Help Needed with Brocock Contour S6

[cea1960]

I went to shoot today and found the Contour out of air. I suspect a slow leak so I replaced the O-rings around the fill probe and now it won't go back together. The first picture shows the gap I'm getting when I tighten it down. The second picture is the metal gasket I replaced that when out, the assembly goes together, but with a leak. I measured the metal gasket against the original and found no discernible difference. 

What am I doing wrong?

edit: I just realized there is a sub-forum for tuning and repair. Mods please move if need be.

I noticed the air cylinder is not centered inside the barrel band. Loosen the band and let the air cylinder move a little. Then put in the fill valve. You might not have noticed the air cylinder move when you took out the fill valve if. It were mine I would move the band back a little and it would be out of the way permanently. Good luck..

did you put silcone grease on the seal if you dont it will be a nihtmare to put back in

I have two of these myself. I gotta say that these are my go to rifle more than my RAWs, Edgun, etc..

I haven’t experienced this problem yet. I wonder if the piece is getting hung up on the o-ring? Perhaps some more silicone grease around the piece and a little more elbow juice will do the trick. I also wonder if cocking or de-cocking will help?

You don't want silicone grease anywhere near threads it acts like seizing compound.

The barrel band doesn't encompass the air cylinder. Its sits between two fittings. Here is a picture of the assembly without the barrel band. As you can see, even without the band, the surfaces don't seat against each other as they should.

Where were you an hour ago before I tried silicone grease? It still didn't seat properly, and when I tried to take it apart, I got this...

 Now I can't get it to budge and it's getting marked up. I'm through messing with it.



New question. Where would you recommend I send this to have it fixed?

 

[Odoyle]

Clean the threads and remove the dowdy seal (metal washer with rubber o-ring in the center) see if it tightens all the way without it. If that's the case get a thinner one.

 

[Odoyle]

Heat it up and use a strap wrench or leather belt with vise grip.

Remove the stock and barrel for easier work around space.

I tried it and it will seat, but it doesn't fix the problem of why it won't go back together with the new dowdy seal, or the original. Somethings not right.

I got it off the air tube, but now I'm stuck again. I need 2 large chucks to prevent anymore damage. Leather and pliers aren't working, and my cheap band clamp just slips.

 

[Odoyle]

If you don't got the balls to do it send it to Troy (thammer) or Scott (Motorhead) you can PM either Or both of them.

I've got balls, but the wife keeps them in a jar.

I'm afraid known if I go any farther I'll mess it up even worse.

 

[Odoyle]

If you got silicone grease in the threads it's a seizing compound. Screws things up in many cases. Sometimes ppl get lucky and don't sieze up the threads using their brand silicone grease depends on their gun type too. Today's your not too lucky day I guess.

 

[cea1960]

Thanks everyone for your help, I'll contact Scott and see if he's interested.

 

[Odoyle]

You need a vise and couple wood blocks to act as padding plus leather belt and vise grips.

I wish I had the know how and patience to fix this, but I'm the kind of guy that can't open a book without some of the pages falling out. 

 

[Odoyle]

ARE YOU SURE the dowdy seal goes inside and not around the male Foster nipple?

DO YOU THINK I'M AN IDIOT!

Well, you'd be right! 

I do believe you are correct. Now to separate these two items so I can reassemble. Unfortunately I cannot find my Irwin Groove lock pliers. I may wait 'til tomorrow and go to a machinist friend and see what he has to spin them apart.

Damn Odoyle your good. I really appreciate your help.
