From: doug sapp 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. Doug On Tue, Aug 25, 2015 at 5:25 AM, JL2A wrote: > > 'Twas the nose gear actuator!

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 On Tue, Aug 25, 2015 at 10:11 AM, Byron Fox wrote: > Good to hear from you, Doug.
