I haven't taken it apart to see exactly what the problem is, but its
four years old. A full year out of warranty.
An hour or so ago it started making an awful racket. It sounded
suspiciously like it threw a rod. I shut it down along with all the
machines dependent on it.
Diagnostic step one. I looked at the oil sight glass, and it showed
just below center. Figuring to see how much of its guts poured out I
cut the top off a soda can to catch the oil and pulled the plug.
Nothing came out.
As one of our members would say... Blink!!! Blink!!!
I looked at the sight glass again. The oil level looked the same. I
stuck an air nozzle in the drain hole (turned off the compressor, but
left the valve open) and blew thinking maybe it was plugged. A very
little oil came out and several chunks of metal.
I check the sight glass almost every day when I start up the air for the
shop. It never changed. I wonder how long it was running with
virtually no oil.
Well, I'm off to buy a new pump for it. I can't run without air.
What brand was it?
Ive learned over many years repairing machinery...NEVER trust the
sight glass if its the flush disk type. They can built up a layer of
crap behind the glass..which plugs off the lower hole..leaving the
sight glass filled with oil, like a deer on the wall...nothing behind
it.
Thanks for this thread and comments - gonna double check my sight glass
today by dip test! C+
I try to remember to flush out the crank case of air compressors at
least every 5 or so years. Drain, fill with diesel or kerosene, let
it run for 5 or so seconds, drain again and then refill with proper
compressor oil. Remember...NON detergent oils only..if you want to go
cheap and fill it up with a quality 40 weight motor oil and not get
raped by buying way overpriced "Compressor Oil"
Mobie 1 synthetic works pretty well also. But its pricey for a
couple quarts.
