(PLEASE READ) (Matt Dralle) ________________________________ Message 1 _____________________________________ Time: 07:28:04 AM PST US From: Ian Brown Subject: RV-List: RV-6A shaky nose wheel Bob Collins asks a good question. It's always confused me too. How do we know when a wheel is free enough? I've packed loads of grease after cleaning the bearings, then tightened until there's just no free lateral play, but at that point the wheels don't really turn freely. In fact they stop the minute you stop turning them. I was surprised when the AntiSplat nose wheel job came back and I mounted it. It turns as freely as a bicycle wheel! (I'm not connected with them in any way, by the way, just a fan). I guess for the standard conical bearings, for the load bearing points, looser doesn't really change much in terms of pressures and weights on bearing surfaces. Are there any experts out there - how much grease should these bearings get and how tight should they be? "The "turn freely" part of this has always confused me. The instructions are vague on this (tighten to prevent bearing from turning with the wheel) and seemingly encouraging it to be tight enough that if you try to spin the wheel by hand, it won't move that much. What do other folks do on this point?" ________________________________ Message 2 _____________________________________ Time: 08:00:37 AM PST US Subject: Re: RV-List: RV-6A shaky nose wheel From: Dan Bergeron Good Morning Here's another two cents FWIW - I have an RV-7A my wife and I built over 6.5 years in our one-car garage - I too have puzzled over nose wheel axle tightening - I tighten carefully just to the point where there is no lateral movement in the wheel and no further - at that point the wheel still turns freely (remember that's a 4" wheel so there isn't going to be a lot of spinning free as with a bicycle wheel) - I clean the bearings thoroughly with a solvent and grease them using a bearing greaser available in most auto parts stores - wipe most of the excess grease from the outside - put a small amount of grease around the race and put it back together - haven't had a problem in 458 hours - Dan Bergeron RV-7A N307TB 458 hours since first flight Aug 2009 On Thu, Apr 17, 2014 at 10:27 AM, Ian Brown wrote: > > Bob Collins asks a good question.
