How to pull the Receiver of the 5.1 apart


Wege

Recommended Posts

Good question, I am working on a WE Baby Capa right now. The first trouble was the hammer would not stay cocked and therefore unable to shoot the gun. I took it apart and tried bending the middle finger of the leaf spring and get it to cock perfectly and even shoot once maybe twice then it get's weird. After the first one or two shots it won't fully cycle and shoot a bb but will continue to cycle everytime I pull the trigger just the hammer won't come back all the way. This is most frustrating indeed. Any other pointers?

ok.

Look at the top of the grip, to the immediate left of the left side safety.

Can you see a small hole (about 1mm diameter) facing the rear at all?

that is where the small spring and rod go back in.

 

the spring, followed by the small rod... narrow end first.

I lost the spring for the thumb safety. I was standing up, holding the 4.3 with my left hand, with the left side facing up, the barrel pointing forward and slightly to the upper left, with the hammer up against my body. I wanted to see how the safety would be pulled apart before I actually did it, and after I just gave the safety the slightest pull with my right hand, the pin and spring popped out. Luckily, the pin was pinned up against my body, but I didn't see the spring pop out.

 

Generally, where and how does that spring pop out so I can get a better idea of where to search for the spring?

The spring typically shoots out towards the back of the gun, so it probably hit your body with the pin.

 

If you didn't see it pop out, are you srue it came out? I've had my hicapas launch that pin on many a time, but the spring doesn't always follow. I've looked and looked for it only to find it still in the gun!

 

I did loose the spring for my 5.1, eventually. I dropped it in some mud, and popped the safety off to clean out the gunkiest parts of it...and like an idiot, my spring dissapeared in the woodes. I found a slightly too big but workable spring in my toolbox, from an old Shimano XT shifter, but I bet not many of us have those things hanging around.

If it was still in the gun, where would it be? Would it be visible with the safety and hammer spring removed? If I shook it, wouldn't the spring just fall out? Or, would I need to disassemble it further?

 

Edit:

 

Yes, it's still in the gun!!!!!!!!!

 

Don't I feel like an idiot.

 

Thank you for your help Glenn.

I'm having some trouble with the hammer riding up now - the slide sometimes gets caught on it. Any ideas which bit needs bending/fixing/replacing? Or do I just need to file down the hammer?

A new hammer or sear could help...but the easiest solution is to simply file the hammer. I've done it on both my Hicapas, and my Mk23. It helps quite a bit.

 

Use a good sharp file, and go slow. Test often, so you don't take off more than you need. You can get a nice finish with a file, I'd google for tips. My polished hammer looks essentially unmodified even after filing.

just as a note.. I have seen a couple of the WE 5.1s where the frame is being dented by the force of the hammer hitting the firing pin/frame. I saw it pushed forward by approximately 1mm.... hyper extending the firing pin.

OK - I've had a look at the pics, and I'm not sure which bit is the sear...

 

Can anyone point the right bit out in any of these photos please?

If I cant replace that, then I'll just file down the hammer as suggested. Cheers guys

You are holding the sear in 021. It's the black piece to the left of the hammer in 019.

 

I couldn't get the hammer to keep down enough with the original sear or a new one when I got a stainless hammer, so I just filed the hammer down.

 

Looks kinda cool actually:

I also polished the flat sides of the metal frame and grip safety.

Okay - thanks very much for your help guys. You are on the list to add rep to when I've made enough posts.

 

 

that was ME holding it.. not him.. :P

 

(do I need a manicure?)

No, of course not, your nails are lovely :rolleyes: Oh and well done for an excellent takedown guide - great photos and good explaination. You are too on the "rep list"

I have a WE dragon A. It worked great for about 300 rounds, then it was a step function from working to Not working.

 

I am totally lost. My WE dragon A worked great on propane and green gas and then the next day, It would no longer work.

 

By not working I mean the slide does not recoil far enough to

load another round. I can manually operate the slide and then it

works fine. (If the frame rails need polished, the why did it work

great for 300 rounds? What have I missed on this and other forums)

 

I have taken the gun apart and tried the various fixes:

Removed slide and polished rear frame rails. (in hammer area only)

Removed breech and piston/o-ring tried numerous variations

of teflon tape/replaced o-ring. Cleaned/used pure silicone lubricants.

(using teflon tape in this area requires trial an error to determine

correct amount at the time of wear and angle of attack to ensure

proper seal else the loading nozzle will hang-up or release to soon.)

 

Investigated loading nozzle to ensure proper function. (not sure what happens here because it is so simple...

 

Replaced magazine with new one to try to ensure Mag not a problem. Used RED $20/bottle gas in old mag 1 time to ensure enough blow-back pressure. (chrono went UP 23 fps avg but still not enough blow back to load another round, no new markings on frame or slide to indicate a stoppage)

 

Have taken down entire lower to ensure proper function. (not much differect from RS on take down and operating requirements)

Have taken down entire upper to ensure proper function. Still do not understand blow back function, Not like WA, but would really

appreciate the knowledge or help.

 

Would like help to salvage this gun but understand this topic has been beat to death. Maybe, I just trash it and buy TM to use my two mags in...

 

Any direction or sugestion will be greatly appreciated.

 

Thank You,

Rick

Righto..

well.. here it is.

 

http://img.photobucket.com/albums/v634/weg.../Picture039.jpg

Take your bog standard 5.1 gbb pistol

 

After removing the slide (please read your manual!)

http://img.photobucket.com/albums/v634/weg.../Picture040.jpg

Please have these tools handy. (maybe a cloth and some silicone spray too actually to wipe clean and lube)

 

First things to remove are the thumb-safeties.  Start at this point http://img.photobucket.com/albums/v634/weg.../Picture041.jpg and move the safety up to here http://img.photobucket.com/albums/v634/weg.../Picture042.jpg .  Note: the hammer must be in the "cocked" position. 

 

To make sure that you do not lose two small important pieces, do as I did, and hold a hand in the way http://img.photobucket.com/albums/v634/weg.../Picture043.jpg .  Those pieces are actually where they fell, and have not been picked up from about 2 metres away.

 

http://img.photobucket.com/albums/v634/weg.../Picture003.jpg

put your punch here, and get ready to press it on through, pushing the pin out like so...

http://img.photobucket.com/albums/v634/weg.../Picture004.jpg

 

Now then, pull the punch out and you will see this:

http://img.photobucket.com/albums/v634/weg.../Picture005.jpg

 

Pull the hammer-spring housing out and have a looksie: http://img.photobucket.com/albums/v634/weg.../Picture011.jpg .  You can see the little brass pin keeping the spring cap and spring inside the housing.  This is where you put a 'new hammer spring' if you feel you need to.

 

http://img.photobucket.com/albums/v634/weg.../Picture009.jpg

http://img.photobucket.com/albums/v634/weg.../Picture008.jpg

http://img.photobucket.com/albums/v634/weg.../Picture007.jpg

http://img.photobucket.com/albums/v634/weg.../Picture006.jpg

Assorted pictures of the 3-leaf-spring and it's placement in the rear of the grip.  Not the slot that is in the grip that the spring fits exactly into.

 

http://img.photobucket.com/albums/v634/weg.../Picture010.jpg

Side note- See this point here on the spring? bend that big bit a BIT further (a hint..a smidgeon, not much, tiny (get the point here?)) to sometimes correct the grip-safety failing.

 

Now the plastic grip itself - http://img.photobucket.com/albums/v634/weg.../Picture012.jpg

here and here http://img.photobucket.com/albums/v634/weg.../Picture013.jpg are where you need to undo.  (Note - use a magnetic screwdriver.... it makes things so much easier when putting screws in, and pulling them out.)

 

It should look like this now http://img.photobucket.com/albums/v634/weg.../Picture014.jpg

To take out the trigger, you have to remove the magazine release.  Put your flat head screwdriver in, press and rotate (anti-clockwise?).  Now the mag release will come out and you can then pull out the trigger and trigger-bar.  Note the punch is pointing at the little pin holding trigger to trigger-bar.  This is where you attach your new trigger.  http://img.photobucket.com/albums/v634/weg.../Picture016.jpg

IF you want to change the grip over, and nothing else, well, you can stop reading, and do the 5.1 back up. :)  otherwise, carry on.

 

Inner bits:

http://img.photobucket.com/albums/v634/weg.../Picture017.jpg

Phillips head again.  Pull the screw out and then you can lift off the side piece like so http://img.photobucket.com/albums/v634/weg.../Picture018.jpg

( I am taking the pics with my right hand, and holding it with my left).  This is the easiest  way/place to get this piece off of the main part of the receiver. 

 

The next show the positions of the hammer, sear, and a part that I don't know the name. NOTE the wear that is present on the sear.  Intriguing that this part has gone for a year and has done this. Hmmm...

http://img.photobucket.com/albums/v634/weg.../Picture021.jpg

http://img.photobucket.com/albums/v634/weg.../Picture022.jpg

 

No bits!.. just silicon oil. http://img.photobucket.com/albums/v634/weg.../Picture023.jpg Note the position of these parts. :)

 

http://img.photobucket.com/albums/v634/weg.../Picture024.jpg

http://img.photobucket.com/albums/v634/weg.../Picture025.jpg

shows the spring that you need to remove.  Note how the long arm hooks in and underneath that shiny hammer pin!.. That is the hammer pin folks.  Take good care of it.

 

http://img.photobucket.com/albums/v634/weg.../Picture026.jpg

pulling off the spring.

http://img.photobucket.com/albums/v634/weg.../Picture027.jpg

pulling out pin.

http://img.photobucket.com/albums/v634/weg.../Picture028.jpg

note the small bit on the firing pin that fits into the groove of the dark metal housing.

http://img.photobucket.com/albums/v634/weg.../Picture029.jpg

slightly different shot again.

 

Unscrew the phillips head screw as you can see, pull of the little piece and you will see something like this:

http://img.photobucket.com/albums/v634/weg.../Picture030.jpg

 

To put it back in (after cleaning and lubing of course) you will need to hold it like so http://img.photobucket.com/albums/v634/weg.../Picture031.jpg or fluke it like this! http://img.photobucket.com/albums/v634/weg.../Picture032.jpg

 

This shot shows where the bits go back into, or how the correlate. http://img.photobucket.com/albums/v634/weg.../Picture033.jpg

 

http://img.photobucket.com/albums/v634/weg.../Picture035.jpg

shows how the firing pin should be able to be moved. You will see two pieces moving.

 

Now, put it all back together!.

Note: when putting the metal receiver back together, use the domed head phillps screwdriver, and STOP! when the screwing motion stops.  Any further and you will risk stripping the thread.  Like wise when attaching the plastic grip to the receiver.  Don't give it 'one for luck'.  The grip and slide is pretty much the only plastic on this gbb, which I find is pretty damned good.

 

And now put it back into it's home http://img.photobucket.com/albums/v634/weg.../Picture036.jpg (in this case a NATO M12 holster).

 

Any questions?

I have wei-e tech 3.8 high capa & wow you saved me money from this kick *albatross* intel.

my wei-e tech was going full auto (the hammer would not stay cocked or back)

It was the spring in the grip safety that caused the problem .easy fix take the return spring housing of by pushing out the pin on the bottom of the grip.there is a peace of metal that looks like one peace but splits into three metal tabs .the tab on the left has a small arc if it's not a small arc than that the problem .

 

this also is the way to make it full auto if you want !reply or email for more details
