I need to replace the upper hammer spring on a CD O/U 12 ga. I've never worked on a CD before. Does any one know where I can find a schematic on line.
Thanks.
Thanks.

CD imported a bunch of different over/unders from a bunch of different places over the years. Some of them are ridiculously expensive and are right there with the greatest shotguns in the world. Others are not as great.
In the 70s, CD was importing Mirokus. Later, Browning started importing them as the Citori and CD started importing Spanish guns. The Spanish ones are the hardest to identify. Apparently, just about everyone in northern Spain has his or her own gunworks. I don't know much about the importing history after the Spanish guns.
Try and give us some of the markings and we can point you in the right direction. If you are lucky it might be a Miroku and Browning Citori parts should work fine.

Cd o/u
Thanks for the reply. It came in the original case with Browning embossed on it. The Model is Venture. It has the adjustable butt pad and REAL nice wood.
I just looked, it says MIROKU made in Japan.

There is a gunsmith in Lake Havasu City AZ that specializes in Miroku and Citori shotguns. I was getting FTFs with my CD Miroku and I sent to him. He must have fixed it right, because I've shot 1500 - 2000 rounds through it with no problem. You can find him if you do a google search. He also has the springs you need.
havoc7usmc,
If the Miroku is like the Browning Citori (and I think it is), here is how to do it.
Remove the recoil pad with #2 Phillips screwdriver. Then use a large straight tip screwdriver to remove the stock bolt. Once the stock bolt is out and with the barrels still assembled to the action, wiggle the stock up and down slightly while pulling rearward on the stock. It helps if you have someone to help steady the barrels while you do this. If not, just place the muzzle end on the floor and wrap your leg around the barrels/action while removing the buttstock. This should remove the stock from the action.
With the hammer in the lowered (fired) position, use needle nose pliers or something similar to compress the hammer spring which is around the upper hammer strut. You can even use a loop of strong wire to do this. It's best to do this with a sheet or towel over your work, because if the spring or strut goes flying, you may have a hard time finding it. Also wear safety glasses while doing this.
Once the hammer spring is compressed, the strut just slips out of its recess in the rear of the hammer. Again, be careful not to let the spring or strut fly across the room. Also, while you have access to the hammer/trigger works, clean it good and lightly oil it.
Now replace the old spring with a new one. Insert the lower end of the strut into its recess in the frame. Again compress the spring with the strut inside the spring until it is compressed sufficiently to slip the upper end of the strut into its recess in the rear of the hammer. Once again, be careful not to allow the spring or strut to fly across the room. Wear safety glasses.
Once you get this done, put the stock back on and install the stock bolt. Don't forget the washer that goes under the bolt head. Tighten the bolt snugly (about 8 to 10 foot-pounds of torque). Reinstall the recoil pad.
Then have a beer and congratulate yourself on a job well done.

Thanks pete409
I finally got it in and what a B&*#@, it is an older one that use the clothes pin type hammer springs..pre centre. I ended up talking to the guy that made the springs, who worked for CD for 30 years. He gave me some tips and said it is one of the hardest hammer springs to replace and expect to get a few bruises putting them in....he was right.
