Reply: How To Install The Back Up Pad
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,
Question: Porter Cable 7800 Drywall Sander
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
