how do I reassemble my back up pad

Reply: How To Install The Back Up Pad

WJA

Hello 144351,

The best way to reassemble your back up pad is by looking at the parts diagram and observing where all the parts go.
Here is one model 259385. I think the most essential parts you will need will be the 877757 nut and the 877738 washer. If there are missing parts for the reassembly, look at the diagram of your correct model number and order them from us. And we'll get them to you ASAP.

Hope this helps,
-WJA

I am wondering how to remove the sanding head from a porter cable 7800 type 2 drywall sander
Hello,
I'm not real familiar with how these sanders are supposed to act so I will ask my concerns. I purchased it used and noticed a pretty good vibration, almost shaking, action when turned on and also when running down from being turned off it seems to make noise, although this could be just the drive shaft winding down. Any advise would be greatly appreciated!
Thanks in advance, Pat

Question: Bearings

How do I remove the bearings on the head of the Porter Cable sander so I can replace them? I have removed everything except the main screw.

I have a drywall sander, model 7800. I replaced the brushes on my sander. The time next I went to use it, after a few minutes, it stopped and started to smoke. Did I burn my motor up or where the brushes bad?
