It states the correct number in the Vans' plans. I also agree with Kelly, I haven't had any nose wheel shimmy with my IO-540. I'm thinking engine preference is not the issue. You might stick a camera on your tie-down mounts and make sure its the nose and not the mains. If it is the nose it is either the belleville washers, the axle or the play in the bushings on the nose landing gear mount/engine mount. I had to make new bushings that had better tolerance than vans' bushings. -------- 40936 RV-10 SB N801VR Flying 780 Hours SuperSTOL 60 hours Read this topic online here: http://forums.matronics.com/viewtopic.php?p=473195#473195 ________________________________ Message 2 _____________________________________ Time: 07:47:42 PM PST US Subject: Re: RV10-List: Re: Nose gear shimmy From: Tim Olson On the RV-14 (Same nose gear as the -10) I could swear that the original plans had it bumped up to 35lbs of breakout. I just checked the plans now though and they list 26lbs. I would say stay on the high side of Sean's numbers, not the low. By the time it gets down to 20 it's going to be pretty loose. And, they wear in pretty quick, so after your first flight, check it before 50 hours, and then check it again at maybe 100. After that it should be more stable.
