I assume that if it is used for assembly, its used for normal operations. I have not found out what "No.10 Aviation hydraulic fluid" converts to yet. So if anyone knows let me know.

I have heard a lot of stories about squirting this and that into the system to keep this and that from corroding. Anything from "light machine oil" to "pneumatic tool oil" to "hydraulic fluid" (original 5606 and the new synthetic types for example), etc., etc. Maybe 5606 is good... I really do not know. ANYWAY..... I did it. I put pneumatic tool oil into my 50. The next thing I knew I had trouble with the pressure regulation. Turns out that when you get oil on the pop-off valve seal, it does not want to seal as well, and my pressure regulation went from 50 atmos, to about 35 atmos. Next thing I knew, I blew the seals out of the landing gear actuators. That just sucks, and if you have never R&R'ed the landing gear actuators on a YAK-50, let me tell you it is not really a ton of fun. Then there is the matter of finding new seals. Maybe it was because mine were too old to begin with and just needed that to make them go bad. Who knows? I sure do not. Bottom line, I think it is a better idea to pull the landing gear actuators every "so many years" and just replace those seals anyway, and when you have the mess taken apart, have it treated for corrosion, by any method you so choose. My personal opinion is simply that it is much easier to ruin the seals by adding "stuff" into the system than it is to have the darn things corrode to the point of failure. A rebuild every "X" number of years is possibly a better solution. But,... it is very possible I am dead wrong. Regardless, I tried it, and will never do it again. Mark Bitterlich p.s. Adding a tiny amount of lubricant after a total rebuild to allow everything to go together and seat is another story. I'd use a DROP or two of castor oil. If that much. ________________________________ From: owner-yak-list-server@matronics.com on behalf of keithmckinley Sent: Thu 9/24/2009 7:44 PM Subject: Yak-List: Re: Remanufacturing Russian Check Valves Aircraft Hydraulic Fluid MIL-H-5606 is what I believe, but then again I was trying to get some more info as well. -------- Keith McKinley 700HS KFIT Read this topic online here: http://forums.matronics.com/viewtopic.php?p=264821#264821 ________________________________ Message 7 _____________________________________ Time: 07:14:28 PM PST US From: Subject: Yak-List: engine mount for yak 55 Hello group, I still need a upper right engine mount from the firewall to the mount ring, thought I had one located but after about a month of waiting the owner decided not to sell it.
