This is a pictoral guide. For those whom wish to repair themselves. Was doing this for a member and thought that others may want to see ...


Image

^ there is a fine specimen ... screw driver, alan key, number 6 torx.

Image

^ Removing compensator

Image

^ remove slide

Image

^Remove lever by turning it all the way

Image

^ Removing rear sights with torx bit ... I broke the adaptor hence the plyers (she's on there good)

Image

^unscrew safety/firing pin block

Image

^ Just pull the other side of safety out gently

Image

^ Remove grips

Image

^Watch out for this here spring it can fly on ya.

Image

^ Remove the 2 screws on the other side and this one

Image

^ Give the shell a little pry

Image

Watch out for this spring. Is not a nice one and doesnt like to stay put :twisted:

Image

^ Easiest way to put it back is by taking the black lever out to make clearence for the spring then squeeze

Image

^ The spring I broke is crudely illustrated above in blue. I am pointing at the spring that OSOK thinks is broken.

Image

^ Nice picture of all the peices

Image

^ To close back up, line up the rotating arm (green arrow) with its little shuffle groove and give a little squeeze. If your gun locks up completly after is closed, remove the tiny spring ( blue arrow ). This happened to me tonight, I find it to be a very irratating design flaw, down side is you will no longer have a lock up mode when the slide is open.

Image

^ To get the lever back in push the tabs down in order to give it clearence in the hole

The rest is the reverse of how it was taken apart.

Thank you very much for going through all that trouble, you just saved me a big headache... this pictorial is nice and easy to follow so i shouldn't have too much trouble, i'll start the operation on Sun and see if it's the trigger spring that broke, which is probably the case. I'll order us each 20 springs from umarex if i have to replace mine...Image



once again, thanks a bunch smokey

Hey thanks for doing that.
I had visions of little springs popping out everywhere and never getting it back together. I take your's is fine? :)
I want to polish the trigger and lighten it a bit if possible.

No problem. it was fun for me. Putting that cliplever spring back in does get tiresome though.

For the trigger, which I didnt take aprt in the tutorial, there is a lever spring directly behind the top of the trigger, you will need a small hook like tool to hold the spring back (compress) so that you can slip the trigger back in (I just used a bent hairclip). The rest of trigger assembly you see how it works when its apart.

Mine is still in working order minus the spring I broke (which allows the hammer to follow through). Trigger functions correctly (mind you the trigger arm is loser now) and cycles with hammer help.

Regards,

SmokeyBonez

I recently needed to service my CP88 and your tutorial was helpful to me, I do have a couple of additions that others may find helpful. Firstly the saftey switch will not come out unless the black lever is all the way down as it slides into it. Secondly your experience with the gun "locking up" after reassembly is not a mistake but a built in saftey feature for when the slide is open, you can put a dowel in there to simulate the magazine rod and the trigger will move freely so no need to remove any springs. I found more helpful pictures here as well http://www.airgunhome.com/images/cp88/. This gun is a puzzle but I can take it down without assitance now.
