Step one is to consult the logs and see how old that one is, and when it
was last OH.

My rule of thumb is not to OH gyros with previous OH history. I just
replace them.

There are a number of good gyro houses around if you decide to repair that one.

Otherwise, call Spruce or Chief about an RC Allen or Sigma-Tek new
gyro. You can get vacuum warning flag and internal lighting as options. I
highly recommend the vacuum warning flag if you don't have some other means
of alerting you to a vacuum pump failure.
