: Shadow 1000 piston seal
: October 03, 2007, 04:06:39 PM
Does anyone know where I could get a replacement of this part or how to repair it? Mine broke about a month ago and I was saving up for a RWS 34, but if I can fix my baby, I'd gladly go that route (its much cheaper :D) Info is much appreciated!

You might also want to get a better spring and some lubes to tune your shadow.

Also think about CDT's GRT-III trigger. Then you will have a beautiful shooter, that will get quarter size groups at 40 yards.:)

1-800-724-7486, part # C1K77-002. If you ever need a spring, the Crosman spring is also a drop-in if you use the Crosman tophat (C1K77-010 and C1K77-005).

Thanks guys, I just ordered the seal, 12 bucks. Lot different that 125 or 200 :) THANK YOU! I'll ponder that trigger, make reassembly any easier? I don't even know if I'll be able to get her back together!  :o Gonna hunt that down online.

Seconded, and thirded! The GRTIII is the best $32 you can spend on a Gamo.

You didn't pull the trigger mechanism apart - did you? All you have to do is remove the entire trigger group as a unit.

CDT's trigger does not replace the entire trigger group, just the blade. The action just has to be out of the stock in order to replace the trigger, nothing else has to be dismantled. So you could install the trigger right before popping the action back into the stock, or do it later. Either way, it's an easy install.

Lmao, yes I did  :0. Its completely apart. I didn't know that the whole assembly came out when I was trying to get the piston out until all the pieces were out. I've had the trigger out before, obviously its out now, so if I get it I'll definately know how to put that baby right on in ;). I guess I can get to work reassembling the trigger group until the seal gets here. WOO! I'm stupid! :D

Nah...you aint stupid. Just didn't know. But now you do...and that why its nice ta be here... :)

Very nice forums, I must say. Seems everyone is EXTREMELY nice and helpful :). Already saved me 100 bucks :D but might be only 70 if I get this trigger assembly done, get that new trigger :)

Does anyone have pictures of their trigger assembly? I can't seem to get mine to come together right, and I already had parts out that I want to put back in (I was a mod freak a year ago). Been about two months since I completely dissasembled it as well. Best I could find online was this http://www.airgunsmith.com/1/gallery1/trigger2.gif and its not helpful at all, lol.

Well, I think I may have just found the cause of the busted seal. One of the pieces in the trigger assembly was busted, broken in half. I'm guessing one caused the other, don't know what happened first. I think the broken part was the one that caught the piston. Just found the other half after looking around, I saw the pieces didn't match up with the assembly picture and noticed there was a very rough edge. Also seems I'm missing a spring.

I JB welded the broken part, but highly doubt it will last if it has to hold very much pressure. I'll let you guys know how it goes once the new seal is here, if it'll function still. My best guess as of now is that it'll function, but probably have the JBed piece rebreak after the first shot. Worth a try though, already got the seal on the way, lol. Seems FUBAR.

I think I'll be looking at those RWS 34s more closely ;)

It is my understanding that the trigger assembly you have is very similar to not only most every Gamo on the market, but also several others as well. Chances are good you can find a relpacement part for the piece that is broken rather than risk damaging the rifle or worse yet, injuring someone.

: I think that's kinda unusual...
: vinceb October 09, 2007, 12:59:37 PM
By all means, let us know which part and how it broke!

A Crosman Quest trigger assembly might work ($13), but I've not tried the swap.
: RE: Shadow 1000 piston seal
: October 09, 2007, 02:07:32 PM
Yeah, I was kinda doubting it could be fixed with anything too, lol. Figured I'd try though, I didn't know they would sell any replacement parts! Part that broke would be 15D in the picture, missing 15N (spring). Should I try to find it online, try the Quest trigger group?

The seal came in today, soon as I learned about the busted part. I thought "how ironic!". Maybe by time I get to shoot it again I'll have all new parts  8). No clue how it broke though... I took 15t out a while ago to lighten the trigger pull, maybe thats what did it? Either way, both the part and the seal went right around the same time. I was shooting and a loss in power, a sound that something was loose (thought it was the piston after seeing it) happened at the same time. It kept shooting too....very strange. Not making any sense whatsoever to me.

Thanks for the offer fix! I'll gladly pay for the parts :)
: Taking 15t out won't hurt anything.
: vinceb October 10, 2007, 09:07:09 AM
When I get a chance, I'll try a Crosman trigger group in a Gamo to see if it works.

: October 10, 2007, 01:32:57 PM
Thanks guys, I tried googling crossman quest trigger... got nothing. Where do I get it my google masters? :D

You guys are much too nice :)

Edit: Why you guys think that might have broken? I was assuming 15t was the culprit...I'd put at least 3k pellets down the tube with her like that, different tolerences for that long made it finally give out? Was right where the piston (I assume it catches on that part) would catch it, maybe 1/16th of an inch back max. Never heard of this.

1-800-724-7486, ask for "parts", and order part #C1K77-029
: RE: Shadow 1000 piston seal
: October 18, 2007, 09:38:29 AM
Holy god guys...well, I got the trigger assembly today, and CAN'T get it back together! I think I may also have another broken part....are there 2 or 3 springs? Looks like 2, with one snapped (the smaller one).

So, I took out the broken part, put it together how it looked like it should go...and it cocked. I was like sweet...ready to go. Couldn't find pellets, went and bought some. Got home, loaded up, pull trigger, nothing. So, disassemble, sear dropped, but nothing. So, try to pry it out with screwdriver (safety glasses on, gun pointed at very thick wood), but still no go. So, I ended up taking the pins out and having the spring fire back on a pillow. This little thing is causing so many headaches!  :emoticon:

Anyone mind walking through what goes what way in reassembly if taking the smaller spring out didn't mess it up?
: Did you say...
: vinceb October 18, 2007, 09:55:37 AM
...that when you popped the sear down, it still didn't fire? Are you sure the sear was completely disengaged from the piston?
: RE: Did you say...
: October 18, 2007, 10:34:44 AM
I'm not sure I had the trigger group in right, I think thats why it didn't fire. It disengaged from the trigger, dropped, but didn't fire. Seemed to me like it was still hanging on the piston...when I had the spring out and pushed the piston, it wouldn't budge. I had to take the sear out, drop the assembly, reassembly the assembly. Only when the assembly was out did it finally come loose.

I must be doing something wrong. I can't see how it would be messing up this bad otherwise, unless it was a fluke? I'll retry, one more time!

ETA: I put the sear under the little lip, seems thats the correct way. It won't fit right if it isn't that way. If it is the other way is pretty much what I'm asking, and how it would be fixed :) Sorry, takes me some time to word stuff right a lot of the time lol
: RE: Did you say...
: October 18, 2007, 11:35:43 AM
Well, proof that beating *_*_*_*_*_* makes it work! Sort of.

I got frustrated, because I manually took the sear down to allow it to fire. And it did...so I got jacked that it was the only way it'd fire..and did it a few times. Finally, the trigger started to work!

Unfortunately, the spring that broke seems to be a major one for power...because the pellet will not leave the barrel. WOO. :emoticon:  :emoticon:  :emoticon:
: RE: Did you say...
: October 18, 2007, 12:20:34 PM
When it broke? 15t wasn't in there at all, I took it out for a lighter pull. Safety as well, never used and just got in the way. I'm always tearing my stuff apart to see how it ticks, mainly guns, so I bet I might do pretty well as a smithy one day, if I ever gain some common sense ;) I'm SERIOUSLY lacking in that department...I was at a stop light today, at the entrance to Wendy's. Guy with his turn signal on going the opposite way, and I just waved. He mouthed "*_*_*_*_*_*" and I was wondering why...then I understood and backed up :D

I did manage to get her to fire, though. Part of a broken spring, and very liberal oil (figured she was toast anyway). Got maybe 20 shots in, sighted her in, two shots to see if accuracy was there at all...seemed it was. I think oil got on the trigger assembly, because all of a sudden I heard "squeeeeek" when I cocked it, lmao. Then the sear wouldn't catch. BUT, with tons of help here, I did manage to reawaken the dead ;) thanks fellas!
