Changing a Mainspring
 

I need to install a weaker mainspring that I bought from Wolf. The book that I have (The Gun Digest Book of Firearms Assembly/Disassembly by JB Wood) is very detailed on striping a Lugeer except for this part. What is the trick to getting it out and then back in. It looks like a rod through the hole in the bottom of the rod down the middle of the spring is used to push the spring upwards. Is this the case? Then, how difficult is the thing to replace?

See General Information and FAQ section! Have fun and please invent some new cuss words. I change out about 3 of these a week and I can do a full change in about 5 mintues, but I remember my first attempts were measure in the hours. A good long heavy punch just big enough to go through the hole in the spring guide helps bunches. The trick is to compress the spring on the guide before you put it into the gun. I dont use the twist method of coiling the spring anymore (see text) but I simply hold the end of the spring with pliers (you must hold it parrallel to the spring axis not perpendicular to it) and push with the punch through the bottom of the spring guide so that the guide passes through the center of the spring, then hook the spring guide over the end of the spring. They say Georg Luger could change one in the dark only using one hand. I would love to see that one! Thor

I think I will do a Photo/text story some time showing all the cool moves to do this! Thor

Amen to that, a flying main spring or guide rod REALLY could take out one of your eyes! I actually thing this is a good little project to help people. If there is enough interest I will do it! Thor

Recommend you look closely at the set up before removing. I use a nail set that I can get a good grip on. There is also a in and out side on the frame. Only can go back in on one side. The spring guide has to go up through the frame with the hook sideways to fit through the link then rotated to hook on. Also make sure the hook/link is down before you get the guide up through the frame, won't come down after the guide is up.
