My Icon's showed up last week and over the weekend I did some prep work after having some discussions regarding the adjustment knobs (before reading the cold weather thread). It was suggested to take the caps off and just use an allen key on the adjustment screw. Upon removing the cap and seeing a brass screw I decided to go a little different route based on my knowledge of brass screws in steel housings.
I'm not a shock expert, but I am an expert when it comes to using brass screws, pins, shims, etc. in hostile environments. I'm an Oilfield Explosives Field Engineer and I use brass screws exclusively in the equipment I send into oil & gas wells which are often under pressure & corrosive in nature. One of the ways I keep the screws and caps that cover them in working order (even in storage) is called "Positive Pressure Packing" and that method is what I'm using to keep the caps & adjustment screws in proper working order.
Here's a quick How-to:
Remove knob
Using an allen key back out (counter clockwise) the adjustment screw all of the way.
Apply NGLI #2 Extreme Pressure Grease (I use CRC Sta-Plex NGLI #2 Extreme Pressure Red Grease)
Turn the adjustment screw all the way in (clockwise) and then back out to set your base settings.
Apply grease to the cap set screw
Insert the set screw, run it down and then back it out to ensure complete grease coverage of the threads.
Pack the inside of the cap with extreme pressure NGLI #2 Grease.
Press cap on with your finger, do not release pressure while doing this. You will hear a slight pop as the air escapes and it should expel grease evenly around the bottom of the cap.
While still holding pressure on the cap, tighten the set screw. Wipe off any excess grease and repeat with the other caps.
You will have to repack the caps occasionally if you make a lot of adjustments as over the course of tightening and loosening you will start to form gaps in the seal. Before any adjustments are made wipe off any excess dirt & grime from the caps. To make sure dirt doesn't impregnate the grease seal, tighten the cap a couple turns prior to back out. This will force more grease out from under the cap expelling grease & dirt keeping it from getting under the cap.
Thanks
