A person ignorant of modern Dianas (uh, me) is attempting to re-spring a Diana 34 T01 today.
All went well until I got to the final retaining pin. The safety protrudes into the opening - below are two shots with the safely in different positions.
What obvious trick am I missing? Thanks in advance... ☹️

You just rotate that pin 13 degrees while facing WNW with high barometric pressure and light winds from the east. Just wanted to chime in with something haha. Looks like you are almost there and what a fine rifle these T01’s are! Mine does have a scary trigger that I’ll get around to adjusting. No first stage and a bit above a hair on the second.

You have just discovered why Hector and others (including me) recommend using a dummy pin during disassembly. You can try inserting a small Phillips screwdriver or punch to hold that spring out of the way from one side while slipping the retaining pin in from the other side. Once the pin is holding the spring it should go right through. I just don't remember if the pin should go above or below the spring. I guess if the safety doesn't work right with the spring on one side of the pin you can remove the pin and replace it with the spring on the other side of it. I think the spring should be below the pin but I can't recall for sure. Perhaps somebody else remembers more clearly about the T01. For future reference you can purchase a pack of four Hillman Shelf Pins at Lowe's. They're five mm in diameter and the perfect length for dummy pins.

Thank you! And I just now discovered much the same thing on my own, and got the beast back together.
The curved bit of the safety (half visible in my second photo) slides below the rear retaining pin, forming the detent that holds the safely in the "on" (up) position. I pressed it down with a brass punch...whilst pushing the retaining pin in from the opposite side...simultaneously using my third hand to juggle the force on the spring compressor...concurrently streaming mighty oaths...and eventually it worked.
I'll be stocking up on those shelf pins! Thanks again.

Luthier...love your tag line.
Reminds me of a meal in a local mom'n'pop diner years ago, which included chicken-fried steak (copious gravy involved) and cornbread. As we finished up, the cute young server swooped by with a line you could only hear in East Tennessee:
"Can I get them plates outta y'all's way - or do y'un's wanna sop up?"

Direct link to the pins that Roadworthy is talking about. $1.24 per 4 pack.

LOL, I'm from Louisiana. I know people who refer to Tennesseans as "the gravy people." ;D

Frank, that's not funny! were all here to help each other! being a little funny is 1 thing, degrading is another! educating is 1 thing undermining is another!! ;)

Mike,i had a .177 T-01 34 years ago so i might be a tad rusty,….but I do remember using drift/dummy pins when I reassembled it. IIRC, you will want to have the safety in the firing position when reinstalling the trigger unit back into the receiver,….with a spring compressors of course. Seems like if the safety is orientated in the ‘safe’ position, you may run into an issue with the three ball bearing mechanism within the T-01 unit. Like I said before, it has been some time since I had that gun so my memory is a bit cloudy on the subject. Hope you get that diana back up and running real soon.

Not bad, actually - been called a lot worse! Let's face it, part of being a southerner is getting used to "sopping up" a certain amount of verbal abuse over the years...

Thanks everyone...I DID get it re-assembled and functioning correctly!

Glad you got it sorted out. It's definitely useful to have three hands, LOL!
Experience told you that if something is not going in smoothly, then you needed to check. Sadly, not all airgunners are that experienced and serene.

Keep well, keep us posted, and shoot straight!
