Rotax 912 and oil pressure differences
in General Tech Discussion
10 years ago
Hi.
I have following problem.
When I't turn engine on I can read 4BAR oil pressure (cold). When engine is warmed up (oil about 80-90*C) pressure drops to 2,7-3BAR on 2000rpm. When I add to 4500RPM pressure drop's to about 2,5BAR, when I move back to idle it's raising back to 2,9-3,5BAR.
It is normal? My friend has 912ULS and he have always between 3,5-4BAR.
My engine is 1995 and 850hrs and probably I have old style oil pressure regulator. It can be caused by this?
I don't see fluctuations (flydat) but sometimes when I back from 4500 to 17000rpm there are a little bit of fluctuation in idle for a few seconds.
