Compressor question
I have a Husky upright, not the great big one, but the one about chest high.
Two cyl compressor. I bled the tank today, and got water and a white milky oily fluid. Checked the dipstick, and it is low. I'll get some Husky oil today and fill. Do you think I damaged the compressor? Is the white oil in the tank normal? TIA Steve |

Yes it is normal, and no you probably didn't hurt the compressor unless the oil level had dropped below the oil slinger on the bottom of the connecting rod cap. Also, there's nothing special about compressor oil--the overwhelming majority will be perfectly happy with straight 30 wt non-detergent just like is used in lawnmowers etc, just don't use the wrong weight ( or a multi viscosity oil ) because the oil distribution system is based upon known oil properties as well as crankshaft speed. That white liquid is condensate mixed with a small amount of oil, the amount generated will depend on total compressor run time and outside humidity. Actual oil consumption is dependant solely upon run time ( discounting worn out piston rings ).....What this means is you might go several months without having to add oil as long as usage is light.... --but if all a sudden you spend an entire day constantly using an air die grinder or some such then you can almost bet that the oil needs topped off. By the way, if it has a cast iron pump unit then it is most likely the same one that's used on compressors offered by a very large number of different "manufacturers" http://tinyurl.com/3ekbmkr |

I've heard compressor-oil is low-ash and - well, something to do with compressors have a high "compression ratio" and can make a mess of ordinary engine oil - or even run as a diesel engine combusting the wrong crankcase oil. |

I dunno about that , but I've seen piston rings that were so carboned up that they couldn't seal properly . That was in a pump that as run way harder than the rated duty cycle though . -- Snag Learning keeps you young ! |

It could have been Mobil-1 off the shelf oil in a fancy-pants compressor-oil packaging, so that you would be coming back for more quarts at $29 a throw.

Compressor question
"Steve B" wrote in message .. . I have a Husky upright, not the great big one, but the one about chest high. Two cyl compressor. I bled the tank today, and got water and a white milky oily fluid. Checked the dipstick, and it is low. I'll get some Husky oil today and fill. Do you think I damaged the compressor? Is the white oil in the tank normal? TIA Steve Chapter two: I went to the borg and bought a pint or so of compressor oil for $250 US. Came home and found out that my compressor crankcase had just as much oil in it as it needed. It was not black, but not clear or white as I expected from the white oily stuff that came out of the bottom of the bleeder. I didn't open the bottle at all, so am not sure what color the new oil is. BUT, now I am curious as to what the white oil was in the tank with the water? Anti rust stuff? The compressor works fine, pressures up fast. So, back to trying to identify the white oily liquid. The compressor is just as it should be oil wise in the crankcase. One last question: When checking oil, is it proper to stick the stick the 3/4" or so down into the casting, or check the level by just putting it in until the stick hits the casting? The bottom of the dipstick has a bell shaped plastic area. You then have to push it into the casting to get it all the way in. I know in cars and lots of machinery,you stick the oil stick in all the way, but have wondered about those others with screw in dipsticks, or these push in types. Which way is correct?

Compressor question
While we're on compressors... Anybody have any info on thie compressor? http://home.tallships.ca/mspencer/temp/atlas-copco.html Dunno how old it is. Seems to work well except for an annoying problem described on the web page above. Atlas-Copco seems to have no record of ever having made/sold it. BTW,when it's been running, the oil in the crankcase is milky, I assume from getting water homogenized with the oil. Using 30 wt. non-detergent motor oil. Should I be using something else? It's rated for 400+ PSI but I only run my tank up to 150 PSI so the compressor is presumably more or less loafing. -- Mike Spencer Nova Scotia, Canada |

Steve Suggestion / question - is the white at-least partly oily stuff a suspension of oil-in-water (like milk itself) or vice-versa (water in oil)? A rough experiment would be to heat up some of it - water would steam off and you'd be left with clear oil (OK - sorry - some of us have this problem that we always try to jump to a way of finding-out these things... :-) ) Rich S |

[3rd stage over-pressure valve pops repeatedly] I would guess non-compressibles in the high pressure section are being vented off... Duh. Makes perfect sense. The right amount of oil or oil/water emulsion would do it, wouldn't it? It's an old beast, probably heavily used for many years. And oil mist does blow out when the valve pops. But it never occurred to me that the amount of oil reaching that stage could make that difference. --definately beats the alternative. Yeah. Oh, yeah. Thanks, -- Mike Spencer Nova Scotia, Canada |
