Timney trigger on M48 Mauser - safety problem. Help!

[AlexI]

I just installed a Timney Sportsman trigger on an M48 Yugo Mauser. This model was described on midway.com as "recommended by Timney for M48".
I installed it according to instructions, dry fired with no problems, but then noticed that the safety would NOT engage!
The instructions describe this as one of possible problems, and suggest removing some metal from the cocking piece, the area that the safety contacts (looks like an obvious solution). However, it kind of feels like there is a LOT of metal to be removed, and I would like to get some advice before I start filing...

How do I estimate how much metal to remove? I tried to push on the cocking piece until I could engage safety, it looked like I had to move it at least 3 mm. I can't believe it is true (maybe I couldn't apply enough force to safety while keeping pressure on the cocking piece)?!

Are there any tricks involved in reducing this area? Can I screw something else up if I remove too much or at a not exact angle?

And finally, in case I do screw it up irreparably, is it possible to find a replacement cocking piece for M48? I would feel a lot better if I knew it is replaceable...

Please help me out with your expertise, I will appreciate any suggestions.

Thank you.
Alex Indman.

AlexI,

You can try this place for the replacement parts - http://www.tngunparts.com/yugomauser.htm. The guy is good. I ordered stuffs from him before.

Good luck,

You are probably going to have to remove .015"- .020" from the face of the cocking piece where it contacts the safety lever.

I use a bench grinder to do this, being careful to keep the cocking piece square to the grinding wheel, and then putting a bevel on top- the cut should look like a half moon when you are done.

Go slow, remove just a little metal at a time, reassemble, and try it again if it does not work.

The problem is taken care of, your advice helped a lot!
All it took was a little polishing (no metal removal to speak of) on the cocking piece face, and putting a little extended and polished bevels on top of cocking piece and safety itself. Did it all with stone and sandpaper(220).

I just realized why my original estimate was so much worse then actual problem - I was looking at the bolt taken out of the action, forgetting that when it is in and fully locked, the cocking piece moves back a little more. Stupid mistake, but I am just learning, this is actually my first bolt action rifle.

Thank you.

Good show! I was about to remark that .020 is a long way from 3mm, and wonder if the trigger is the right one. Seems it is. Just make sure you have sear reset. With an EMPTY gun, cock the firing pin, engage the safety and pull the trigger. Then release the safety without touching the trigger. If the firing pin falls, it's back to the drawing board, as you have an unsafe rifle.

Tried this test already, no problem there!
