Hey - I've been posting about a problem I've been having in the RV-7 forum about a "clunk" I have been hearing when landing. Since there are many 6,8,9 and 10's with nose wheels, I thought I'd post my question here.
One item that was suggested to check was the breakout force and to grease the nose wheel.
I have greased the nose wheel pivot joint, and measured the break out force in the low to mid 20lb range. But now that I think about it, the nose wheel has seemed to get a bit "stickier" over the past few months. When I use the tow bar to turn the wheel, it doesn't turn smoothly, it seems to want to move in short "hops."
I wonder if the "clunk" I am feeling is the same "hopping" friction when the wheel straightens out on landing.
I know that there needs to be some resistance (i.e. breakout force), but how smoothly should the nose wheel turn side to side?
Thanks,
Jason
