HW/Weihrauch Dry HW95 problem Resolved.

[.20calguy]

Hi gang.
I spoke with Shane at AoA, and he said that nothing I said, scared him. He said to pull the stock and have a look for any damage. He asked what I had to work with for lubes, and he told me to lube it if it's dry.

That gave me the green light to contact Mycapt65, (Ron), for some guidance. He asked for pics.
Pic 1 spring at the trigger end!

That looked good.

Then he said to lightly lube the roof over the spring.
Using the tool, Ron suggested I checked the roof and the entire spring cavity wall. It was dry. So I gave it a thin lube with said tool.

Ron also said to grease the slot edges, then I gave it a test, and the friction/resistance is gone.
Let's shoot.
Thanks, Ron, and all who contributed.

i can probably use this on one of my guns , Thanks . (what is that Greasing tool ? )

What I see of the cocking slot looks ok. Do you think it was the Zombie Roof?

 

[Hateful McNasty]

Maybe it was just deburring itself..lol

Lube kind looks dirty for newish IMHO..

Thing is I'd of just snatched it apart and followed clean ,inspect , deburr, fresh proper lube and got going shooting ..

Like I said doing that don't affect the aoa warranty ( or pa if a R ). Normal water and yare stuff expected to be dealt with .

Nylon box tape, the hard plastic strap that you have to cut off of a package. He mentioned, tie wraps that will fit around the spring work

It was the shoe binding in the slide during the cocking stroke. Greasing the slide rail, upper and lower was the fix.
I had AoA's blessing on this project.

As long as it's working to your satisfaction that's what counts in the end .

I just acquired a new to me HW95, this is a common problem with recent Weihrauch guns. I pulled the thing apart and lubed the spring with Air Rifle Headquarters heavy tar. Then I reassembled it and bam! Back to the Weihrauch feel that I’m accustomed to. No spring buzz or twang. Often people are quick to put a tuning kit in them, but I don’t have a problem with the stock internals. They just need something to dampen them.

Well if the seal ain't chewed or knicked up from them shoving it in through the cutout razor burrs your good to go shoot the factory stuff some .. and I also keep a few arh seals handy ..lol

One thing you did hit on is I noticed after covid guns are lacking in quality control or something going on . I guess it's more important for them to make expensive novility guns instead of concentrate on there everyday bread and butter guns ... Lol.

It is a little different.
I did not lube the spring as it was sufficiently coated with some sort of moly. I lubed the shoe slot because the shoe was.binding. I also put a light coat of moly on the receiver walls.

What you're referring too is not lubing a dry gun, it's a modification being promoted to reduce spring buzz.
In the end that will make a mess that will likely find it's way into the chamber.

I'm glad to hear the problem is resolved. It sounds like a great gun. Be Well 20 cal, dito.

Great shoot this evening!

Glad you got it figured out. It's a beautiful gun!

I understand your concerns, but I have an R1 that went 7,000 shots with the same treatment before performace fell off and I replaced the spring. I never had a problem with dieseling and cleanup for rebuild was quick. I apply sparingly and have gotten good performance and no negative issues. Your mileage may vary….

I heard some folks were packing their springs with grease to dampen the spring noise. An idea that I can't see being a good one. The grease will splatter from the spring onto the receiver walls, the piston, which only seals going forward, gets pulled backwards over the grease covered cylinder wall, then compresses grease. So..

 

[coop709]

Not the way it should be done. The spring just needs to be lightly covered. When you put anyone’s kit in, they instruct you to put a light coating on the piston. The seal will sweep back the excess. Initially, you will get some dieseling, but that resolves itself quickly. For that reason however, I won’t chronograph a rebuild for a hundred shots or so.

If the guides fit the spring fairly snug this will take care of the twang in the shot cycle, pretty much. I only smear a very light coat over the spring coils
just so it's not dry inside the piston. I use Krytox but moly or your preferred lube will work. The black tar
was a cheap way for people to deaden the spring twang, but not needed if the tune is done right.

Isn’t it just the spring guide that quiets the spring?
