Use care in fitting replacement brass (bronze?) nose gear
bushings.
The inner strut, which slides back & forth through the
bushing, wears unevenly. The section of the strut in contact with the bushing
while taxiing wears the most & will be slightly smaller in diameter than the
strut farther up where the bushing contacts it when the strut is fully extended
(in flight). If the bushing is fit quite close to the size of the strut in the
taxiing section, it can bind at the in-flight position. Believe me, this can be
an exciting situation! After installing a new nose gear bushing the first
take-off went fine until I tried to make the first turn & discovered
the yoke wouldn't turn (& my heart rate tripled!). It took both hands
to finally force the yoke to move. You can imagine the very jerky flight around
the pattern to get back on the ground. And on the ground all was fine because
the new bushing had been fitted to the taxiing section (slightly smaller in
diameter) of the strut.
Hope I've explained this OK.
