@WalnutandSteel Wow, 😮 That’s very interesting. Now I want to try one. I’m getting my first shipment from Buck-Rail next week. I bought a stock & Chis at Terry’s urging is including some extra goodies to support the channel. I’m excited to check it out.
Glad suggested videos feed caught my eye with these disassembly videos. I accidentally became a "young" Crosman guy, and enjoying getting to know my collection. Looking forward to learning more from you as I meander through the videos. Thank you for your contributions to the community, and subbed.
There using a 2260 valve and a discovery valve top and popet. They actually modified the top and cut it shorter but the intake hole is really tiny . It could be I'm use to the ones I've done I only leave enough to retain the spring not quite as big as the boss valve but pertty close. Basically if you drill and tap the valve for screw on each side it be a discovery for less than 15$ for extra 1000psi fill shh. 😊👍✌️
If so that means they went even cheap and there using a stock 1322 valve but flat topped it for fill and used a Benjamin p rod popet inside it. if it that small of a diameter around 🤔
@@josephsaucedo8691 , That’s more like it. I suspect the cost reduction is much more substantial by reducing the diameter of the tube. Containing the same pressure in a narrow tube requires substantially less strength than the same PSI in a fatter tube. This way they meet a 2000 psi safety margin with far cheaper tubing. IMO
If the hammer spring adjustment is the only way to degass it if you get a valve lock it is pretty scary... but I would assume there is an other way but they don't give you the tool with it unlike the Beeman Chief II I got on hand Not sure of what you mean by the valve on a 13xx is not secured by a screw the frame screw is going into the valve but I never took my 2240 completely appart yet to fully understand why the screw is coming out in the co2 to do nothing I still did not see any transfer port or rubber gasket this one doesn't have any?
Nope, I’m pretty certain about this. I’ve spoken to some other informed folks who agree. I don’t understand why you’d find buying a special tool to do something that you’re able to do with an Allen key better. You’re simply pressing the valve open manually rather than asking the hammer spring (as set from the factory) to do it under its own strength. If I’m correct, I submit that a simpler method not requiring tools is better. Looking at the design, I don’t see any other way. Do you?
@@AlsAirgunsMight be a fancy degassing tool that screws into the fill nipple But is that the actual hammer spring adjustment or there is a screw going through the adjustments that directly pushes the valve stem? Increasing the hammer tension is not a fix for valve lock... I mean yeah but nah what happens if you are already at a full hammer spring tension for full power?! (Atleast that's what I had understood) [Could look like this ; Challenger/ Discovery Degassing Tool Model: PCPDT3]
You’re assuming that Crosman intended the screw as a hammer spring adjuster. I’ve never seen Crosman refer to it as such. I don’t know that it was ever intended for users to play with. According to what I read it was for use by factory authorized service personnel to use as described in the manual. That manual describes it being used to cure valve lock on an approximately 2000 psi gun that sells for less than 150 bucks. Dude, relax it’s an airgun based on the 362 pump up pneumatic. It’s got more in common with you 1377 than it does a Discovery. The degassing tools you’re describing would cost 15-20% or the price of the gun. Many consider simplicity to be elegance of design. That’s what this gun represents. It’s not a disco, marauder, armada, or whatever. And that’s the good news, not the bad news. They could have built it like those. But then it would be priced like and handle like those guns.
Yes, I also modify 1377 to pump 50 times and clear the valve on each shot. Which Crosman didn’t intend. I apologize, I was being snippy. Now that I’ve had my coffee. The part you’re missing has to do with fluid (we treat air as a fluid in these examples) dynamics there’s a strange principle at work. Basically to contain say 2000 psi in a vessel that’s say 1 inch in diameter requires way more material strength. I’d have to look it up but like more than 4 times as much (the formulas are in the book on Man Powered Bullets by Middleton.) than it takes to contain the same 2000 psi in a vessel 1/2 that diameter. By using the reduced diameter of the Crosman pumper tubes and valves over the larger diameter tubes & valves used in 2240s, Discos and Marauders, they dramatically changed the strength requirements in a number of critical (but not immediately apparent areas.) These include valve and tube strength requirements but I also believe it affect spring force requirements as well. I believe the engineers have done their math properly. My belief is it’s been designed in away that adjusting what you & your stock drilling friends are calling a hammer spring adjuster as described in the repair manual will provide sufficient force/pressure/effect to clear valve lock in the smaller diameter valve at any pressure the overall system can contain. In other words for a user to put that much pressure in the gun (3800 psi say) something else (o-rings for example) will blow & release the pressure. These engineers do it fora living & Crosman over engineers everything. I’m hoping this helps. Otherwise: If enough people want me to, or if you make a very large super thanks. I’ll put my money where my mouth is & test it on my 3622. Sound fair? I like the 3622, I believe it’s well designed and I’m going to continue shooting & enjoying. I made a response on Nibs review complimenting him for not falling into the “it’s not a blah, blah trap. The Crosman product manager joined in on that thread and discussed some of the decisions that were made according to certain design goals they were given. You might want to check that out too. Be well & stay safe.
@@AlsAirgunsCool deal. Appreciate you taking the time to answer. I’ve been looking at this gun because of the price but wondered if it could be adjusted. At first I said no because of the open sights but learned that you could buy a breech block so I’m back looking at it. Lol.
There are things it doesn’t have or do. But what it does it does really well. Mine came adjusted to shoot a 14.3 grain Crosman or Benjamin pellet slightly over 700 FPS. That’s really all I need from it & exactly what I was looking for. Also, mine gets every bit of 25 shots per fill. Because I’m used to CO2 guns I’m often aware it’s getting low but just adjust my aim to compensate. When shooting for fun like that 30+ shots often happen. Good luck on your decision & purchase. Be well & thanks for commenting. 👍🏻
It depends on what you’re calling the main tube. If you mean, could you take your internals, hammer, valve & such from a 2240 and install them in a 3622 tube. The answer is no. The 2240 series uses a larger diameter tube and components. The 3622 uses the smaller diameter tubes and components we see in the 1377, 1322 & 362 pump up pneumatics. That being said, you can take your 2260 breech and barrel onto a complete 3622 bottom end as we call it (meaning tube and all internals, valve & so on.) Although the stock from the 2260 would fit poorly if you reused it. So not a real good reason to go that way.
@@AlsAirguns I would want to take my 2240’s breach and barrel plus trigger assembly and use the PCP tube of the 3622. I how you understand what i mean.
Yes, you will also need all of the 3622 internals to, valve, hammer, hammer spring, rear end cap, front fill adapter. And what will you use for barrel bands and a stock? Your 2260s won’t work. Yes you can reuse your barrel, breech and trigger group plus your sights. That’s it. You’ll need the 3622 stock & barrel bands for a decent fit. Btw, these parts will be pretty much impossible to source piecemeal these days & if you can they will be expensive. What I don’t understand is why you want to do this. So why?

Thanks for the tutorial!
Thanks! Trying to contribute to the sport. Some viewer was put out because I don’t shoot enough. I sent them to you. 😁
Nibs, I really enjoyed your grip frame review.
The trigger is amazingly better with that grip frame vs the stock trigger frame and I don’t know what the big difference is.
@WalnutandSteel Wow, 😮 That’s very interesting. Now I want to try one. I’m getting my first shipment from Buck-Rail next week. I bought a stock & Chis at Terry’s urging is including some extra goodies to support the channel. I’m excited to check it out.
Terry is actually the owner of the company Chris is his friend who helps Terry out with order taking and other stuff.

Thanks, you’re very much appreciated. Welcome.
You sure do not waste any time breaking into these guns.🤠
It’s a dirty job. But someone has to. 😎
he saved me money , I was going to buy one just to take it apart
That’s why I’m here…..
There is always SUPER THANKS 😊
Great information! Thanks for the in-depth tutorial.
My pleasure!

Do we need to use a drop or two of some lock tite on the screws on re-assembly?
I didn’t but because the tube is the pressure vessel I lubed the valve o-ring with silicone chamber oil rather than normal oil.
If the hammer spring adjustment is the only way to degass it if you get a valve lock it is pretty scary... but I would assume there is an other way but they don't give you the tool with it unlike the Beeman Chief II I got on hand

Could i swap the main tube on a 2240 for the PCP tube on a 2260?
The 2260 is not a PCP tube. The Discovery tube is a PCP tube of the correct diameter and folks have used it in the way you’re asking about.
@@AlsAirguns sorry i was meaning 3622 😜
