Dissasembly help

[Kram]

Its usually getting things back together thats the problem, but this part I can not work out how it is retained. It is the air adjustment valve on the back of my r150 spray gun. Parts 17,16,15,14.

17 rotates half a turn, moves axially about 0.5mm. Any ideas how it comes out?

A good pull?
O ring 15 probably holds it.
Or you might have to unscrew it and remove the o ring to get it out.
What holds the whole assembly into the gun? 14 or 16?

There is also a good chance the “collar” 14 or 16 is Loctited in.

Part 16 in diagram looks like its threaded, and the body has a thread to suit.
17 does not pull out, even with tools, although Im being careful not to scratch it.

Given up I have no idea how to get it out and I dont want to risk it.. so drill a hole somewhere else
M4 tapped hole and temporary grub screw just infront of the lever pivot.

When the lathe is back together I'll make a very short m4 to schrader adaptor for the other tpms, the gf3 adaptor is m5.

Perhaps there's a retaining screw accessed through the air port?
