Hello, I was hoping to get some advice on the proper way of removing the compression chamber in my Crosman 114. This is my first time working on anything this old. I am in the process of replacing the seals. I have everything removed but the compression chamber. The exhaust valve, and check valve came out after using a small wood dowel and metal rod and trapping on the front side of the compression chamber. I thought this would remove the compression chamber also. It seems like it does not want to move at all. I saw diagrams with something about a chamber locating pin, but I do not see anything other then the stock mounting stud. And that does not want to turn, I'm thinking it may be soldered in there, like the stud is. Any words of wisdom would be greatly appreciated
