Installed a Vortek PG2 Kit in a Ruger BlackHawk .177. Yes I did take pictures, but I'm too aggravated to load them up right now. I will post a little write up with pics later this week. In the meantime, the install was easy, however, I've spent hours trying to reassemble the trigger and safety mechanism. Thought I had it, but would not cock. Totally p*ssed off, had to walk away before I screwed something up.

Anybody have any pics or exploded parts diagram?

I tried searching the net. while I was trying to reassemble ( had the laptop in the garage with me) but no luck, having a couple of cold ones now to decompress, will continue searching.

here you go, just right click on the pic

the only easy way i found to put this trigger assembly back in is to have it all together with safety already in the assembled trigger part.

then i used two shortened wooden pegs to take the place of the metal pins, once compressed in the tube, you just push the pegs out using the original metal pins

I had that same problem once. I can't remember the exact cause, but I'd try plugging the piston into the trigger while in your hands, not the gun, and watch it move. I imagine the problem is the trigger refuses to catch and lock the piston? That's what most people have trouble with. All I can remember is there is an action when the piston is inserted all the way that resets the trigger and that's what wasn't working. I believe when that fails it will reset if you pull the trigger a bit to help it along, but whatever the case just watch it move and look for what's not happening. If all fails just take the trigger completely apart and reassemble. Several people have asked me to fix a trigger they took apart and now won't work, so I take them apart, can't see anything wrong, put it back together and they work fine.
Another thing; if the new spring assy is too long and won't let the piston go all the way into the trigger it will fail to rest. This is another reason to test it in your hands first to verify it works, then install it. If it's the spring assy you can look for a way to shorten it, maybe you left an extra part in, but most people have that problem by adding a shim/washer to boost power. If not and the spring is simply too long you can always cut a coil off.

Getting the safety back in is definitely a trial of patience. Holding the two metal plates to the side while pushing the safety in requires a very thin but stiff piece of metal to hold them. If you have at your disposal 2 strong magnets will hold them as well .

As I recall, part #55 causes the problem. It needs to be in the middle of part #57. Part #55 has a spring attached and does not want to stay straight. You need to hold #55 straight, I used mini needle nose pliers.

Thanks for your help, but I have no idea what you mean by holding the two metal plates to the side??

I was using a small flat screwdriver to center Part#55. At the moment though, the safety is no longer co-operating in sliding in place.

I installed the new spring kit, compressed it, and reinstalled the retaining pins. Then I tried to reassemble the trigger/safety. I don't understand what you mean about plugging the piston into the trigger?

Part #55 caused all my problems with re-install. It doesn't want to stay straight in two dimensions, center to length of gun and a cant top to bottom. If positioned right it will go easy. Three or four hands wouldn't hurt either.

if your gun's piston rod will not engage the sear when you cock it, i suspect you have part 51 and 52 in the wrong order, the one that has the little metal peg on it needs to be facing back and the peg facing down, i included a pic to show you what i mean, put those back in that exact order shown in the pic

I didn't remove those parts, I just popped the three pins holding the trigger mechanism together.

Sorry. One metal plate. With the safety out and the trigger in place if you look inside from the back you should see a small plate that moves from side to side. That little plate binds as you try to push the safety back in. It has to be held to one side while you insert the safety. A thin piece of metal or a magnet will hold it till you get the safety back in. Of course I'm assuming the black hawke is the same as the air hawke.

That's a bit of a relief, that's the order I've been reassembling in. Barrel wont cock, so it sounds like I have to pay closer attention to the alignment of part #55 like Joe Hickey and HarryEClark mentioned.

I didn't have this bit apart, but the spring #56 fits over a tit on part #55 and seats against some kind of steel plate at the end from what I see, is this correct? I downloaded a photo that kind of makes is look like it butts up against the safety, so I'm not sure.
