Folks
I am looking for info on how to remove and replace one of my ball bearings =
that supports the elevator on the tail. Anybody with experience of this? On=
e of my bearings has more play in it than I would like. Also looking for a =
source;  I expect they are Timken
Thanks


Tom,
You didn't specify which model of Lancair you have...but your description o=
f "ball bearings" implies this is for a 4-seater (all--not sure?). If so, t=
hese bearings are pressed into an aluminum hinge bracket. If the bearing ha=
s turned in the bracket, you'll need to replace the bracket as well as the =
hinge, as the aluminum wears much faster than the hardened steel bearing. I=
f the bearing itself is the worn part, it can be pressed out using a vise o=
r (preferably) an arbor press made for the purpose, and the new bearing pre=
ssed in. It's usually a good idea to put a small amount of LockTite around =
the mating surfaces, and to stake the edges of the retainer to hold it in p=
lace. Lateral positioning of the bearing is important. You need to position=
 the new bearing in the same position in the bracket as the old, or the hin=
ge will bind when you re-install the elevator. Lancair can provide both the=
 bracket/bearing as an assembly if desired. I'd recommend this to get the r=
ight part and to be sure you fix the problem. Not sure how/where else to bu=
y these spherical bearings, as they are know, separately.
