Yanmar generator oil pressure - Scott Forman - 06-03-2007 03:02
I took a day-trip yesterday that had the generator running for about 16
hours straight. On my way home, the oil pressure gauge for the gen
engine began reading very high, almost pegged to the right. While I
know what low oil press can do to an engine, I have never really heard
any talk of whether high oil pressure is a big problem. Is it? If it
is a true problem and not an instrument issue, what is the likely
cause? It may well be the gauge, when I turned the gen off, the press
gauge only retreated about half way. I checked the oil before leaving
yesterday and it was fine. Have not done any investigating yet this
morning. The gen seemed to be running perfectly otherwise, the water
temp was fine and there were no odd sounds, smells, etc.
Ideas?

Scott I would replace the gage if it is not zeroing out
while the engine is shut down I would have to take a hard look at the gage.

Might be preaching to the choir here but I would change out the complete
system.....sending unit and guage.

Good advice,
Sounds like the gage, then the sensor must match up,
Test and replace both.
A good gage test guide is on the Teleflex web site.
