safety wont move to the safe position, what to do?
texken. I took one apart and here's what I found.
The safety linkage rides onto a shelf on top of the trigger to engage the safety. If the safety linkage is too long, it runs into the trigger rather than riding up onto it, blocking it. If you pull the pin out of the trigger and catch the trigger spring, you can remove some metal on the shelf of the trigger until the safety linkage slides freely onto the trigger shelf and locks it. What I found is all the machanisms need oil to test otherwise it binds up. Once you file the trigger shelf to the point the safety linkage can slide onto the shelf, polish it until it's smooth with 220 sandpaper.
Here's some photos to help illustrate.
The tit sticking down off the safety arm has to ride up onto that shelf on the top of the trigger.
The safety lever is on top, the linkage goes down and behind the trigger.
Here's the three pieces out (Yes, there's a funny s shaped spring involved!)
The square thingy and the square holey dealy in the meck-a-nysm
The shiny flat surface just above my thumb is the surface to polish until the safety slides onto the trigger correctly
You'll have to remove the buttstock, breech bolt stop (1/2" long L shaped tab that stops the breech bolt from going all the way back and falling out) and the breech bolt from the rifle, and this cartridge cutoff.
Don't drop the spring. I use assembly goo to hold the spring in place when reassembling. Plain grease might work, or crisco/butter in a pinch.
