'Twas the nose gear actuator! Bench tested it and air just whistled straight past
the piston seals. Now for some freon, a sniffer and track down any other little
leaks
Thanks Dennis, got all new actuators in now and have switche dto light machine
oil rather than castor oil as I'm sick of the mess it makes on everything and
the fact I can't seem to find a solvent for the sticky residue it leaves everywhere!

Have we come to a consensus on machine oil being OK for the seals? Or is
another MMO discussion?

Anatole,
True, castor oil does leave a residue, but you will discover in time that
you will have more small leaks without it. It's propensity to gum up does
more good than harm in my opinion. Also I'd test the oil that you are
using to see if it's "friendly" as many of the modern tool oils will soften
the old technology seals and 0 rings which are used in the CJ. I would
think that a straight mineral oil would be the safest way to go.
Knowledge gained from inspecting exchange core gear actuators suggest that
many of us are using far to much light oil in our pneumatic systems. We
found that many core actuators had little or no high pressure grease left
in them, it would appear that it had been washed away by the light weight
oil. To much light weight oil also has a tendency to carry (flush out)
small bits of grit and junk down stream. These small pieces of old rusted
out standard steel springs, corrosion, and grit are the major killers of
your start solenoid, and flap and gear valves. We are now testing the
installation of a second SS pneumatic filter placed just before the point
where the air enters the rear flap and gear valves. I think this will
greatly extend the life of these expensive valves.

Good to hear from you, Doug. Would seem to indicate that the immediate need t

Blitz and all,
Yes, the fire is past us and we seem to have come away unscathed thanks to
all who helped. Many thanks to all those who sent their thoughts and
prayers.
The fire is still not under control so please keep those still in harms way
in your thoughts and prayers. Refresh the fire map I posted earlier and
zoom out, you can get a better idea as to the true size of this monster
fire, it's nearly beyond belief.
We are back in the office and all is good, a bit smoky but good.
Thanks again to all our friends,
Doug and Kathleen
