Well, patience first of all. It's been a while since 've been into one, but I'll see if I made any notes. There are 2 versions of the Diana 5, an old one and a newer one, changed in the 1980's I think. Old ones have the knurled metal end cap held in place by a set screw, newer ones are plastic, along with other changes. 5G should be the newer one, no? Nick Carter in his airgun blog shows work on the old version, but maybe would be of some help; https://anotherairgunblog.blogspot.com/2008/06/diana-model-5-disassembly-part-1.htmlOtherwise just google and youtube.

I also have an older 5G and a 6G.I think that I'm making progress, but the sear, trigger, and safety still need to be installed, and these parts seem to be the trickiest ones to add. At least to me. All those tiny springs are intimidating.Again, advice is welcome.Thanks!-W
My notes are pretty sparse. But the order of re-assembly was;install piston- CHECKInstall rear cocking lever,leaf spring & pin, use screwdriver to hook spring to rear lever - CHECKInstall mainspring & guide & pin - CHECKtrigger, leaf spring, spring, safety - use slave pin to install - TO DOInstall rear trigger spring, frame & grips - TO DOThe slave pin is just a piece of whatever material you have that is the same diameter as the real pin. You use it to put things in place and then drive it out with the real pin so things stay in place. Yep. That's how I installed the rear cocking lever,leaf spring & pin.And for the little springs, I made this tool that can make it easier to get them connected where they need to be. Just a groove on the end of a short piece of steel, but could be any material.That's all I got. - That's a lot. Thanks!
Not to bust cajones, but, that's why you should ALWAYS take pictures, lay the parts out, in their correct orientation. Saves a lot of headaches.
Okay, I'm almost there!I can't seem to wrap my head around installing the trigger assembly, though.I hate to keep asking for help, but I don't have a background in engineering, gunsmithing, or other fields that some of you may have.What is the easiest way for a novice to install this trigger correctly?Thanks for any help!-Whirly
Is it that you can't figure out how logically things should go back together? Or is it that you know how it should go together but can't get the parts to cooperate? In the latter case, the slave pin might be the trick.You might try Umarex tech support as I think they used to be the importer, maybe still are. Or Dave Slade (https://www.airgunwerks.com/about.html), give him a call and see if he'll give you a minute of his time, or pay him to walk you thru it.Wish I could be of more help.
I wish I could remember. I just did a model 5, not long ago.I didn't keep the pictures of it, before disassembly. I do remember that the trigger goes in last, the springs are a bit of a pain in the butt.Wish I could be of more assistance.
OK it took me a bit, but here is a good trigger video Wait LOL It can be translated
You don't have to tear the other gun apart. Just take the stock off, and LOOK at how it's put together. Use a magnifying glass, if necessary.
