Hey Rob, My 3300 is #756, currently with about 118 hours TT. I replaced the OP sensor that came on the engine early on, at about 30 hours or so, because it was showing OP fluctuations, or "flicking" as Jabiru calls it. Andy Silvester recommended that it be changed to a VDO sensor. Since installing the VDO OP sensor the "flicking" has gone away. Don't expect Jabiru to honor their warranty your OP sensor, though. Their stated warranty seems to be worth about as much as the paper it's printed on, if it's worth that much. They exhibit very "Rotaxian" behavior when it comes to warranty issues, IMHO.......

I quote the parts that are of interest: ....It only takes a slight change in oil temperature to cause a significant change in pressure....(talks about using washers under relief valve spring to get some added pressure) ....Before you do anything else, a check of the drop across the engine is warranted. First warm up the engine to operating temperature. Connect a pressure gauge to any output fitting on the back of the oil pump or some place close to the pump --.. can also be a fitting in the oil galley..... Then attach a (another) pressure gauge to the left front galley on the case (continues about how but may not be applicable to Jabiru engine) ..... Check the oil pressure on both gauges with the oil hot and record reading at idle and in cruise configeration. The drop across the engine should be around 8 to 15 PSI. If the drop is around 20 PSI or more, then internal clearances -- bearings, cam followers, etc are affecting the pressure. If the drop is fine, then your loss in pressure is caused by a relief valve that is relieving oil pressure too much, or work needs to be done to the baffling and oil cooler to lower the temperature a bit. Continues but not relevant.

I think you shared those thoughts before and a lengthy thread followed. USAJabiru instantly replaced two OP senders on airplanes we know about. No warrantee hassles at all. If memory serves, you were offered a replacement also...through the dealer; which is how warrantees are handled. If I have you confused with someone else, please let me apologize in advance.

No hassles or problems here getting any items taken care of. I beleive maybe you are going about your claim in the wrong fashion.

During the first 50 hours or so the oil pressure sender was replaces twice under warranty by my dealer - USA Jabiru in Tennessee. They are absolutely great people. The symptoms were oil pressure fluctuations as was previously mentioned and the VDO sender has been problem free. If any of you have not been to their engine seminar, I highly recommend it. By the way, during the 366 hours the engine has been outstanding, requiring only routine maintenance. I change oil and filter every 25 to 30 hours, re-torque the heads and adjust the valves on schedule, and change plugs every 100 hours.

During flight occasionally I found a slight low frequency vibration. Grounded during extended bad weather I spent 3 days at home static balancing the prop/spinner/backing plate combo. Very tedious but I made it perfect. Soon after in flight and when decelerating and turning left I got massive scary low frequency vibration enough to shake the cowl and it did not disappear as I cut throttle. I got the setup dynamic balanced a 3/4hr job. From the first weight attachment the engine was totally different and silky smooth. It took a =BC=94bolt =BE=94 long with nut and washer mounted in the backing plate 4=94 from centre and NO WAY is the prop combination now in static balance. The dynamic balance has cured an engine imbalance. I would recommend it to all J3300 operators because I think this kind of engine imbalance contributes to the problem of flywheel bolts breaking. (My engine was updated and factory rebuilt to zero hours last year) Peter H _____ From: owner-jabiruengine-list-server@matronics.com [mailto:owner-jabiruengine-list-server@matronics.com] On Behalf Of N1BZRich@aol.com Sent: Saturday, 29 September 2007 1:34 AM Subject: Re: JabiruEngine-List: 3300 OP sensor All, My 3300 engine is serial # 843 and has 366 hours in the last 21 months in my highly modified Esqual LS (Lightning Stuff).
