LML,=0AMy nose strut, an old Esco unit, released a bunch of oil during the =
past year while I have been working on the plane.=A0 So I removed the strut=
 to send off to Lancair for a rebuild.=A0 I would try it myself, but from w=
hat I have read the seals are not available so I must send it to Lancair.=
=0A=A0=0AThe Problem:=0ASo, here is a video of=A0what I found when I remove=
d the strut.=0Ahttp://www.n54sg.com/video/nose_gear.mp4=0A=A0=0AWith the no=
se gear installed completely, no play was noticeable in any of the parts.=
=A0 But as you can see in the video, the over center link has tons of play =
in the center pivot bolt hole.=A0 The nose strut itself does not allow any =
lateral play so I am a bit confused as to=A0how it elongated the hole.=0A=
=A0=0ASolution?:=0AThe easy fix would be $240 worth of Lancair parts, but w=
ill it happen again?=0AInsert a bushing?=0AI don't think there is enough ma=
terial to drill the hole for the next size bolt, although that would be a b=
eautiful fix...=0A=A0=0AMy only other idea is that there is an alignment mi=
s-match between the top of the nose gear link pivot, and the pivot of the n=
ose gear itself.=A0 During the retract it=A0puts things in a bind causing p=
remature wear.=A0Thus if I remove all of the "play" in the link itself, wil=
l it retract without binding?=0A=A0=0AOr, is this totally normal?=0A=A0=0AJ=
ust FYI, I didn't build this airplane and it has about 700 airframe hours.=
