Random Orbital / Dual Action sander repair/cleaning?


I have a Porter Cable 7346 Random Orbital Sander: looks like this:



I used it to make fast work of some drywall repair - which was stupid of me. It seems as though the dust has accumulated in parts that should not accumulate dust. The sander started slowing down, and making a grinding/screeching noise. If I take it off the surface and let it spin, it seems to return to normal, but as soon as you put pressure on the sanding pad, it loses power and starts screeching again.

Is it toast? Are there any parts I can take apart and clean/rebuild? I've only had it about 2 years, but I bought it manufacturer refurb, so I won't have a warranty.

Thanks

Gypsum(drywall dust) destroys lubricates. That's why drywall guns are sealed. I'd take the gearbox apart and clean out the old contaminated grease. Regrease with a high quality grease such as valvoline syn power.

bearings are shot.. that can be fixed just take it to the closest dewalt factory service center as black and decker owns both dewalt and pc.. you can go to a different tool repair shop but it will take longer to get back as they will have to special order teh parts

Any wild guess as to what that might cost? I looked up the nearest service center - 45 minute drive. So, 3 hours there-and-back twice (drop off and pick up) for about $40 in gas, plus the cost of repair. Might be a net benefit to just bite the bullet and buy another refurb. for $110 - charged to "I knew better, but didn't listen to myself."

Any reason why you chose that style and not a palm style? A whole lot less expencive and easyer to use.

This style doubles as a polisher for automotive uses too.

Thanks for that link!
