It's amazing what you might find. Sent from my iPad > On Oct 11, 2014, at 8:34 or PM, "bill.peyton" wrote: > > > I finished up replacing all three nose gear bushings, the 143 and 2-144's. When I took an more exact measurement, the 144's were both around .737 OD the 143 was .745 OD. I replaced them with the oversized .780 bushings obtained from Vans. The 144's were turned down to .7625. The 143 was turned to .7640. This left me with adequate clearance for the bushings. This also eliminated all of the play in the nose end of the nose gear, both horizontal and vertical. The AN hardware looked essentially new, so it was not replaced. The Vans P/N for the oversize VA-143 is Bush-ST 438X780X1.938 Oversize Bush VA-143. The 144 is posted above. > > The good news is after a couple of test flights and long taxis, I think I have eliminated 90% of the vibration I was seeing around 14kts. It was not side to side shimmy, but more of a hobby horse motion with the nose wheel. The excessive play must be exacerbating the resonance. It's not totally gone, I only felt it during the first taxi when the tire had a flat spot. After landing and taxing back it was essentially gone. I need to have a few more flights to pronounce it cured. > > If you have the RV-10 landing gear shudder and have exhausted all other avenues, this might be an additional check to make. > > -------- > Bill > WA0SYV > Aviation Partners, LLC > > > > > Read this topic online here: > > http://forums.matronics.com/viewtopic.php?p=431773#431773 > > > > > > > > > > ________________________________ Message 2 _____________________________________ Time: 10:05:40 PM PST US Subject: RV10-List: Re: #8!
