--> RotaxEngines-List message posted by: "Roger Lee" Hi Guys, If you qualify for the new extended 2000 TBO then you should replace these three items and make sure yo get it in your logbook. Only 2 are required, but it would be crazy not to do all three since they are all integrated. It takes about 10 minutes. Even if you don't qualify I would very highly recommend these part changes. It does make a difference that have have seen in all the aircraft so far. It will either steady the pressure and or raise it. They do a better job of controlling the oil pressure over the old ball bearing, spring and cap screw. For me personally this is a must do whether you have a 1990 or a 2009 Rotax 912. You should use all three new parts. cap screw 841-983 about $32- $35 spring 838-122 about $8 regulator cone 857-230 about $30- $33 Lockwood, CPS or Leading Edge should have them. -------- Roger Lee Tucson, Az.
