When a new receiver was put under my 1HP oiled job the shop owner
commented it's last longer than either one of us. Noise is the biggest complaint on oilless.

Should I fix it or buy one of those new peak HP rated, aluminum, oilless compressors they sell now? I suspect that my old one, with a new tank, will still outlast the new ones. John |

Should I fix my air compressor?
My Sears Craftsman compressor is 30 years old and the tank has some pinholes
and is no longer safe. It has a real 220 volt honest 2HP motor with a belt driven 2 cylinder cast iron pump and a 20 gal tank. It's rated 8.3 cfm@ 40 psi and 7 cfm @ 90 psi.

For $150 to $200 you get half the CFM and a lot more noise. |

Ive had nothing but problems with the sears oil-less compressors, from stress cracking of the compressor mounting platform on top the tank, to the cooling fans repeatedly exploding to cracked and broken piston rods and damaged cylinder linings and the list just goes on and on........ Suggest avoid these at all costs--now you all been forwarned. -- SVL |

John Hi, By all means get a new tank. They don't build them like them old ones any more. You got a good motor and pump, why not? Tony |

I quickly realized after getting one on sale and sold it to a guy who was happy to get it off my hands. And then bought an old belt driven real deal. Happy now. Tony |

John I would be tempted to adapt a 40 pound LP gas tank for an air tank. The problem would be fitting a drain valve without weakening the tank. If you buy a new compressor, get a belt-driven oil-lubricated one with as slow-turning a pump as you can find, and discount all the CFM and HP ratings by 50%. I really wish someone would make a reasonably priced small 2-stage compressor, with an honest 3 HP motor and a 20 or 30 gallon tank. Bob |

stress cracking of the compressor mounting platform on top the tank, to the cooling fans repeatedly exploding to cracked and broken piston rods and damaged cylinder linings and the list just goes on and on........

If I'm shopping for a used compressor how do I tell if it is an oil-less one other than noting the noise (which I don't know how it would compare to oil compressor)? John Keith |

If I'm shopping for a used compressor how do I tell if it is an oil-less one other than noting the noise (which I don't know how it would compare to oil compressor)? Look for an oil filler and drain plugs or dipstick--this is all basically the same as lubricating the crank case and sealing the piston rings in your car engine. Usually, but not always, an oil-less units sales literature will tout "oil-less" as though its some kind of a BIG advantage, and so its more than likely gonna be mentioned in the items basic specifications. Now for a small unit and with hobby use, the oil-less units might have one possible advantage in that the air will have absolutely no oil in it.....maybe an advantage for some painting tasks like airbrush and the likes. -- SVL |

Splash lub compressors oughta have a drain plug to drain and change the oil.
Also some better ones have a sight glass so you can see the oil. -- Christopher A. Young Learn more about Jesus www.lds.org www.mormons.com "John Keith" wrote in message ...
