You can probably get rid of one of those washers between the springs.

Agreed mine only had one and I see no purpose for two....
 But that should not cause your leak, only collapse the springs more and made it a tad harder to reassemble.
Now I have read where people really had to crank on the nut to stop a leak.
 My two were both a PITA to loosen and tried to repeat the same effort of torque on reassembly.

Just a reminder.... that retainer nut is steel... those threads in that valve are brass.
Removing the extra washer will insure that all 8 pumps should dump. You may have to cock the gun before pumping. To store the gun with a couple pumps in it, simply hold back on the bolt, pull the trigger and ease the bolt to the closed position.

Not holding air. Darn. How hard do I need to torque that retaining nut? I felt like it started OK but after about 3 full turns got pretty hard, and I was concerned about cross-threading. Also wondering about that check valve that I creased with the compression tube or the neoprene vs. lead washer. The air is just blowing through, which would suggest the rearward seals. I'm remembering that old saying, "If it ain't broke..."
When I built mine, I ran the threaded part in all the way with out the guts. This gave me a sense of how the threads feel and also allowed me to count how may turns were required to reach the fully seated position.  I then marked my tool at the point it protruded from the cylinder with masking tape while it was fully seated as well to give me a visual reference to go with the number of turns.

How ironic... I rotated it backwards(CCW) and marked where I could feel the threads "start" on the tool.
Of Course you have to index the tool to the nut the same place and mark that too.
By "mark" I mean a line drawn with a Sharpie fine point marker...

Hey folks-I'm back.
Let me see if I can get to all the points.
Only 1 lead washer came out with the guts. The rearmost one.
I was also wondering whether there's a washer or seal at the front of the valve,
Where the check valve seats.

As for the retaining nut-I'm a little worried about buggering the threads in the tube.
I get about 3 full turns before it gets pretty tight, even without the guts in place.
Is that just the design, allowing for the proper torque? I'll get back with the exact # of turns I get before it gets tough. Reinstalling the lead washer made starting the threads impossible ( or required more pushing than I cared to apply) so I used one of the neo washers from the kit. Then I could get it started. It was when I was unsuccessfully attempting to start the retaining ring with the lead washer that I became concerned I'd buggered the threads. I doubt I did, though. They just weren't catching.

I'll say more after I have another go at it.

If you only removed one lead washer from the rear there is another one in the front. Leave it be, don't use any of the orings from the kit for the front of the valve.
   If you get something long and made of metal you can tap on the lip inside the tube. You will notice it doesn't make a metal tapping sound. Just a soft tap, like your tapping on a lead washer.
   You might have lead in the threading. Clean it out use a hard bristle toot brush or brass brush.

That makes sense, I'll do it.

Anyone know the tap size for the internal threads (for the retaining nut)?
Not that I cross threaded them or anything ... ::)

If you want to invest in a tap, then you need to buy a 21/32-32.  Yes it is wise to clean the lead out of the threads before reassembly. The valve retaining nut will go in with less effort.

Thanks a lot. At this point I will need that tap, and the help of a machinist, or send it away.

A temporary tap can be made from a spare valve retainer nut (preferably steel) by cutting several slots into it.

  One thing I did with my valve tool as suggested by another member here made it much easier to use.  Wrapped duck tape around it so it just fits inside the tube.  Keeps the valve nut square with the threads.

Thanks guys. If I have another go at it I will definitely be more cautious.
I may just cut my losses and send it to Mac1.

Lots of good advice on this thread.  If you want to see how the thing is put together, take a look here;





Several videos about the Dan's and Benji's, both use essentially the same valve mechanism.


So........ whatever happened?
