Well I just ordered a new seal and some super moly from AGH! I decided to bite the bullet and do a tear down to deburr and cleanup what I can then put a good seal and lube!
I noticed that the rifle started having more recoil and seemingly shoot slower with more noise!!!
So we can't have that ,thanks to all you guys help and all the post that has been made I realized I need to do some replacing of factory seal ! So hopefully I can makeup a jig to depressive piston enough to take it down! Wish me luck on that one I can't afford a brain cramp on this job! Lol. I will keep y'all to date as I go!

Hey Pappy,
Your going down the road most of US Hatsan owners have. With a tune the guns can be made so much better.
Just remember the downside, this voids the manufactures warranty, Hatsan will not sell you any (OEM) parts if needed (excepting seals).

So in my case, Hatsan USA will not sell me either a sear #1 for my Quattro trigger or the whole trigger assembly. I need to box up the entire gun and return it to them in AR. They want to fix and go over the entire gun. This will likely cost me $50+ in shipping (both ways) plus the labor/parts fees. Hence, I'm likely better off buying a new Hatsan 95.

My two cents...........

That's a pretty good sign the seal is nicked and will only get worse.
On the warrenty? Only you can make the decision to throw it away.
My AG's were used but even if I ordered a new Vortex version today? I'd take it down and chance it.
I mean, I know someone I could sell the trigger to if things go bad.

I bought the gun secondhand anyway so what warranty! Lol. If the trigger goes bad for some reason I am sure it can be fixed one way or another! I am not a gun smith nor do I have a shaper or lathe but I can find a shop or just buy a complete trigger that walther sells! Let's just hope I don't wear this one out! Lol

Well the whole warrenty issue is no longer an issue.

Take that sucker down and OWN it!

You'll have a blast doing it, it really makes it 'Your Gun' then.
You'll also get a look into what the Pro Tuners deal with.
I think that was the greatest insight I got out of the whole 'Do it myself' thing.

How did you compress the spring?

Privateer · « **Reply #6 on:** June 21, 2014, 08:06:33 PM »

I used the jack from my Dodge pick-up.
It may sound crazy but it's a scissor jack so has power that is way beyound what a Springer or Gas piston has.
I built a 'thing' against my bender in the basement to hold the AG's.
I did do the 1st Sniper under a Stake Bed truck frame the first time.

How much preload was there?

Privateer · « **Reply #8 on:** June 21, 2014, 08:35:04 PM »

3/4 of an inch. I took it apart with no compressor the first time. Just body weight.
I couldn't get it back together though.
I'm just to skinny to do that.

Pappywith4 · « **Reply #9 on:** June 21, 2014, 08:39:59 PM »

No worries here I weigh 240 lol but I will build something for the sake of building it!

SpiralGroove · « **Reply #10 on:** June 21, 2014, 09:54:23 PM »

Good luck Pappy,
Taking apart the gun is not a problem, you can put a small screwdriver in one of the holes supporting the trigger housing and then shoot the spring/pieces in a large can padded with rags. Putting the gun back together is another matter.
I would definitely use a compressor.
Your kids still need a Pappy!!

My two cents............but I only weigh 150 lbs and never considered assembling by hand

Privateer · « **Reply #11 on:** June 21, 2014, 10:12:39 PM »

I'm about 150 myself. That piston will whip our behinds!

That bad boy needs a compressor! I just use a bar clamp that I picked up at home depot for about $20. Worked fine on my old walther talon mag (hatsan 125). A good pipe clamp or bar clamp will get the job done nicely, but be careful. Even with a nice spring compressor, things can go awry on you. Privateer- you're a bad dude brother! I would not even attempt the hattie 125 without some type of compressor. A spring like the one in this gun can kill you! I hope that nobody else tries...

Privateer · « **Reply #13 on:** June 21, 2014, 10:27:54 PM »

Mine was the Nitro Piston. 3/4 inch preload and I did take it apart with no compressor.
I couldn't get it back together though! It whooped me like a bad habit!

Bryan Heimann · « **Reply #14 on:** June 21, 2014, 10:40:10 PM »

I've read that the trail XL has about 1/4" of preload on the np, and can be disassembled safely with just a pillowcase to catch it on the way out. Kinda funny that the hatsan with the xl upgrade has about 3/4" preload. Makes you wonder about the ram and conversion parts used by pyramyd. Baybe it has a little more preload because the piston isn't nitched for the end of the ram. The 125 with the nitro sounds really nice, perect balance of power and hold sensitivity in a magnum breakbarrel. I am still scratching my head over the fact that it isn't offered for the 135. The difference in dimensions should be almost negligible for the conversion between the two.

I didn't have a compressor when I did mine either... Pappy. I hesitated for while then just decided to go for it! I used a big block of wood some screws and my 240lbs frame for leverage. Getting it back together took another set of hands to put the pin back in while I pushed on it for all she's worth. Would have been alot easier with a bar clamp but I'm a knucklehead who jumps in feet first! I later found an old rusty bar clamp laying in the farm workshop and that made my next tune alot easier. Get a walther talon seal from pa and good luck on that tune. It will be worth it!

I'll say this for what it is worth.
I have a brand new XL NP here right now. I could compress the NP in the Sniper when I took it apart.
This thing? It's a whole new beast! Now did they up the pressure or did I get weaker? I don't know.
But I can't wait to try it out! I've heard the new NP's are improved.
May be a whole new ball game if they are!

Great idea about the bar clamp! Oh and by the way I have up all my brownie points with my grand kids so no chances will be taken! This old mule ain't what it use to be and I am just happy I can hang around and graze! Lol

One more idea on topic of (dis)assembling.
On Russian YT video youtube.com/watch?v=qg5WwJI5WOI (about 8 and half minutes in video) I'we seen a cheap homemade tool for all springers. I'we built my one for under 10e (in Bosnia and Hercegovina). Be sure to use it even disassembling so ur spring doesn't fly trough window

Tommy · « **Reply #19 on:** June 24, 2014, 06:31:24 PM »

Please do not try without a spring compressor. There are lots of ideas on how to make one Mine cost me about $15
We would really like to have you around for awhile
Just make one You will be glad you did [and so will we]
