So I have quite a bit of experience maintaining, and cleaning my Microns (well all my iwatas), but one thing I've never disassembled was my air valves. I've removed them from the body's, but never actually broke them down to get to the plunger spring. And take out the trigger plunger on top of the air valve. Well that was until today, and OMG what a little pain in the ass to get back in. I thought I was going to go crazy trying to get that back in.
/I have some pointed ones in mine that fit the valve . I got a valve tool too but just as quick with the tweezers. lee
I use a screwdriver on the needle packing. And yeah that spring was under a lot more pressure then you would think.
That's been on my Christmas Wish list for quite some time. I want it just for the needle packing driver, because that would make adjusting the compression on the needle a heck of a lot easier.
Just cut some tweezers down to fit. https://avwairbrushworks.wordpress.com/2013/11/08/airvalve-removal/
