The number one cause for low readings is the sending unit. They cost about $35. Single pole sender: http://www.egauges.com/ProductDetails.asp?ProductCode=360-004 Double pole sender: http://www.egauges.com/ProductDetails.asp?ProductCode=360-430 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. -------- Roger Lee Tucson, Az. Light Sport Repairman - Maintenance Rated Rotax Repair Center - Heavy Maint.

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 Nati RANS S6S 912ULS, Illinois On Tue, May 20, 2014 at 8:27 AM, William Daniell < wdaniell.longport@gmail.com> wrote: > Max I had the same thing, turned out to be air in the system. > Will > > William Daniell > LONGPORT > +57 310 295 0744 > > > On Tue, May 20, 2014 at 8:15 AM, John Hauck wrote: > >> jhauck@elmore.rr.com> >> >> May be time to replace the oil pressure sending unit.
