Extra Part after Trigger Mod

[JimH]

I just completed my GRT-III mod and when I was done assembling the gun I found a couple plastic parts that I have no idea where they came from. Any ideas? I tested the gun and it seems to work great... smooth as silk trigger.

So what to do with these parts? the pin fits perfectly into the cylinder.

Hi Jim,

The cylinder is a roller that goes on the cocking arm -- falls off when you remove the stock -- part # 14300 on this diagram:

Good catch!

Used to know a guy who rebuilt V8's to drag race. He was finishing up one and had a couple of parts left over. It seemed to start and run ok. I watched as he went over to the trash barrel and tossed them in. ('Course, he went through engines in about three-four races.)

[JimH]

Thanks for the schematic. I think I see where it goes - Is it on right? Does it matter?

When I took the stock off again I also found a plastic washer about the same diameter as the cylinder. It was stuck in the grease near the spring. Must have fallen off as well? So now I'm still wondering where the pin and this washer go?

Thanks for all the help. I guess I didn't expect so many loose parts to come tumbling down or I would have paid more attention. Maybe a good thing to mention in the trigger mod instructions for us noobs.

Check out the "BC Washer" thread at the Gamo Gate;

http://www.gatewaytoairguns.com/airguns/forums/thread-view.asp?tid=24278&mid=192254#M192254    The plastic washer goes between the black plastic cylinder roller and the cocking arm/linkage.

The pin I have no idea where that goes......never saw anything like that when I opened up my Gamos.

Thanks gamo2hammerli

I did try putting the washer on first, then the cylinder. It didn't seem like there was enough pin there to hold both...but I believe you... now what about this other pin? could in now be inserted into the other end of the cylinder? I tried that but that's really sketchy.

Hope I can get an answer before too long... I really wanted to go out and shoot Saturday...

READ THE INSTRUCTIONS


If the installation instructions were read in their entirety before beginning the installation as instructed at the top of the instruction page, a person would see that all of that information is mentioned are in the installation guide. Also, I did not see the old adjustment screw in the pics. The instructions also show what parts are left over including the little pin.

Aptly put Bob.  As my father used to remind me throughout my youth, "When all else fails, read the instructions."

[JimH]

OK Bob, I get it.... Spanking well deserved. I did read the instructions but that was last week when I ordered the trigger. Shame on me. Sorry.

I did remove the old adjustment screw (step 7) but not until you reminded me. It seems to work the same with or without that screw. What does removing it do?

Thanks again for your patience.

Works the same with or without the old adjustment screw....I had accidentally broken off the old adjustment screw and the plastic nub that surrounds it on my Crosman Storm, before I installed the GRT III trigger and the trigger still works fine.

In some guns it may interfere with the trigger adjustment and/or cocking and let off.

Fired off a bunch more pellets yesterday and today and it's amazing how much easier it is to squeeze the trigger at just the right moment. Thanks for all your help.
