unit warms up. Best fix is to replace the rubber isolators that prevent vibrations from the motor from reaching the plastic housing. The isolators have become hard through age or very cold temperatures.
I read somewhere that keeping the sander stored in a warm room can also help because when the rubber is very cold it becomes hard.

How do you replace bearings on a porter cable 505 sander?

First I would go to and in the middle of the site towards the bottom type in your model number. I found breakdown on page 8 unless it comes up faster. You will need a bearing puller or something similar because they are pressed on. It is really not that hard with the proper tools. Let me know and if I have answered your question would you please rate this response accordingly and Thank you.

Excess vibration

Remove the 4 sander plate screws being carefull not to strip them. Look at the plastic ******** extentions attached/flooting to the houseing and look for broken or bent arms on them ,replace with new ones, this should solve your problem.
