Gerald,
Another problem I had with the nose gear door was that the BID's on the top
of the nose gear tunnel cracked and sagged because I had not adjusted the
hyd. actuator to bottom out.  Thus, the nose gear strut would sag just
enough to not mash the sequence valve to close the door.  I installed an
angle iron across the top of the tunnel attached by a steel strap down each
side of the tunnel (brute force).  The angle iron is right behind the header
tank, about 1/4 inch.  Anyway, check the top of your nose gear tunnel.

  Thanks Dan, I thought that this (vibration) might be the problem and tried
various ways of tightening the fit (used rubber between the door and
airframe
etc) but apparently ground observers say my door hangs completely open in
flight and sometimes I would hear a short cycle from the pump and the
buzzing
would stop abruptly when it slammed shut. The current problem is that on
retracting the gear it doesn't close at all.

  I used to have the problem with back pressure in the down line..this
manifested as the nose gear door closing in 3 quick jerks as the pressure
bled
off during retraction. I'm pretty certain the current problem commenced
after
I replaced the valve assembly which solved problem number one (the jerky
closure). I wonder if the spool valve problem manifests itself in various
ways??? Do you have any other experience of this?
