 |
|
I've just installed my elevator after replacing the bearing material and clevis pins. It will fall through to the down stop but not very fast. Funny part I can lube it and move it up and down and it looses up and feels normal but let it sit a day or so and it gets stiff again. anyone else experienced this ?

Yes, and in my case it was the (factory) welding of the hinge
segments to the leading edge of the elevator, or the same to the
trailing edge of the horizontal stab. Take the elevator off the plane
and try to sight through the hinge segments from one end of the
elevator to the other...I'll bet you won't be able to on one part or
the other. The fix is to "adjust" the individual parts so that you
CAN sight from one end to the other, either by bending or by whatever
means available. Just like any hinge, all the segments or elements
must align, or the hinge will be stiff. How about sighting down the
hort. stab. hinge segments to see if it maybe the support rods are
out of adjustment. Again, you should be able to see the full 5/16"
hole....round, full-moon hole, no half-moon hole.....from one end to
the other without the bearing material in place. With the bearing
material in place the hole will be 3/16" and even harder to see all
the way through. This is just another one of those incidences where
the factory maybe turned out the parts a bit too fast without proper
jigging when welding....I'm talking about my 1994 Kitfox, not the
latest ones.
