LML,
My nose strut, an old Esco u= nit, released a bunch of oil during the past year while I have been working= on the plane.  So I removed the strut to send off to Lancair for a re= build.  I would try it myself, but from what I have read the seals are= not available so I must send it to Lancair.
 
The Problem:
So, here is a video of what I found when I removed the strut.
 
With the nose gear installed completely, no play was noticeable in any of the parts.  But as you can see in the video, the over cen= ter link has tons of play in the center pivot bolt hole.  The nose str= ut itself does not allow any lateral play so I am a bit confused as to = ;how it elongated the hole.
 
Solution?:
The easy fix would be $240 worth of Lancair parts, but will it happen = again?
Insert a bushing?
I don't think there is enough material to drill the hole for the next = size bolt, although that would be a beautiful fix...
 
My only other idea is that there is an alignment mis-match between the top of the nose gear link pivot,= and the pivot of the nose gear itself.  During the retract it pu= ts things in a bind causing premature wear. Thus if I remove all of th= e "play" in the link itself, will it retract without binding?
 
Or, is this totally normal?
 
Just FYI, I didn't build this airplane and it has about 700 airframe h= ours.
