I haven't taken it apart to see exactly what the problem is, but its

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.


I finally got the new pump installed. Had to make a mounting plate,
then drill and tap for the new pump, then chase down the fittings, and
finally take the check valve out 4 times to try and repair it. Finally
I did the stupid easy o-ring repair. I know it won't last, but it
should last until I get a new check valve atleast. The plunger on the
check valve looks like PEEK. Kind of overkill for only 155 PSI.

Do an autopsy of the old pump and see why the oil issue was not
noticed
