[QUOTE="Evilspyderman, post: 9693057, member: 78762"] This is very good advise IMO. I am and have been a Blackhawk Helicopter Mechanic and Crew Chief in the Army for seven years. I have spent two years of that deployed to Iraq. Any place dust can stick to moving parts is very bad. I was doing my pre-flight inspection one day and found a problem that kept me from flying that ACFT that night. After my short flight I came back to fix the problem because it was on my assigned airframe. When the ACFT was reassembled 10 days earlier from a scheduled Phase Insp (like a overhaul every 360 flight hours) dust had gotten inside the tail rotor assembly. As I removed componets to fix the small fault I found earlier I started finding a lot more problems. There was extreme damage to all the close tollerance surfaces, it looked like someone had carved them up with a dremel tool. Keep in mind these pieces are titanium. $300,000 dollars in parts later and it was ready to roll back out on line. Not to mention nearly 250 man hours for all the maintenance and the follow on maintenance to get it fully mission capable again. However there is a substance we use to lubricate metal to metal surfaces. It is a spray on dry film lubricant. You spray on a light coat, just enough to cover all the shinny metal surfaces. It takes approx 24 hours to dry. When it starts to come off it simply flakes off. It will last a long time when the surface your applying it to gets cleaned very well prior to applying it. Here is a similar product to what we use on the ACFT. [url=http://www.drillspot.com/products/279987/Loctite_39895_Moly_Dry_Film_Lubricant?s=1]Loctite 39895 Moly Dry Film Lubricant[/url] [/QUOTE]
