Walther CP3 problem

[Discocom]

As previous posts I bought a Walther CP3 in December. It was shooting fine and I was really pleased with it.

but...

I left the co2 cylinder on the pistol, went to use it and the cylinder was no longer screwed to the pistol!

closer inspection showed that the threaded portion of the brass part that the co2 cylinder screws into (part no. 264 see diagram below)

http://www.carl-walther.com/fileadmi..._2500311_c.pdf

was now in the cylinder.

At first I assumed the thread had stripped off, but I was able to retrieve the threaded section and in fact the threaded part appears to be more like a brass ferrule that has been soldered or glued onto the main part (although the Walther diagram shows it as a single part).

Ideally I'd like to get hold of part no 264 (anyone got a broken CP3 they don't want) or I need to somehow fix the ferrule permanently onto the main part.

all (sensible!!!) ideas welcome

cheers

Hi, can you upload photos, item 264 is solid on my CP1s

Are you sure you have described this accurately? If so you have a very interesting and mysterious case!

I have a CP2 which is near enough the same, part 264 is not brass, its steel, and the male thread is all one machined part, the 3 is the same.

You say brass threaded part? The only brass threaded part is a female brass thread, a part of the cylinder, it is supposed to be in the cylinder (and can't escape!) its not only the attachment thread to the pistol body but also holds the cylinder valve in place, and is secured in the cylinder by a locking ring, with an o ring seal between the locking ring and the part I think you are referring to, and that locking ring is some where between tight and b***y tight!

If you can find a drawing of the internals of the cylinder it will all become apparent to you how mysterious this is!

Is the locking ring still there on end of the cylinder? (it has a hex internal drive), I can't see how your brass threaded bit has escaped!!!

I'm bemused by the cylinder came off when stored!!

Have you ever taken the cylinder off since you've had it? If not I'd suspect an incredible bodge had previously been done with the cylinder miss assembled?

Interesting!!
Have Fun

Part 264 is a 1 pce male unit and used on many Walther CO2 models.

You may find a replacement here:http://www.waffencenter-gotha.de/shop/index.php or on egun.de

Hi Everyone

Thanks for the comments.

Just to clarify the part I mean is 'male' and machined from brass, it is secured with 2 allen pan headed bolts into the receiver and sits between the (removable) co2 cylinder and the receiver and also secures the spring loaded plunger within the receiver.

Part number 262 is definitely brass (at least it is on my CP3) As Robin said the part is similar on the CP2 (part 304 Aufnahme) I think the CP1 is of different construction.

What seems to have happened on my pistol is the the pressure on this part (from the nearly fulll co2 cylinder) has caused the threaded part of the 'Aufnahme' to detach. As per Robin the fact that it is in two parts may be a 'bodge' from the past possibly because the threads got stripped?

Looking at the Walther diagrams, the part looks the same on the Walther CG90 (part no. 49) http://www.carl-walther.com/fileadmi..._2490544_c.pdf

and I've found it available for euro 80 at https://www.schiesssport-billharz.de....-49-Aufnahme1

These pictures show the valve internals that screw into a brass end cap on the cylinder. The mating thread on the pistol is one piece that bolts onto the pistol receiver. It sounds like the end cap of the cylinder has come unscrewed I don't know how as they are f'ing difficult to remove.
