This could be a gauge issue, but the swings are still close enough not to be. Here are the part numbers for the new Rotax parts. It takes 5 minutes to install. This has stabilized many an oil pressure as that is what it was originally designed for and it may raise your pressure 5 psi or so. I have installed these in at least 20 aircraft. These parts cost about $75 < These parts caused my oil pressure to fluctuate all over the place from what was previously a pretty steady indication so I went back to the old original ball /spring which works fine. I guess the old adage of "if it ain't broke ,don't fix it " applies in my case But then I also have a weird 912 Ul of the early 90's vintage . It does lots of things different from anyone else's 912 Dick Maddux Milton,Fl ________________________________ Message 2 _____________________________________ Time: 07:56:37 PM PST US Subject: RotaxEngines-List: Re: unsteady oil pressure From: "Roger Lee" I put these parts in a 2006 Rotax 912ULS today and the plane has a nice steady 55 psi oil pressure, not to mention another 500 hrs onto the TBO. Rotax parts: cap screw 841-983, Spring 838-122, and oil pressure regulator cone 857-230 -------- Roger Lee Tucson, Az.
