Remove the blue shell.
Then take out the green handle/plunger. Be careful to not let the spring-loaded catch pieces go flying. Take a look at the plunger head.
Remove the yellow plastic bit at the front. I could just pop mine off with my hands, but you might need a screwdriver or something to pry it off. With that gone, the seal can be removed as well.
Slice off the stub that the seal was mounted on.
Drill a 9/64ths hole in the center of the plunger head.
Several steps in one picture. Whoops. Anyway, mount the skirt seal (9562K46) however you wish. The best method would probably be to cut a 7/8" diameter circle out of some 3/8" thick polycarbonate and drill a 9/64 hole in the center. I didn't have 3/8" polycarbonate, so I used 1/4" and a #6 washer. For the front piece I cut a 1-1/4" circle of 1/8" (I think) polycarbonate and drilled a 9/64 hole. You could use a fender washer here if you had one. Whatever you use, it has to be thin. I tried a circle of 1/4" polycarbonate first since I had one already cut, but the gun doesn't work with a piece that thick. Assemble with a 6-32 screw and a nut or two.
You may need to cut down the screw port on the other side of the shell so it doesn't hit the screw here.
Lube up the skirt. Reassemble the gun. Refer to the first pic. Done.
