Crosman Pistol repair Mark II and 2240

I wish I still had my Diana 6.  For my use that was the perfect level of accuracy, power, and cocking effort.  The ones that got away!

on the  2240 you could simply, if the gas is coming out of the barrel the valve is leaking if not, the seal for the cartridge could be bad, it is a cheap pistol to practice on and not hard 

and if it a stock factory pistol it's not worth the 2 way shipping and the repair, just buy a new one 

the mark ll is another story but it could as simple as replacing the piercing cap o-rings, a very common problem 

there are 2 a small one on the pin and a large one on the cap to seal the tube 

sizes can be found and a repair kits are easy to find-------just a note never had either Mark l or ll apart 

on the 7-7 series Daisy great gun, i have 717 with a 747 trigger group and barrel with 777 grips 

you can find them on Ebay but there prices have gone up after they discontinued 

they are easy to work on and fun to shoot but shop wisely 

now on the Model 6, if you liked the pistol find another one but again it should be have a fresh within 5-8 year rebuild and if it has the factory target grips in nice shape they have a value of 80 buck in my mind 

so if you see a pistol that you can get for 300.00 subtract the grip target grips value, so the pistol is 220.00 of course it's just the way i look at thing 

the Giss pistols are not hard to work on but they are not easy because you need to have right tools and parts too complete a rebuild 

so just some info, ideas and opinions 

stay safe and take care

Thanks.  Makes sense, not economical to repair the 2240.

The Mark II, though.... I've watched some youtube and there is a lot to disassembling this thing.  Also I didn't see one that showed how to get the piercing pin O-ring out, but found a lot of comments about how hard this is.

I've had it 15 years or so, found it cheap at a yard sale, but it leaked and has sat in my healing pile ever since.  I think it's probably worth fixing right, if I can find the right place to send it to.  After this long it really should have everything replaced. 

Yeah, that Giss system was a pain to work on, I think I had it apart twice with good results.  It "disappeared" in one of my many moves.  I'm not looking for a replacement Diana 6 as much as an equivalent.  

The two that I've always coveted above all others are the F65 and the Webley Tempest.  Can't find either at a reasonable price.  

i have the Tempest and a Hurricane for no other reason other then, just because but for me they are used better as paper weights 

very harsh shot cycle 

the FWB 65 or 80 or 90 are must owns at one time or another 

the mark l or ll are worth repair 

if you like older pistols look at the S&W 78-79  even a Webley Alecto 

your choices are vast

Try Rick at Precision Pellet.

The 2240 is probably one of the least complicated co2's made, so it's pretty easy to re-seal. But if you aren't comfortable with the DIY approach I'll second having Rick@ Precision Pellet do both of them.

The 2240 is a super easy machine to work on. 

If I were you, I'd consider three things:

1) Talk to Crosman over the phone because you can get a lot of parts that are not normally offered via websales. 

2) Connect with these dudes: https://spares.bagnallandkirkwood.co.uk

3) Instead of simple repairs, install a bunch of upgrades! 

I bought an enlarged transfer port that came with a new port gasket.  You can buy replacement o-rings at ACE for almost every other seal inside the machine or from eBay to get "official" o-rings.  There is even a Russian video on how to steal tiny o-ring seals from propane lighters. ?   And, you'll have fun on the workbench while upgrading your machine.

so if the 2240 is leaking and will not hold gas long enough to use, it is broken 

so if you take the broken airgun apart which is easy and you can't get it repaired you have no hurt the pistol 

i don't think it would take more then 3 minutes to take it apart 

and i didn't see any mention of up grade from Tom's post 

hell you could just buy a complete valve and install it, it can leak from only two places gas in and gas out 

 There is a little seal on the 2240 valve that you seat the cartridge on that gets abuse from over-torqueing the cap. If you can hook it with a bent paper clip and flip it around you may be able to reseal it.

  Mike I just to tell you that you are a very helpful person.

thanks, i'm just a 70 year old guy that likes to help 

like you i have a mechanical back ground and many on the forums don't but they need to be able to understand the problem and have the courage to dive into a project or at lease try

the 2240 is easy and anyone should be able to do it, a FWB model 90 will make the first timer pucker just a little and most of that is about screwing up a 600.00 pistol vs a 50.00 pistol and i was there but i have do Giss pistols 

i have about 80 air guns so i have been in a few of them 

take care be safe and i'm always here to help as long as i'm here

I just installed the newer Crosman trigger assembly in my 1700,the newer model 1701 already has it,what a difference it made.

  Looks like me and millions of others will have plenty of time to get things done.....got to make the best of what is happening...and what is happening is crazy.

   Noah, I am over here!

on the trigger assembly for the that can be used in the 2240, i have never done it because i have too many 2240 custom pistols and would cost me a fortune

you know if you do one you would have to do them all and i'm lazy in my old age  and too many unfinished projects 

i got to get to work and order some trigger groups 

what hammer are you using 

I was able to use the stock one,have not adjusted anything,it is so much easier to pull,right now there is no play between first and second sage ,I will change that soon as I can find the right size allen wrench.I did install I wider one piece trigger...fat fingers need fat triggers.

Thanks for the advice.

I guess I'll attempt the 2240 myself and send the Mark II in.  

I am now kicking myself.  At the last Airgun Show in Roanoke, somebody quoted me a very good price to fix it.  To my regret I passed, but then Roanoke ended.  That was the time the show wasn't downtown, it was out a ways somewhere.  

This is a very helpful place!

Two year old thread, but I have an update.

I sent my Mark II in to Precision Pellet, he did a nice job job very quickly at a reasonable price.  I'm surprised by how many shots I get even in a rather cold basement.

I'm thinking to work on the 2240 myself.  Youtube makes it look easy.  A complete valve is only $20, a valve seal kit is almost that much with more chance to mess it up.

Oh, but..............could add the match trigger at $80 and the steel breech at $50, now I've got another $150 into it................nah.  Then I'm into Diana Chaser or Mrod CP-1 territory.  

I've avoided CO2 for a long time, but I'm enjoying shooting it again.  I still like the trigger on my P3 better than anything else I shoot but the cocking effort is just too much anymore.  If I could find CO2 with a trigger like that at a reasonable price I'd be happy I think, especially with a rail or dovetails.
