Here is something I have not figured out.
Before replying you may want to take a look at the front end of your coupe
or an assembly drawing.
A coupe with single fork nose wheel hits a bump while taxiing and all of a
sudden the nose wheel is pointing about 25 degrees to the right.
The coupe can be steered into right turns but not to the left.
When looking at the problem, the nose wheel is well attached to the strut
tube. The steel nutcracker is OK, all bolts holding the two halves of the
steering collar are tight and OK. the steering ball has the through bolt and it
is OK. The steering rod is OK. removed the floorboards and the swivel on the
bottom of the steering yoke is OK. All cables and chains are OK. The ailerons
and rudders and rams horns all line up but the wheel is still pointing
right.
I removed the steering ball and adjusted the threads on the steering rod
down as short as it will get and now the wheel is lined up with everything else.
it flies as well as ever, and steers much better than before the bump. But
that is not the way it was before...
So what happened?
What changed the geometry between the nose wheel and the ball on the bottom
of the steering column?.
The engine mount holds the strut in place and it has not changed
shape...
The steering column has not moved forwards or changed place...
