Many years ago I had one similar to Ed's. Besides running at 3450, it was extremely noisy. It also didn't have a finned output tube. Then the direct drive started acting up. Opened it up and found the bolt that holds the taper was loose.
I also had a Home Depot oil-less compressor. Not as noisy but not as reliable either. The bearing got hot and worked its way partially out and was grinding the flywheel/crank on the housing. Eventually I put the oil compressor pump on that tank and tossed the original one (my version of tossing usually means it's on a shelf somewhere). After I got tired of the noise I bought a new (to me) pump and motor off Craigslist and replaced it.
One of the guys in the local club gave me his old tank and 3HP motor and last summer I put the $139 Harbor Freight pump on it. Nice and quiet now!
