G50 vs Master Arm

[Stephen Wymer]

WD-40 was developed in the 1950's as solvent and de-greaser to protect missile parts. WD-40 actually stands for "Water Displacement - 40th attempt". According to Wikipedia, It is 50% solvent, 25% liquified petroleum gas, and 15% mineral oil( the remaining 10% is inert gas) That means 15% lubricant and 50% lubricant killer.

 

So basically all of the lubricant in your arm that keeps it from squeaking amongst other things, will be eaten up by the WD-40, thus leaving everything temporarily "lubricated" by the WD-40 ( I use the term lubricate very loosely, because the mineral oil does so barely better than water)

 

Eventually you will realize that there is absolutely no grease or lubricant in your arm due to the WD-40 having cleaned it out completely. I think that is probably not a good thing. I would listen to page 24 of the Archer manual as Sebastien pointed out.

not at all, instead the arm works great now. and I've already worked in all the worst conditions (sea, sand, wind and salt).

 

how would you clean it when due?

Take it apart. Not that hard on the G50. No need to worry about that at this point. A drop of teflon oil sparingly here and there in the future is sufficient.

Thanks to all of you for the help. Particularly to Master Chris. I'll get some teflon oil soon and try to put it where needed. Anyway now the arm works really great. The combination of WD 40 (bad, I'll use teflon from now on) and lower socket make it perfect. No more bobbling even at really really slow pace. GREAT!!!
