I have a diana 52 which is recently fitted with a Venom kit by one of my friends but after fitting the kit. Its safety not engaging. Rifle is coking and shooting well. Can you people list out the possible reasons so that i can get the problewm fixed. Please help.
The only thing that I can think of is that the spring that is part of the safety is somehow tied up in the two 5 mm pins that secure that action to the breach. The saflety flat spring has a "loop" in the rear that the rear pin goes through. This one tends to be easier. The front pin has to spread the spring. I have found that the easiest way to keep this all in order is to make some 5mm short pins that you use to drive the factory pins out. These pins keep the safety parts in place for easier reassembly. I made my 5mm pins by simply cutting off a pair of long stainless steel cap screw up above the threaded area. These are a bit unter 5mm and are not as snug as I would like, but they still serve the purpose really well!
Hope this helps or that you have already fixed the problem, it's been a long time since your original post.
it could also be that the guide's base is too thick and therefore is barely allowing the gun to cock.
Try restoring the original parts and see if the safety now engages. If it does, then the new parts are to blame and adjustments are needed. If not, most surely the safety simply got out of place.
The use of "dumb pins" has been amply documented here. USE THEM.
Gun is getting cocked very well and shooting well.The actual problem which i found out is...Saftey is not getting automatically engaged when you cock the gun its (safety) is not getting back fully. I have to manually take it back after that it works fine. I don't know what is the problem. I have ordered some parts from UK. (Actually cocking rod is a bit bent) then my friend will open up the rifle again....
so what do u think guys what can be the problem...why safety is not getting fully back...
Hello
You might want to check your cocking rod adjustment and the pivot points for wear & alignment.
I have had a Diana break barrel get enough wear in the linkage/piston areas that it halfway cocks the safety.
Cock the gun slowly. When the sear sets, see how much farther aft you can pull the cocking rod and watch the compression tube move aft as you do this. Another couple millimeteres should be ebough to set the safety. If it isn't doing this, your pins are likely binding the safety spring inside the trigger housing.
You can tell when you cock a gun to the point where the spring becomes coilbound, or one solid piece with no space between the coils. It has a very solid clunk at the coilbound point. It's hard to miss. If you pull the cocking rod back and the seer sets, followed immediately by this solid coilbound feel, then you likely have so much spacing in the gun that it'll cock but the piston stem will not move farther aft to engage the seer. IN that case, remove some of the spacing & you should be good. You may loose 5-10 fps in the process.
