Crosman 13xx annoying clacking sound fix

Bushings & rings are used on all my pumpers.
Just a little something to help a Crosman short coming.
I don't know if they will lengthen the life span of the pump arm but, the use of these two parts will surely tighten the arm & motion & you can "feel" the difference. 

I prefer the solid pins from Dave @ alchemy air works but Melons are OK   Just not as slick as Daves,

That's the one I remember seeing. Thanks for posting the link.

BillK - Have you tried this out yourself?

As mentioned, all of my pumpers have the Mellon rings & bushings.  For a "drop in  the bucket"
price.....Why not?

Sorry Bill, I didn't read your post very thoroughly did I?

I would consider trying one of them out, but I can't get past the "clunky" appearance of the nuts on each side of the tube.

I've been using Alchemy AirWerks pins with the hex/button head screws. Much more streamlined looking IMO. http://www.alchemyairwerks.com/store/c15/Pumper_Must-Haves.html

To be fair though, I really don't shoot my 13xx's enough to worry about the play in the pump arm. I'm sure that Mellon's pins work great.

And, FWIW, I have Mellon FT pistons and valves in ALL of my 13xx's. Best deal out there for FT's IMO.

Dave at Alchemy Air has the best  pins and many other parts.  Plus he's a good guy.

I know I'm a little late in the game but this mod really helped me out a lot so I thought I might share my variation/take on this mod in case it helps others.  Thankfully I bookmarked it since I struggled to find this exact "clack eliminating mod" manually again lol.

I couldn't locate the exact sized rubber washer that OP used so the closest size I found at my local hardware store was 3/16"X1-1/4" washer which I believe is 1/8" or smaller in thickness. I was disappointed when I got home and realized the thickness was off by a lot but a little ingenuity lead this to be a perfect fit & made the mod even easier to install.

I simply folded the washer in half, removed the plastic pump stock, test fitted the washer by sliding it in place like a mini taco in between the metal pump arm. I chose to slide the washer forward so the edge of the rubber was protruding past the end of the pump arm approx. 1/4". Then, I used a drill bit and created a new hole for the screw to go through. I re-installed the plastic pump stock, tested it, no more loud clacking!

IMO Stinger177's mod was the best for longevity compared to some of the Velcro/felt mods since it's held in place by the screw. I think my variation might be a slight improvement since no cutting is involved besides creating a new hole & the fact that the rubber splits open down the middle and opens up when it contacts the pump tube. Only time will tell if this lasts as long or longer.

Lastly, the top contacting edge can be sanded down if your arm doesn't sit flush in the closed position.

Sorry I had trouble shrinking the pic so I couldn't attach it.

Sounds interesting. If you can figure out how to post one, I'd like to see a pic of your solution.
