Hi there all,
Oil pressure on the 912S fitted on my MCR 4S) is ever low, under 2 bars and
just over the red line... Is there a way to trim it?
BTW it is not much more on the 912S on my Europa, just above 3 bars.
Cheers,
Max Cointe

May be time to replace the oil pressure sending unit. I still hard mount
mine. They do not last long. One of these days I will remote mount and see
if I can get more hours out of it.

Max I had the same thing, turned out to be air in the system.

29 psi to 43 psi is within the guidelines, but anything below 40 psi seems a bit
low to be real. The number one cause for low readings is the sending unit. They
cost about $35.

The second cause is air in the oil sending line.
The other item that should be done is install the new oil pressure regulator cone,
spring and cap screw. It only takes about 5 min. and cost is around $75.
The old ball bearing can and will cause lower readings for some.
Never add shims unless you put an inline mechanical gauge in the oil line to test
the real pressure or like the majority of people will actually over pressure
the system because they never checked it and the readings were lying to them.
Volume is more important than pressure.

The first question I would ask myself is weather there is a real problem of
low oil pressure or is it a simply an indication problem. The way to verify
it is to (temporary) plumb a mechanical oil gauge using a T fitting and to
compare the readings of the Rotax provided sensor with the mechanical one.
Depending on the outcome of this test will be the diagnostic/corrections
actions
