Reinstalling vacuum DG

[Mike Noel]

I finally pulled my Mitchell (Edo-Aire?) vacuum DG and sent it off to
Bernard Ducasse for overhaul. For those following the new vs. re-new
debate, I'll let the group know how the overhaul turns out.

After removing the DG, I covered the exposed ends of the vacuum hoses left
dangling in the plane with plastic and did the same to the exposed ports on
the DG. Any advice on special things to do during the re-installation to
protect the new gyro?

Regards,
Mike

Mike;
Good that you covered the ends. Upon installation, make sure to keep
any dirt or foreign matter out of the gyro. I've seen little metal
shavings that probably came from the fittings, ruin gyros in a matter
of less than 100 hours.

... and of course replace the filters on the regulator and the vac intake. I
replaced all the vac hoses as well, but mine looked to be original equipment from a
'69 plane! It's cheap to do ($1/ft or something) and then you won't worry about bad
rubber inside flaking off later. I think an inline vac filter would be a good idea to
protect the new gyros against pump failure... haven't gotten around to doing that on
mine yet, though.
