I've removed the screws, locating stud and inner plug. The valve doesn't want to budge. It's my understanding that the 180 doesn't require a special tool to loosen the valve. What the best way to remove it without damaging it? Thanks   Posted: Mon Feb 23, 2015 8:37 pm AirGunEric Site Admin Joined: 20 Jan 2007 Posts: 6910 Location: "Out There" You need to remove the stock bolt (rod) from the bottom of the tube and the breech screw (in the breech, top of tube). I believe the 180 does not require a large screwdriver like the 160 (double check this- do you have slots on the valve head when looking down the tube at the front of the valve ('front' is facing the Co2 cap)) if not- then you need to knock it out with a dowel (from rear, valve comes out the front) as the seal has likely 'glued' it to the tube. If you have the slotted valve top- get a large screwdriver in there and rotate it before knocking it out. _________________ ` I'd say "I care." But I'd be lying.

I appreciate it! There aren't any slots, but there is a pin in the middle of the back of the valve. I'll try tapping it out with a piece of PVC so I go around the pin. I thought it should go out the front, but I wasn't sure. Thanks again. Big help.   Posted: Tue Feb 24, 2015 12:02 am AirGunEric Site Admin Joined: 20 Jan 2007 Posts: 6910 Location: "Out There" The 'pin' is the valvestem- avoid beating on it if you can (a wooden dowel with a hole drilled in it may be useful). _________________ ` I'd say "I care."

I spent to much time thinking of ways to tap the valve out without hurting the valve stem. Never thought of drilling a hole in a dowel. I missed the obvious on that one.   Posted: Tue Feb 24, 2015 9:04 am Merhere New Member Joined: 23 Feb 2015 Posts: 4 Another question if you don't mind... Which parts get oiled during the reassembly? Are there places where oil should be avoided? Thanks.   Posted: Tue Feb 24, 2015 8:36 pm AirGunEric Site Admin Joined: 20 Jan 2007 Posts: 6910 Location: "Out There" It's a Co2 gun- a bit of oil won't hurt it, but too much oil in the valve will only shoot out the barrel or lock up the valve if you fill it with oil. A very small amount of oil on moving valve parts, as much as you like on exterior mechanical joints. Don't use oils with a ton of detergents- 30W engine oil, 3-in-1 or any of the airgun oils are fine in/on a Co2 gun. _________________ ` I'd say "I care." But I'd be lying.
